Peripheral Artery Disease
Evolving Role of Exercise Medical Therapy and
Endovascular Options
ABSTRACT
The prevalence of peripheral artery disease (PAD) continues to increase worldwide It is important to identify patients
with PAD because of the increased risk of myocardial infarction stroke and cardiovascular death and impaired quality of
life because of a profound limitation in exercise performance and the potential to develop critical limb ischemia Despite
effective therapies to lower the cardiovascular risk and prevent progression to critical limb ischemia patients with PAD
continue to be under-recognized and undertreated The management of PAD patients should include an exercise
program guideline-based medical therapy to lower the cardiovascular risk and when revascularization is indicated
an ldquoendovascular 1047297rstrdquo approach The indications and strategic choices for endovascular revascularization will vary
depending on the clinical severity of the PAD and the anatomic distribution of the disease In this review we
discuss an evidence-based approach to the management of patients with PAD (J Am Coll Cardiol 2016671338ndash57)
copy 2016 by the American College of Cardiology Foundation
Peripheral artery disease (PAD) refers to athero-
sclerosis involving the aorta iliac and lower-
extremity arteries and is associated with
signi1047297cant morbidity and mortality (12) Since the
last iteration of the guidelines focused on PAD ( 2ndash4)
published data have emerged that may alter the stan-
dard of care for this high-risk patient group This re-
view will delve in great detail into the management
of PAD patients highlighting the roles of exercise
optimal medical management and endovascular
therapy Surgical revascularization will not be dis-
cussed because current expert consensus documents
recommend an ldquoendovascular 1047297rstrdquo approach for the
majority of PAD patients requiring revascularization
(23)
Despite initiatives to improve on the identi1047297cation
and management of PAD (25) the number of people
affected and disease morbidity continues to rise As
of 2010 more than 200 million people worldwide areliving with PAD which represents a 287 increased
prevalence in low- and middle-income countries and
a 131 increase in high-income countries over a
10-year period (67) Prevalence studies in the United
States estimate that 59 of Americans over 40 years
of age have PAD (8) When speci1047297c high-risk pop-
ulations are evaluated estimates of PAD prevalence
are as high as 30 (9) The prevalence and severity of
PAD is increased in African Americans and Hispanics
(10) A recent retrospective cohort study evaluating
nearly 12 million insured American adults reported
mean annual incidence rates of PAD and critical limbischemia (CLI) of 235 and 035 respectively (11)
The risk factors for PAD mirror those of cerebrovas-
cular and coronary atherosclerosis including a posi-
tive family history diabetes mellitus smoking
chronic kidney disease hypertension and hyperlip-
idemia (59101213) Smoking and diabetes are
particularly virulent and are associated with worse
outcomes independent of other risk factors (14)
Identi1047297cation of patients with PAD is important
because there is a 3- to 4-fold incre ased risk of car-
diovascular events even in the setting of asymp-
tomatic disease (15) At 5 years approximately 1 of 5
patients with PAD will experience a nonfatal cardio-
vascular event and 15 to 20 will die (most of
cardiovascular causes) (816)
Most patients with PAD fall into 1 of 3 groups
classic claudication (10 to 30) atypical leg pain
(20 to 40) or asymptomatic (nearly 50) Formal
testing to assess functional capacity and endurance
shows signi1047297cant impairment in patients with PADeven if asymptomatic Although the majority of pa-
tients report leg symptoms other than classic claudi-
cation greater functional decline is associated with
greater severity of disease lower baseline ankle-
brachial index (ABI) and increased numbers of
cardiovascular events (17ndash20) In patients with CLI
outcomes are dire at 1 year 10 will experience a
fatal cardiovascular event and 25 will undergo limb
amputation (2)
Patient-reported symptoms underestimate PAD
prevalence and the physical examination is not a
reliable tool for the identi1047297cation of disease Diag-nosis and prevention of adverse outcomes may

therefore be elusive unless patients are
identi1047297ed with targeted diagnostic testing
(ie ankle-brachial index [ABI]) (21) T he
treatment of underlying cardiovascular risk
factors results in reduced morbidity and
mortality for patients with PAD although this
population continues to be under-recognized
and undertreated for their cardiovascular risk
(28) Among 7458 participants with PAD in
the 1999 to 2004 NHANES (National Health
and Nutrition Examination Survey) data only
305 of subjects were taking statins 249
were taking angiotensin-converting enzyme
inhibitors (ACEI) or angiotensin receptor
blockers and 358 were admini stered
aspirin Among patients with PAD (and no
other clinical cardiovascular disease) use of
multiple preventive therapies was associated
with a 65 lower all-cause mortality (hazard ratio
[HR] 035 p frac14 002) (8)
The diagnosis of PAD can be made using the ABI
Using a handheld continuous-wave Doppler device
the ABI can be measured by taking the higher of the
2 systolic pressures in the dorsalis pedis and posterior
tibial artery in each leg and dividing by the higher of
the brachial artery systolic blood pressures in each
arm An abnormal ABI is diagnostic for PAD (21)
A normal ABI is between 100 and 140 An ABI 090
demonstrates 90 sensitivity and 95 speci1047297city for
PAD and is the accepted threshold for diagnosis (221)
Values between 091 and 100 are considered border-
line however the cardiovascular event rate for an ABI
in this range is increased by 10 to 20 (21) At levels
gt140 the identi1047297cation of PAD is not accurate
because of the presence of arterial calci1047297cation and
noncompressibility of the blood vessels a 1047297nding
frequently encountered in the very elderly and in
those with diabetes and chronic kidney diseaseIn this
setting the toe-brachial index is used and considered
abnormal when lt070 (421) There is a strong and
consistent relationship between an abnormal ABI andthe presence of coronary or cerebrovascular disease
(51622) In addition the ABI is a predictor of cardio-
vascular morbidity and mortality independent of
clinical risk prediction scores such as the Framingham
Risk Score and other surrogate markers of systemic
atherosclerosis suchas the coronary calciumscore and
carotid artery intimal-medial thickness (23) There is
alsoa higher cardiovascular event ratein patientswith
PAD (even in asymptomatic patients) with known
coronary artery disease (CAD) (24)
Several consensus documents and practice guide-
lines recommend screening for the presence of PADusing the ABI in patients $65 years old or those who
are $50 years of age with a history of diabetes or
smoking (2ndash4925) The goal is to identify and treat
patients with increased cardiovascular risk Despite
these recommendations and the fact that nearly one-
half of all PAD patients are asymptomatic there is no
reimbursement for the performance of an ABI in the
absence of clinical symptoms of PAD Alternative
diagnostic methods for PAD are beyond the scope of
this review
Serum biomarkers have been used for risk predic-
tion and the detection of PAD (26) A combined
biomarker pro1047297le that includes fasting glucose high-
sensitivity C-reactive protein b2-microglobulin and
cystatin C demonstrated ef 1047297cacy in the identi1047297cation
of PAD and reclassi1047297cation of cardiovascular risk
assessment by Framingham Risk Score in patients who
would have otherwise been misidenti1047297ed (27) The
BRAVO (Biomarker Risk Assessment in Vulnerable
Outcomes) study evaluated 595 patients with PAD and
followed them for 3 years The primary outcome was
ischemic heart disease events (myocardial infarction
unstable angina or ischemic heart disease death) Of
the 50 participants who had an event the D-dimer was
higher 2 months before the event than the values 10
months 12 months 16 months 20 months 26 months
and 32 months before the event There was no change
in the serum amyloid A or CRP 2 months before an
event (28) Although there is a clear association
betwe en various biomar kers and PAD the overall
clinical value related to patient outcomes remains
unclear and thus there is no clinical bene1047297t in
measuring biomarkers at this time
THE ROLE OF EXERCISE
Patients with PAD have a profound limitation in
exercise performance that is related to a complex
pathophysiology (29) Although reduced exercise
performance is a hallmark of PAD the symptomatic
manifestations are quite varied as described previ-
ously (30) Not surprisingly patients with claudica-tion slow their walking pace and often avoid walking
altogether Thus patients with PAD present with a
complex array of symptoms health beliefs and
exercise limitations in their daily lives (3132) These
perceptions and attitudes must be addressed if a
treatment plan is to be successful
The overall goal in treating the exercise limitation
from PAD is to improve exercise performance with a
corollary improvement in quality of life (QOL) and
functional status In this regard treatments that
improve treadmill exercise performance 6-min
walking distance and patient-related QOL can serveas a basis for obtaining regulatory approval of a

claudication therapy In contrast changes in limb
hemodynamics such as an improvement in the ABI or
imaging after a successful revascularization serve
only as surrogate measures of clinical bene1047297t
Exercise training has been a mainstay of treatment
for symptomatic PAD with a well-established bene1047297t
after a typical 12-week exercise training program
(3334) Exercise training directly modi1047297es several
pathophysiological mechanisms in PAD including
improved skeletal muscle metabolism endothelial
function and gait biomechanics (35)
SUPERVISED EXERCISE TRAINING I MPROVES MORBIDITY
AND MORTALITY IN PAD Individual single-site studies
and a meta-analysis of those studies demonstrate that
a 12-week intervention of supervised exercise (SE)
improves exercise performance and QOL in PAD (34)Supervised exercise is also more effective than a
nonstructured community exercise program (36)
Physical activity in patients with PAD is associated
with decreased all-cause and cardiovascular mortality
(3738) Standardized supervised training methods
have been published previously (39)
On the basis of current evidence supervised
walking exercise gets a Class Ia recommendation and
unsupervised exercise a Class IIb recommendation
(2) Despite clear evidence of bene1047297t SE programs
have not been accepted by payers providers or
patients for a variety of reasons including questionsof long-term adherence and the bene1047297t of exercise as a
lifestyle intervention coupled with the desire by most
patients and vascular physicians for a more immedi-
ate approach to relieving claudication with endovas-
cular therapy (40) Therefore SE training programs
for claudication are very limited and not reimbursed
HOME-BASED EXERCISE DATA AND GENERALIZABILITY
OF THE FINDINGS The methodology to provide a
community (home)-based exercise intervention has
improved considerably over the past decade and
these exercise training methods have provided
encouraging resultsThe least resource-intensive home-based program
can employ education and behavioral interventions
that prepare patients for exercise training (41)
Notably adherence to a community program may be
poor without proper motivation and engagement
There are a number of new devices that monitor
the intensity and duration of an exercise session
performed in the home environment A pilot study
that used a program of training monitoring and
coaching had encouraging results in a subgroup of
subjects but was too small to de1047297nitively establish the
bene1047297ts of the interventions (42) Two larger trialsused a step activity monitor to record the duration
and intensity of the walking exercise to inform the
research staff and patient as to the patientrsquos exercise
prescription One randomized trial combined the
activity monitor with a home-based program that
used the principles of a hospital-based supervised
program (43) Adherence to the home program was
gt80 and the results on improvements in treadmill
exercise performance were comparable between
home and supervised programs A follow-up study
demonstrated similar results (44)
McDermott et al (45) have developed a coordinated
exercise program (group-mediated cognitive behav-
ioral therapy) that includes weekly group sessions run
by a trained facil itato r In a rando mized controlled
trial of 194 patients subjects in the intervention group
improved their 6-min walkingdistance peak treadmill
exercise performance and several measures of QOL
and accelerometer-measured physical activity (46)
In addition after 6 months the intervention group
gained self-ef 1047297cacy satisfaction with functioning
pain acceptance and social functioning and these
bene1047297ts weresustained at the 12-monthendpoint (47)
At 12 months fewer treated patients experienced
mobility loss and treated patients also improved in
walking velocity and QOL (48)
It is apparent that many of the exercise methods
discussed are effective in improving walking distance
with less discomfort and improved QOL however
they all require resources that are not available in
many communities especially those in the lowest
socioeconomic class Although a simple recommen-
dation between the physician and the patient to exer-
cise is usually ineffective the physician can provide
a comprehensive exercise prescription (Table 1) on
how to structure a home exercise program (5051)
This is not a 1-time recommendation but an ongoing
discussion between the physician and the patient
in an attempt to change patient behavior Patients
who are compliant with such a program often experi-
ence considerable improvement in walking distance

THERAPY ARE WE ASKING THE RIGHT QUESTIONS
Several studies have compared an SE program to
revascula ri za ti on i n p atients wi th PAD a nd
exercise-limiting claudication (5253) G iven t he
tremendous expansion and effectiveness of endovas-
cular treatments for symptomatic PAD as well as
patient reluctance to enter an exercise-lifestyle treat-
ment program (as discussed previously) the most
prudent approach would be to include both modalities
in the treatment plan exercise and revascularization
In fact both exercise training and revascularizationcan greatly improve patient exercise performance

and QOL but by very different mechanisms Revascu-
larization primarily improves exercise blood 1047298ow
whereas exercise training does not (29) In contrast
exercise training induces a variety of adaptive re-
sponses including improved skeletal muscle mito-
chondrial oxidative metabolismimproved endothelialfunction and more ef 1047297cient biomechanics of walking
Thus the obvious ldquo bestrdquo treatment strategy would
appear to be the combined program utilizing endo-
vascular revascularization and an optimal home-based
and long-term exercise program This hypothesis
was initially tested more than 25 years ago and the
combination of bypass surgery and exercise training
was superior to either treatment alone (54)
The CLEVER (Claudication Exercise Versus Endo-
luminal Revascularization) study was an important
and well-designed comparative effectiveness trial
that compared the outcomes for stenting of aortoiliacdisease with SE on a background of optimal medical
therapy in both groups (52) At the initial 6-month
follow up the primary endpoint of peak walking
time on a graded treadmill test was signi1047297cantly
improved in both the exercise and stent groups
compared with optimal medical management but the
peak walking time was signi1047297cantly higher in the
exercise group than in the stent group (52) The sec-
ondary endpoints were changes in responses to QOL
questionnaires Both of these patient-reported out-
comes were improved with exercise or stenting over
optimal medical management however improve-
ments tended to be greater in the stenting group The
same endpoints were measured at 18 months of
follow-up (55) In 79 of 119 patients who completed
the study improvements in treadmill peak walking
time remained for both the exercise and stenting
groups over optimal medical therapy but the differ-
ences in peak walking time between the exercise and
stenting groups were no longer statistically signi1047297-
cant Improved patient-reported outcomes remained
for both the exercise and stent groups
CLEVER clearly established the independent long-
term and broad-based bene1047297ts of both exercise
training and stent revascularization in symptomatic
PAD Similar to many such trials of the nearly 1000
patients evaluated only 11 were randomized and
fewer were available for 18-month follow-up Unfor-
tunately the arm of CLEVER that would have tested
the combination of exercise plus stenting was drop-
ped because of poor enrollment
In the recently published ERASE (Endovascular
Revascularization and Supervised Exercise) trial
106 patients were randomized to both endovascular
therapy and SE and 106 patients to SE alone (56) After
1 year the combination group had greater improve-
ment in maximum walking distance (MWD) and
health-related QOL scores than the group randomized
to SE alone however both groups demonstrated
dramatic improvement in MWD pain-free walking
distance and QOL The supervised exercise group
increased MWD from 285 m to 1240 m for animprovement of 955 m The combination group
increased MWD from 264 m to 1501 m for an
improvement of 1237 m This study illustrates
2 important points 1) the combinationof endovascular
therapy and SE is the most effective therapy for many
patients with claudication and 2) even the group
randomized to SE alone showed marked improvement
in MWD pain-free walking distance and QOL (56)
The cost of therapy must also be considered when
planning a particular strategy to treat symptomatic
PAD In a single-center Dutch randomized trial
endovascular revascularization had similar bene1047297t but highe r total mean cumula tive costs per patie nt
T A B L E 1 A Practical Home Exercise Program for Patients
With PAD
Frequency
3-5 days per week
Modality
Treadmill (this program can be adapted for walking outside)
Method
1 Begin at 2 mph and a grade of 0 (1047298at)
2 Try not to hold onto the treadmill Use the side panels for balanceonly
3 Stop the treadmill completely when pain is 3ndash4 on claudicationdiscomfort scale
4 When the discomfort has ceased resume exercise at the sameintensity
5 Repeat restexercise cycles
6 Progress to a higher workload when you can walk for 8 minwithout having to stop for leg symptoms
a) Increase speed by 02 mph each time you can walk for 8 min
b) Once you are able to walk at 34 mph or reach a speed at whichyou can no longer keep up begin increasing the grade by 1
Duration
The total exercise period including rest periods should equal45 min per day
Tips for success
1 Do not continue walking past 3ndash4 on claudication paindiscomfortscale This way the paindiscomfort should go away in 2ndash5 min If you walk until you are in severe pain you will build up lactic acidin your muscles and it will take much longer for the pain to goaway
2 When at 3ndash4 on paindiscomfort scale stop walking completelyDo not slow down but stop and stand on the treadmill until thediscomfort is gone
This works if you do it Not only will this improve your walkingperformance decrease your discomfort and improve your
quality of life this type of program is also bene1047297cial for yourheart blood pressure and lipid (cholesterol and triglyceride)levels

compared with a hospital-based exercise program
(57) Another study from a Dutch health-care databaseof 4954 patients demonstrated that a stepped
approach of exercise therapy followed by endovas-
cular revascularization was more cost-effective than
revascularization only (58)
Thus future studies should address not only the
clinical bene1047297ts but also the effectiveness of the
combination of an exercise program and limb revas-
cularization In this context effectiveness pertains to
the ability of a treatment program to be utilized by a
majority of appropriate patients in a community and
to achieve high adherence to the program as well as
that the desired improvements in functional out-comes are obtained
OPTIMAL MEDICAL THERAPY FOR
PATIENTS WITH PAD
Medical therapy for PAD should address treatment for
limb-related outcomes (improve claudication symp-
toms and prevent CLI and amputation) and treatment
to prevent major adverse cardiovascular events
(MACE myocardial infarction stroke and cardio-
vascular death) (Central Illustration)
Despite the recommendations from societal
guidelines on the management of patients with PAD(2) these patients continue to be undertreated
compared with patients with CAD (859) Adherence
to these guidelines in real-world practice is associatedwith improved outcomes (Figure 1) which empha-
sizes the bene1047297t of multifactorial risk reduction in
this high-risk population (12) Performance measures
for PAD will help improve quality of care and may be
incorporated into future quality metrics (60)
SMOKING CESSATION
Smoking is a major risk factor for the developmentand
progression of PAD A multidisciplinary approach to
smoking cessation should be used including group-
based programs and cognit ive beha viora l therapy
A recent study evaluated the association betweensuccessful quitting after endovascular intervention
and long-term outcomes (61) Among 739 patients
undergoing lower-extremity angiography 28 were
active smokers at the time of endovascular interven-
tion In the subsequent year 30 of active smokers
successfully quit Those who remained off tobacco
had signi1047297cantly lower 5-year mortality (14 vs 31)
and improved amputation-free survival (81 vs
60) Discontinuation of smoking is the most
important lifestyle modi1047297cation in preventing CLI
amputation and MACE in patients with PAD This
needs to be conveyed to the patient in an empatheticand nonjudgmental way during every of 1047297ce visit The

to abstain from smoking (62)
PHARMACOTHERAPY TO IMPROVE
CLAUDICATION SYMPTOMS
Cilostazol is a type III phosphodiesterase inhibitorwith a number of properties but the mechanism by
which cilostazol improves claudication is not known
(63) A pooled analysis of all of the randomized
trials shows an improvement in absolute claudica-
tion distance of approximately 50 compared with
placebo (64) Although cilostazol appears to be safe
for long-term administration adherence is low (gt60
discontinuation at 3 years) because of adverse effects
including headache palpitations and diarrhea (65)
Because of its mechanistic similarity to other type III
phosphodiesterase inhibitors such as milrinone cil-
ostazol is contraindicated in patients with a history of
heart failure The optimal dose of cilostazol is 100 mg
twice daily and it may take up to 4 months to derive
maximum bene1047297t from this drug (63)
Pentoxifylline is rarely used today to treat claudi-
cation because of a lack of ef 1047297cacy compared with
cilostazol Naftidrofuryl is a 5-HT2 antagonist that is
approved in Europe In a pooled analysis involving
888 patients randomized to naftidrofuryl there was a
26 increase in pain-free walking compared with
placebo (66) It is not available for use in the United
States
ACEIs
ACEIs are associated with a signi1047297cant reduction in
MACE among patients with PAD These data are
derived primarily from the HOPE (Heart Outcomes
Prevention Evaluation) trial which randomized 9297
high-risk patients with vascular disease or diabetes
plus 1 other risk factor to ramipril 10 mg daily
or placebo Among these 1966 patients with PAD
(423) were randomized to ramipril and 2085
(448) to placebo The primary outcome (myocardial
infarction stroke cardiovascular death) occurred in
143 of those without PAD versus 220 of those
with PAD (67) In the 5231 patients without PAD the
primary outcome was observed in 126 in the ram-
ipril group and 149 in the placebo arm In those with
an ABI lt06the primary outcome occurred in 164 in
the ramipril arm versus 22 in the placebo arm Thecardiovascular bene1047297t of ramipril applies to patients
with both asymptomatic and symptomatic PAD across
a broad range of ABI values (68) Similar results have
also been observed with telmisartan which suggests a
possible class effect of ACEIangiotensin receptor
blockade among patients with PAD (6970)
STATINS
High-intensity statin medications are recommended
for a ll pa ti ents with PAD on the basis of the
most recent American College of Cardiology (ACC)American Heart Association (AHA) guidelines which

emphasize cardiovascular risk over low-density lipo-
protein targets (71) The majority of the data in sup-
port of statin use in patients with PAD are derived
from subset analysis of larger clinical trials The
Medical Research CouncilBritish Heart Foundationrsquos
Heart Protection Study randomized 20536 high-risk
patients to simvastatin 40 mg daily or placebo (72)
All-cause mortality occurred in 129 of patients
randomized to simvastatin and 147 randomized to
placebo (22 relative risk reduction p frac14 00003)
Observational studies have also con1047297rmed the car-
diovascular and overall mortality bene1047297t of statins
among patients with more advanced PAD including
CLI (73)
Recent data suggest that statin use is also associ-
ated with a reduction in adverse limb outcomes
including amputation In the REACH (Reduction of
Atherothrombosis for Continued Health) registry
statin therapy was associated with a signi1047297cant
reduction in the combined endpoint of worsening
claudication new CLI new revascularization or
amputation (74) The absolute 4-year event rates were
220 versus 262 which emphasizes the highrate of
adverse limb events among patients with symptom-
atic PAD Importantly statin therapy was also associ-
ated with a signi1047297cant reduction in 4-year rates of
ischemic amputation (38 vs 56) In an analysis of
Medicare claims data of patients undergoing lower-
extremity revascularization statin use was associ-
ated with lower rates of amputation at 30 days
90 days and 1 year (75) Single-center observational
data among patients with CLI suggest that statin
therapy is also associated with improved 1-year rates
of primary patency secondary patency and improved
limb salvage after endovascular intervention (73)
Patients with PAD should be prescribed a high-
intensity statin to reduce the risk of cardiovascular
events In most studies the rates of statin prescrip-
tion were lt75 which emphasizes the importance of
maximizing medical therapy among this high-risk
group of patients with advanced atheroscleroticdisease (59)
ANTIPLATELET THERAPY
ASPIRIN Aspirin has been a mainstay of drug ther-
apy among patients with PAD however the data
supporting aspirin use in patients with PAD have not
been well subst antia ted (7677)
Recent studies investigating the bene1047297t of aspirin
among patients with asymptomatic PAD have yielded
negative results Both the POPADAD (Prevention of
Progression of Arterial Disease and Diabetes) trial and
the AAA (Aspirin for Asymptomatic Atherosclerosis)
trial compared low-dose aspirin with placebo in
patients with a low ABI Neither study demonstrated
a reduction in fatal and nonfatal cardiovascular
events or revascularization with aspirin mono-
therapy although both notably included low-risk
patients with borderline ABI (099 in POPADAD
and 095 in AAA) (7778)
Consistent with these results a meta-analysis
speci1047297cally examined aspirin for PAD in 18 trials
involving 5269 patients In patients taking aspirin
monotherapy there was a nonsigni1047297cant reduction
in cardiovascular events (absolute event rate 82
vs 96 relative risk 075 95 con1047297dence inter-
val [CI] 048 to 118) however there was a sig-
ni1047297cant reduction in nonfatal stroke (HR 064 95
CI 042 to 099 p frac14 004) (76) In the last iteration
of the PAD guidelines (2) aspirin was a Class I
Level of Evidence A recommendation among pa-
tients with symptomatic PAD a Class IIa recom-
mendation among patients with asymptomatic PAD
and an ABI lt090 and a Class IIb indication among
asymptomatic patients with an ABI of 090 to 099
(2) Some of these recommendations may change in
the upcoming revision of the ACCAHA PAD prac-
tice guidelines
CLOPIDOGREL AND
DUAL-ANTIPLATELET THERAPY
Clopidogrel is indicated as an alternative to aspirin
for antiplatelet monotherapy among patients with
PAD although recent studies suggest that lt20 of
patients with PAD are prescribed clopidogrel in clin-
ical practice (79) The data supporting clopidogrel use
are primarily based on the CAPRIE (Clopidogrel
Versus Aspirin in Patients at Risk of Ischaemic
Events) study in which clopidogrel monotherapy was
associated with a small bene1047297t compared with aspirin
325 mg daily in the overall population but there was a
238 relative risk reduction among the subgroup of
patients with symptomatic PAD (n frac14 6452 absolute
event rate 37 vs 49 per year) (80)
Dual-antiplatelet therapy (DAPT) with low-dose
aspirin (75 to 162 mg daily) and clopidogrel 75 mg
daily was studied in the CHARISMA (Clopidogrel for
High Atherothrombotic Risk and Ischemic Stabiliza-
tion Management and Avoidance) trial which
included patients at high risk for atherothrombotic
events The overall results of this trial were not sig-
ni1047297cant although in subgroup analyses there was a
bene1047297t of DAPT among patients with symptomatic
atherothrombosis (81) In an analysis of the 3096 pa-
tients in the trial with PAD DAPT was associated with
a lower rate of myocardial infarction (23 vs 37

composite primary endpoint (82) There was no dif-
ference between the groups in moderate severe or
fatal bleeding but there was an increase in minor
bleed ing i n th e DAPT group
In a recent propensity-matched observational
study among patients undergoing endovascular
intervention there was a signi1047297cant reduction in
MACE among patients taking DAPT (adjusted HR
065 95 CI 044 to 096 p frac14 003) compared with
those taking aspirin monotherapy (83) The discor-
dant 1047297ndings between this study and the CHARISMA
trial may be explained by inclusion of a cohort
with more advanced atherosclerotic disease under-
going endovascular intervention including gt50 of
patients with CLI
The CASPAR (Clopidogrel and Acetylsalicylic Acid
in Bypass Surgery for Peripheral Arterial Disease) trial
studied DAPT versus aspirin 75 to 100 mg daily among
patients undergoing below-knee surgical bypass for
treatment of CLI (84) The primary endpoint of death
major amputation index-graft occlusion or revascu-
larization was not different for DAPT versus
acetylsalicylic acid (ASA) monotherapy In a pre-
speci1047297ed subgroup analysis there was a signi1047297cant
bene1047297t of DAPT in patients treated with prosthetic
grafts (HR 065 95 CI 045 to 095 p frac14 0025) but
not in those treated with vein grafts A similar trial
the CAMPER study (Clopidogrel and Aspirin in the
Management of peripheral Endovascular Revascular-
ization) tested DAPT versus aspirin in patients un-
dergoing infrainguinal endovascular therapy The
study was never completed because of poor enroll-
ment (doctors would not randomize patients to ASA
alone) continued funding could not be justi1047297ed
DAPT is often prescribed after endovascular inter-
vention although the data supporting duration of
DAPTare sparseIn practice most physicians prescribe
DAPTfor a time periodrangingfrom1 to3 monthspost-intervention The ASPIRE-PAD study (Antiplatelet
Strategy for Peripheral Arterial Interventions for
Revascularization of Lower Extremities) is currently
evaluating comparative outcomes of 1 versus 12
months of DAPT after endovascular intervention (85)
VORAPAXAR
Thrombin acts through platelets via a unique mecha-
nism binding of the protease activating receptor-1
(PAR-1) a G protein-coupled receptor expressed on
the platelet surface leads to receptor activation
and increased intracellular Ca2thorn cyclic adenosine
monophosphate (cAMP) levels subsequently decrease
which leads to increased platelet aggregation and
releaseof further activatingfactors Vorapaxar inhibits
PAR-1 thereby signi1047297cantly reducing thrombin-
mediated platelet activation
T he T RA 2P-TIMI 50 trial (Thrombin Receptor
Antagonist for Secondary PreventionndashThrombolysis
in Myocardial Infarction Study Group) studied vor-
apaxar sulfate 25 mg daily versus placebo (ASA and
or clopidogrel therapy at the investigatorsrsquo discre-
tion) among 26449 patients with a recent myocardial
infarction recent ischemic stroke or symptomatic
PAD At 3 years there was a signi1047297cant reduction in
the primary endpoint of MACE (absolute event rates
93 vs 105 HR 087 95 CI 080 to 094
p lt 0001) (79) After 2 years the data and safety
monitoring board recommended stopping the study
drug in the patient subgroup entered with prior
ischemic stroke because of an increased risk of
intracranial hemorrhage Among the 3787 patients
with PAD the majority were treated with aspirin
monotherapy plus vorapaxar or placebo The reduc-
tion in MACE was not statistically signi1047297cant in those
assigned to vorapaxar (absolute event rates 113 vs
119 HR 094 95 CI 078 to 114) Similarly
negative results were observed among patients with
PAD who were enrolled in the TRACER (Thrombin
Receptor Antagonist for Clinical Event Reduction in
Acute Coronary Syndrome) trial (86) Additionally
vorapaxar is associated with a signi1047297cantly increased
risk of major bleeding However in both of these
trials there were relatively few MACE in the PAD
subgroup The PAD group was underpowered to draw
any conclusions on ef 1047297cacy
Pre-speci1047297ed analysis of limb-related outcomes in
the TRA 2P-TIMI 50 trial demonstrated that patients
assigned to vorapaxar had signi1047297cantly reduced rates
of acute limb ischemia (23 vs 39 HR 058 95
CI 039 to 086 p frac14 0006) as well as peripheral
artery revascularization (184 vs 222 HR 084
95 CI 073 to 097 p frac14 0017) during the 3-yearfollow-up (Figure 2) (87) These ef 1047297cacy endpoints
must be balanced by a signi1047297cantly increased rate of
major bleeding among patients prescribed vorapaxar
Further research into the mechanism by which
vorapaxar led to improved limb outcomes is required
to fully understand these effects
CELL-BASED AND ANGIOGENIC THERAPIES
Modulation and enhancement of lower-extremity
blood 1047298ow via angiogenesis arteriogenesis or vas-
culogenesis could provide a promising breakthrough
therapy for patients with PAD (88) Additionally

there has been much interest in the use of stem cellndash
derived endothelial cells or modi1047297cation of resident
stem cells (89) Potential bene1047297ts of these therapies
include improved wound healing and limb salvage
among patients with CLI as well as improved clau-
dication distance To date numerous cell-based and
angiogenic therapies have been tested and despite
promising results in early clinical trials none of these
agents have shown bene1047297t in larger trials
ONGOING CLINICAL TRIALS
There are currently 2 clinical trials studying novel
antiplatelet and anticoagulant agents to reduce MACE
and potentially modify limb-related outcomes
EUCLID (Study Comparing Cardiovascular Effects of
Ticagrelor and Clopidogrel in Patients With Periph-eral Artery Disease) is a randomized blinded double-
dummy trial comparing ticagrelor 90 mg twice daily
to clopidogrel monotherapy among 13500 patients
with PAD (90) All patients are tested for clopidogrel
resistance before randomization The primary
endpoint is a composite of MACE and results are
expected in late 2016 The COMPASS (Rivaroxaban for
the Prevention of Major Cardiovascular Events in
Coronary or Peripheral Artery Disease) trial is evalu-
ating low-dose rivaroxaban alone versus placebo
aspirin alone or rivaroxaban and aspirin among
21400 patients with a history of myocardial infarc-tion or PAD the primary endpoint of this trial is a
composite of MACE (91)
ENDOVASCULAR THERAPY
Endovascular revascularization plays a key role in the
management of patients with PAD Patients with sta-
ble cl audication have a low ris k of lim b loss but may be
severely limited by their symptoms In most circum-
stances patients with claudication should be offered a
trial of cilostazol and an exercise program as initial
therapy If the patient is not satis1047297ed after a trial of
medical therapy endovascular revascularization can be consi dere d Patie nts with CLI require more urgent
revascularization because of an increased riskof tissue
loss and amputation as well as an extremely high risk
of cardiovascular events (92)
There are 2 well-established classi1047297cation schemes
to describe the severity of PAD The 1047297rst is a func-
tional assessment (Fontaine or Rutherford classi1047297ca-
tion [RC]) (Table 2) and the second is an anatomic
lesion classi1047297cation (Trans-Atlantic Inter-Society
Consensus [TASC]) (Table 3) (45) In addition there
has been recent interest in the angiosome concept in
helping to in1047298uence optimal revascularization stra-tegies for limb salvage (93) An angiosome is an
anatomic unit of tissue (consisting of skin subcu-
taneous tissue fascia muscle and bone) that is fed
by a source arte ry and drai ned by speci1047297c veins
If the patient is a candidate for either endovascular
or open surgery the less invasive option (ie an
endovascular-1047297rst strategy) is the current standard of
care The selection of a complex lesion (TASC D) for
endovascular therapy will vary with the skill and
experience of the interventionalist The goal in
treating a patient who has functional impairment
because of claudi cation is dura ble relief of symptoms
In patients with CLI and a threatened limb or tissueloss the goal is rapid reperfusion of the ischemic

AORTOILIAC OCCLUSIVE DISEASE
There has been a practice shift over the past 25 years
as the treatment of aortoiliac disease transitioned
from open surgery with aortobiiliac or aortobifemoral
bypass to endovascular trea tment s for comple x and
diffuse disease (TASC D) This preference for less
invasive therapy is evidence based and driven by
shorter length of stay (or treatment as an outpatient
entirely) and lower periprocedural morbidity and
mortality rates while achieving comparable patency
rates (4- to 5-year primary patency of 60 to 86
with secondary patency rates of 80 to 98) (94)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) In 2011 the European Society of Car-
diology (ESC) (3) and ACCAHA PAD guidelines (2)
recommended an endovascular-1047297rst approach for
aortoiliac lesions recommended that borderline
lesions be assessed with hemodynamic gradients and
supported primary stent placement in the aortoiliac
arteries (Table 4) The current expert consensus
document from the Society for Cardiac Angiography
and Interventions (SCAI) on appropriate use criteria
(AUC) for aortoiliac intervention are similar to the
current guidelines (95)

Treatment of TASC A B C and D Iliac Lesions) re-
ported 100 technical success in 325 patients with
aortoiliac lesions with a 24-month primary patency
rate of 879 (96) Neither TASC category nor lesion
length was predictive of restenosis These data
further support the endovascular-1047297rst strategy
regardless of TASC classi1047297cation and take into
consideration the evolution of devices (ie re-entry
catheters crossing devices and stents) which
improve success rates for the most complex lesions
COMMON FEMORAL DISEASE
Patients with common femoral artery (CFA) disease
are particularly symptomatic because the obstruction
not only occurs proximal to the super1047297cial femoral
artery (SFA) but also proximal to the deep femoralartery (profunda femoris) which is the major collat-
eral artery supplying blood to the lower limb when
there is SFA obstruction Traditionally common
femoral endarterectomy has been the CFA revascu-
larization procedure of choice (23) although
advances in endovascular therapy have shown some
promising results (97) A review of the National Sur-
gical Quality Improvement Program database for 2005
to 2010 found a combined mortality and morbidity
rate of 15 for common femoral endarterectomy
which was higher than expected (98) Patients
requiring CFA revascularization who are at increasedsurgical risk may be considered for less invasive
endovascular options
FEMORAL-POPLITEAL DISEASE
This segment begins at the bifurcation of the CFA into
the SFA and the deep femoral (profunda femoris)
artery The SFA is subject to 1047298exion elongation
compression and torsion unlike any other lower-
extremity artery This complexity leads to many
challenges for endovascular technology but despite
this an endovascular-1047297rst approach is currently thestandard of therapy for the majority of lesions
becau se of the very high proce dural success rate and
low risk (3) Some of the most lengthy and complex
lesions (TASC D) are more approachable because of
the re-entry and crossing devices more experienced
operators drug-eluting stents (DES) (99100) and
drug-coated balloons (DCBs) (101ndash107) that promise
improved long-term patency for patients with clau-
dication (99100103105)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines and the AUC documentfrom the SCAI recommend revascularization in
femoral-popliteal lesions for patients with CLI or for
patients with claudication who have had a suboptimal
r espon se to a tr ial of e xer cise (Tab le 5) An
endovascular-1047297rst approach is recommended for
TASC A through C lesions and is a reasonable option
for TASC D lesions depending on the experience of
the operator the patientrsquos comorbidities and proce-
dure safety (Table 5) (2395)
The 2 guidelines are in con1047298ict over the use of
primary stent placement in the femoral-popliteal ar-
teries with the ACCAHA guideline giving it a Class III
recommendation (do not do) and the ESC guideline
making primary femoral stenting reasonable 1047297rst-line
therapy (Class IIa) for intermediate-length lesions
(108109) The current evidence from several ran-
domized controlled trials supports primary stenting
in intermediate-length femoral stenoses and occlu-
sions (108ndash110) The soon-to-be-published updatedACCAHA guidelines will readdress this issue In

evidence suggesting that the more expensive athe-
rectomy devices cryoplasty or laser angioplasty
should be preferred over conventional therapy
(percutaneous transluminal angioplasty [PTA] and
bare- metal stents [BMS] ) The ESC guideline disti n-
guishes bare-metal self-expanding stents from
adjunctive devices such as atherectomy devices cit-
i ng the p roven bene1047297t of BMS over PTA in
intermediate-length femoral-popliteal lesions
CLINICAL TRIAL UPDATE Three randomized controlledtrials of self-expanding BMS compared with PTA have
shown that the advantage for primary stenting is
related to lesion length For relatively discrete lesions
(mean 45 mm) (110) there was no advantage for pri-
mary stent placement however 2 other trials
(108109) with longer lesions (gt70 mm) showed a
signi1047297cant patency and functional bene1047297t for primary
femoral-popliteal BMS (Figure 3 Table 6) The proce-
dural success rate of endovascular therapy in
femoral-popliteal lesions is very high but in stable
limb ischemia durable patency remains a barrier
Cilostazol has been shown to reduce 1-year restenosis by more than one-half (20 vs 49 p frac14 00001) in
intermediate-length (128 mm) femoral lesions treated
with self-expanding BMS (114) These results need to
be con1047297rmed before this can be recommended as
standard therapy
Recent randomized controlled trials demonstrating
bene1047297t f or DE S (99100) DC B (103105106) and
covered stents (115ndash117) in femoral-popliteal arteries
will likely result in a change in the guidelines and
indications (Table 6 Figure 3)
There hasbeen some enthusiasm for self-expanding
covered (expanded polytetra1047298uoroethylene) stent
grafts in complex or lengthy femoral-popliteal seg-
ments Two randomized trials comparing covered
stents to BMS had divergent results One showed a
bene1047297t for 2-year primary patency but no difference in
target-lesion revascularization (TLR) or clinical out-
comes (116) whereas the other in longer (gt8 cm) le-
sions found no difference for primary patency (115ndash
117) When covered stents were compared with
above-the-knee femoral bypass with synthetic graft
material in a broad range of SFA lesion types (TASC A
thru D) no difference was found in the 4-year primary
patency between the 2 options (118)
The Zilver paclitaxel-eluting self-expanding DES
was superior to PTA in a randomized femoral-
popliteal trial with 1-year patency rates of 831 for
primary DES and 328 for PTA (p lt 0001) (Figure 3
Table 6) (99) There was also a 1-year patency
advantage for provisional DES after failed PTA
(899) compared with provisional BMS (730
p frac14 001) The bene1047297t was sustained at 2 years with
primary patency for the DES (748) signi1047297cantly
better t han PTA (265 p lt 001) (100) To date there
has been no head-to-head comparison of primary DES
to either BMS or DCB in femoral-popliteal arteries
but Zelle r et al (104) published a propensity scorendash
based compar ison of DES and DCB in conse cutive
patients with TASC C and D long (gt10 cm) lesions and
found no signi1047297cant differences in 1-year patency
(Figure 3 Table 6)
DCBs offer the promise of improved patency with areduced need for stents This is particularly important
in the dynamic environment of the super1047297cial femoral
and popliteal arteries where mechanical fatigue may
lead to stent fracture and increased risk of in-stent
restenosis Each DCB is unique with respect to the
paclitaxel dose (varying from 2 to 35 mgmm2) the
carrier molecule (excipient) the balloon material and
the coating technology used Superiority for paclitaxel
DCB over PTA was 1047297rst reported in 2008 (101102)
(Figure 3 Table 6) Subsequently new DCBs have
emerged including the INPACT (105106111113) and
the Lutonix (103106) balloons both of which showedclinical superiority to PTA in femoral-popliteal lesions

TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators

is in establishing ongoing procedures to ensure

CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

Peripheral Artery Disease
Evolving Role of Exercise Medical Therapy and
Endovascular Options
ABSTRACT
The prevalence of peripheral artery disease (PAD) continues to increase worldwide It is important to identify patients
with PAD because of the increased risk of myocardial infarction stroke and cardiovascular death and impaired quality of
life because of a profound limitation in exercise performance and the potential to develop critical limb ischemia Despite
effective therapies to lower the cardiovascular risk and prevent progression to critical limb ischemia patients with PAD
continue to be under-recognized and undertreated The management of PAD patients should include an exercise
program guideline-based medical therapy to lower the cardiovascular risk and when revascularization is indicated
an ldquoendovascular 1047297rstrdquo approach The indications and strategic choices for endovascular revascularization will vary
depending on the clinical severity of the PAD and the anatomic distribution of the disease In this review we
discuss an evidence-based approach to the management of patients with PAD (J Am Coll Cardiol 2016671338ndash57)
copy 2016 by the American College of Cardiology Foundation
Peripheral artery disease (PAD) refers to athero-
sclerosis involving the aorta iliac and lower-
extremity arteries and is associated with
signi1047297cant morbidity and mortality (12) Since the
last iteration of the guidelines focused on PAD ( 2ndash4)
published data have emerged that may alter the stan-
dard of care for this high-risk patient group This re-
view will delve in great detail into the management
of PAD patients highlighting the roles of exercise
optimal medical management and endovascular
therapy Surgical revascularization will not be dis-
cussed because current expert consensus documents
recommend an ldquoendovascular 1047297rstrdquo approach for the
majority of PAD patients requiring revascularization
(23)
Despite initiatives to improve on the identi1047297cation
and management of PAD (25) the number of people
affected and disease morbidity continues to rise As
of 2010 more than 200 million people worldwide areliving with PAD which represents a 287 increased
prevalence in low- and middle-income countries and
a 131 increase in high-income countries over a
10-year period (67) Prevalence studies in the United
States estimate that 59 of Americans over 40 years
of age have PAD (8) When speci1047297c high-risk pop-
ulations are evaluated estimates of PAD prevalence
are as high as 30 (9) The prevalence and severity of
PAD is increased in African Americans and Hispanics
(10) A recent retrospective cohort study evaluating
nearly 12 million insured American adults reported
mean annual incidence rates of PAD and critical limbischemia (CLI) of 235 and 035 respectively (11)
The risk factors for PAD mirror those of cerebrovas-
cular and coronary atherosclerosis including a posi-
tive family history diabetes mellitus smoking
chronic kidney disease hypertension and hyperlip-
idemia (59101213) Smoking and diabetes are
particularly virulent and are associated with worse
outcomes independent of other risk factors (14)
Identi1047297cation of patients with PAD is important
because there is a 3- to 4-fold incre ased risk of car-
diovascular events even in the setting of asymp-
tomatic disease (15) At 5 years approximately 1 of 5
patients with PAD will experience a nonfatal cardio-
vascular event and 15 to 20 will die (most of
cardiovascular causes) (816)
Most patients with PAD fall into 1 of 3 groups
classic claudication (10 to 30) atypical leg pain
(20 to 40) or asymptomatic (nearly 50) Formal
testing to assess functional capacity and endurance
shows signi1047297cant impairment in patients with PADeven if asymptomatic Although the majority of pa-
tients report leg symptoms other than classic claudi-
cation greater functional decline is associated with
greater severity of disease lower baseline ankle-
brachial index (ABI) and increased numbers of
cardiovascular events (17ndash20) In patients with CLI
outcomes are dire at 1 year 10 will experience a
fatal cardiovascular event and 25 will undergo limb
amputation (2)
Patient-reported symptoms underestimate PAD
prevalence and the physical examination is not a
reliable tool for the identi1047297cation of disease Diag-nosis and prevention of adverse outcomes may

therefore be elusive unless patients are
identi1047297ed with targeted diagnostic testing
(ie ankle-brachial index [ABI]) (21) T he
treatment of underlying cardiovascular risk
factors results in reduced morbidity and
mortality for patients with PAD although this
population continues to be under-recognized
and undertreated for their cardiovascular risk
(28) Among 7458 participants with PAD in
the 1999 to 2004 NHANES (National Health
and Nutrition Examination Survey) data only
305 of subjects were taking statins 249
were taking angiotensin-converting enzyme
inhibitors (ACEI) or angiotensin receptor
blockers and 358 were admini stered
aspirin Among patients with PAD (and no
other clinical cardiovascular disease) use of
multiple preventive therapies was associated
with a 65 lower all-cause mortality (hazard ratio
[HR] 035 p frac14 002) (8)
The diagnosis of PAD can be made using the ABI
Using a handheld continuous-wave Doppler device
the ABI can be measured by taking the higher of the
2 systolic pressures in the dorsalis pedis and posterior
tibial artery in each leg and dividing by the higher of
the brachial artery systolic blood pressures in each
arm An abnormal ABI is diagnostic for PAD (21)
A normal ABI is between 100 and 140 An ABI 090
demonstrates 90 sensitivity and 95 speci1047297city for
PAD and is the accepted threshold for diagnosis (221)
Values between 091 and 100 are considered border-
line however the cardiovascular event rate for an ABI
in this range is increased by 10 to 20 (21) At levels
gt140 the identi1047297cation of PAD is not accurate
because of the presence of arterial calci1047297cation and
noncompressibility of the blood vessels a 1047297nding
frequently encountered in the very elderly and in
those with diabetes and chronic kidney diseaseIn this
setting the toe-brachial index is used and considered
abnormal when lt070 (421) There is a strong and
consistent relationship between an abnormal ABI andthe presence of coronary or cerebrovascular disease
(51622) In addition the ABI is a predictor of cardio-
vascular morbidity and mortality independent of
clinical risk prediction scores such as the Framingham
Risk Score and other surrogate markers of systemic
atherosclerosis suchas the coronary calciumscore and
carotid artery intimal-medial thickness (23) There is
alsoa higher cardiovascular event ratein patientswith
PAD (even in asymptomatic patients) with known
coronary artery disease (CAD) (24)
Several consensus documents and practice guide-
lines recommend screening for the presence of PADusing the ABI in patients $65 years old or those who
are $50 years of age with a history of diabetes or
smoking (2ndash4925) The goal is to identify and treat
patients with increased cardiovascular risk Despite
these recommendations and the fact that nearly one-
half of all PAD patients are asymptomatic there is no
reimbursement for the performance of an ABI in the
absence of clinical symptoms of PAD Alternative
diagnostic methods for PAD are beyond the scope of
this review
Serum biomarkers have been used for risk predic-
tion and the detection of PAD (26) A combined
biomarker pro1047297le that includes fasting glucose high-
sensitivity C-reactive protein b2-microglobulin and
cystatin C demonstrated ef 1047297cacy in the identi1047297cation
of PAD and reclassi1047297cation of cardiovascular risk
assessment by Framingham Risk Score in patients who
would have otherwise been misidenti1047297ed (27) The
BRAVO (Biomarker Risk Assessment in Vulnerable
Outcomes) study evaluated 595 patients with PAD and
followed them for 3 years The primary outcome was
ischemic heart disease events (myocardial infarction
unstable angina or ischemic heart disease death) Of
the 50 participants who had an event the D-dimer was
higher 2 months before the event than the values 10
months 12 months 16 months 20 months 26 months
and 32 months before the event There was no change
in the serum amyloid A or CRP 2 months before an
event (28) Although there is a clear association
betwe en various biomar kers and PAD the overall
clinical value related to patient outcomes remains
unclear and thus there is no clinical bene1047297t in
measuring biomarkers at this time
THE ROLE OF EXERCISE
Patients with PAD have a profound limitation in
exercise performance that is related to a complex
pathophysiology (29) Although reduced exercise
performance is a hallmark of PAD the symptomatic
manifestations are quite varied as described previ-
ously (30) Not surprisingly patients with claudica-tion slow their walking pace and often avoid walking
altogether Thus patients with PAD present with a
complex array of symptoms health beliefs and
exercise limitations in their daily lives (3132) These
perceptions and attitudes must be addressed if a
treatment plan is to be successful
The overall goal in treating the exercise limitation
from PAD is to improve exercise performance with a
corollary improvement in quality of life (QOL) and
functional status In this regard treatments that
improve treadmill exercise performance 6-min
walking distance and patient-related QOL can serveas a basis for obtaining regulatory approval of a

claudication therapy In contrast changes in limb
hemodynamics such as an improvement in the ABI or
imaging after a successful revascularization serve
only as surrogate measures of clinical bene1047297t
Exercise training has been a mainstay of treatment
for symptomatic PAD with a well-established bene1047297t
after a typical 12-week exercise training program
(3334) Exercise training directly modi1047297es several
pathophysiological mechanisms in PAD including
improved skeletal muscle metabolism endothelial
function and gait biomechanics (35)
SUPERVISED EXERCISE TRAINING I MPROVES MORBIDITY
AND MORTALITY IN PAD Individual single-site studies
and a meta-analysis of those studies demonstrate that
a 12-week intervention of supervised exercise (SE)
improves exercise performance and QOL in PAD (34)Supervised exercise is also more effective than a
nonstructured community exercise program (36)
Physical activity in patients with PAD is associated
with decreased all-cause and cardiovascular mortality
(3738) Standardized supervised training methods
have been published previously (39)
On the basis of current evidence supervised
walking exercise gets a Class Ia recommendation and
unsupervised exercise a Class IIb recommendation
(2) Despite clear evidence of bene1047297t SE programs
have not been accepted by payers providers or
patients for a variety of reasons including questionsof long-term adherence and the bene1047297t of exercise as a
lifestyle intervention coupled with the desire by most
patients and vascular physicians for a more immedi-
ate approach to relieving claudication with endovas-
cular therapy (40) Therefore SE training programs
for claudication are very limited and not reimbursed
HOME-BASED EXERCISE DATA AND GENERALIZABILITY
OF THE FINDINGS The methodology to provide a
community (home)-based exercise intervention has
improved considerably over the past decade and
these exercise training methods have provided
encouraging resultsThe least resource-intensive home-based program
can employ education and behavioral interventions
that prepare patients for exercise training (41)
Notably adherence to a community program may be
poor without proper motivation and engagement
There are a number of new devices that monitor
the intensity and duration of an exercise session
performed in the home environment A pilot study
that used a program of training monitoring and
coaching had encouraging results in a subgroup of
subjects but was too small to de1047297nitively establish the
bene1047297ts of the interventions (42) Two larger trialsused a step activity monitor to record the duration
and intensity of the walking exercise to inform the
research staff and patient as to the patientrsquos exercise
prescription One randomized trial combined the
activity monitor with a home-based program that
used the principles of a hospital-based supervised
program (43) Adherence to the home program was
gt80 and the results on improvements in treadmill
exercise performance were comparable between
home and supervised programs A follow-up study
demonstrated similar results (44)
McDermott et al (45) have developed a coordinated
exercise program (group-mediated cognitive behav-
ioral therapy) that includes weekly group sessions run
by a trained facil itato r In a rando mized controlled
trial of 194 patients subjects in the intervention group
improved their 6-min walkingdistance peak treadmill
exercise performance and several measures of QOL
and accelerometer-measured physical activity (46)
In addition after 6 months the intervention group
gained self-ef 1047297cacy satisfaction with functioning
pain acceptance and social functioning and these
bene1047297ts weresustained at the 12-monthendpoint (47)
At 12 months fewer treated patients experienced
mobility loss and treated patients also improved in
walking velocity and QOL (48)
It is apparent that many of the exercise methods
discussed are effective in improving walking distance
with less discomfort and improved QOL however
they all require resources that are not available in
many communities especially those in the lowest
socioeconomic class Although a simple recommen-
dation between the physician and the patient to exer-
cise is usually ineffective the physician can provide
a comprehensive exercise prescription (Table 1) on
how to structure a home exercise program (5051)
This is not a 1-time recommendation but an ongoing
discussion between the physician and the patient
in an attempt to change patient behavior Patients
who are compliant with such a program often experi-
ence considerable improvement in walking distance

THERAPY ARE WE ASKING THE RIGHT QUESTIONS
Several studies have compared an SE program to
revascula ri za ti on i n p atients wi th PAD a nd
exercise-limiting claudication (5253) G iven t he
tremendous expansion and effectiveness of endovas-
cular treatments for symptomatic PAD as well as
patient reluctance to enter an exercise-lifestyle treat-
ment program (as discussed previously) the most
prudent approach would be to include both modalities
in the treatment plan exercise and revascularization
In fact both exercise training and revascularizationcan greatly improve patient exercise performance

and QOL but by very different mechanisms Revascu-
larization primarily improves exercise blood 1047298ow
whereas exercise training does not (29) In contrast
exercise training induces a variety of adaptive re-
sponses including improved skeletal muscle mito-
chondrial oxidative metabolismimproved endothelialfunction and more ef 1047297cient biomechanics of walking
Thus the obvious ldquo bestrdquo treatment strategy would
appear to be the combined program utilizing endo-
vascular revascularization and an optimal home-based
and long-term exercise program This hypothesis
was initially tested more than 25 years ago and the
combination of bypass surgery and exercise training
was superior to either treatment alone (54)
The CLEVER (Claudication Exercise Versus Endo-
luminal Revascularization) study was an important
and well-designed comparative effectiveness trial
that compared the outcomes for stenting of aortoiliacdisease with SE on a background of optimal medical
therapy in both groups (52) At the initial 6-month
follow up the primary endpoint of peak walking
time on a graded treadmill test was signi1047297cantly
improved in both the exercise and stent groups
compared with optimal medical management but the
peak walking time was signi1047297cantly higher in the
exercise group than in the stent group (52) The sec-
ondary endpoints were changes in responses to QOL
questionnaires Both of these patient-reported out-
comes were improved with exercise or stenting over
optimal medical management however improve-
ments tended to be greater in the stenting group The
same endpoints were measured at 18 months of
follow-up (55) In 79 of 119 patients who completed
the study improvements in treadmill peak walking
time remained for both the exercise and stenting
groups over optimal medical therapy but the differ-
ences in peak walking time between the exercise and
stenting groups were no longer statistically signi1047297-
cant Improved patient-reported outcomes remained
for both the exercise and stent groups
CLEVER clearly established the independent long-
term and broad-based bene1047297ts of both exercise
training and stent revascularization in symptomatic
PAD Similar to many such trials of the nearly 1000
patients evaluated only 11 were randomized and
fewer were available for 18-month follow-up Unfor-
tunately the arm of CLEVER that would have tested
the combination of exercise plus stenting was drop-
ped because of poor enrollment
In the recently published ERASE (Endovascular
Revascularization and Supervised Exercise) trial
106 patients were randomized to both endovascular
therapy and SE and 106 patients to SE alone (56) After
1 year the combination group had greater improve-
ment in maximum walking distance (MWD) and
health-related QOL scores than the group randomized
to SE alone however both groups demonstrated
dramatic improvement in MWD pain-free walking
distance and QOL The supervised exercise group
increased MWD from 285 m to 1240 m for animprovement of 955 m The combination group
increased MWD from 264 m to 1501 m for an
improvement of 1237 m This study illustrates
2 important points 1) the combinationof endovascular
therapy and SE is the most effective therapy for many
patients with claudication and 2) even the group
randomized to SE alone showed marked improvement
in MWD pain-free walking distance and QOL (56)
The cost of therapy must also be considered when
planning a particular strategy to treat symptomatic
PAD In a single-center Dutch randomized trial
endovascular revascularization had similar bene1047297t but highe r total mean cumula tive costs per patie nt
T A B L E 1 A Practical Home Exercise Program for Patients
With PAD
Frequency
3-5 days per week
Modality
Treadmill (this program can be adapted for walking outside)
Method
1 Begin at 2 mph and a grade of 0 (1047298at)
2 Try not to hold onto the treadmill Use the side panels for balanceonly
3 Stop the treadmill completely when pain is 3ndash4 on claudicationdiscomfort scale
4 When the discomfort has ceased resume exercise at the sameintensity
5 Repeat restexercise cycles
6 Progress to a higher workload when you can walk for 8 minwithout having to stop for leg symptoms
a) Increase speed by 02 mph each time you can walk for 8 min
b) Once you are able to walk at 34 mph or reach a speed at whichyou can no longer keep up begin increasing the grade by 1
Duration
The total exercise period including rest periods should equal45 min per day
Tips for success
1 Do not continue walking past 3ndash4 on claudication paindiscomfortscale This way the paindiscomfort should go away in 2ndash5 min If you walk until you are in severe pain you will build up lactic acidin your muscles and it will take much longer for the pain to goaway
2 When at 3ndash4 on paindiscomfort scale stop walking completelyDo not slow down but stop and stand on the treadmill until thediscomfort is gone
This works if you do it Not only will this improve your walkingperformance decrease your discomfort and improve your
quality of life this type of program is also bene1047297cial for yourheart blood pressure and lipid (cholesterol and triglyceride)levels

compared with a hospital-based exercise program
(57) Another study from a Dutch health-care databaseof 4954 patients demonstrated that a stepped
approach of exercise therapy followed by endovas-
cular revascularization was more cost-effective than
revascularization only (58)
Thus future studies should address not only the
clinical bene1047297ts but also the effectiveness of the
combination of an exercise program and limb revas-
cularization In this context effectiveness pertains to
the ability of a treatment program to be utilized by a
majority of appropriate patients in a community and
to achieve high adherence to the program as well as
that the desired improvements in functional out-comes are obtained
OPTIMAL MEDICAL THERAPY FOR
PATIENTS WITH PAD
Medical therapy for PAD should address treatment for
limb-related outcomes (improve claudication symp-
toms and prevent CLI and amputation) and treatment
to prevent major adverse cardiovascular events
(MACE myocardial infarction stroke and cardio-
vascular death) (Central Illustration)
Despite the recommendations from societal
guidelines on the management of patients with PAD(2) these patients continue to be undertreated
compared with patients with CAD (859) Adherence
to these guidelines in real-world practice is associatedwith improved outcomes (Figure 1) which empha-
sizes the bene1047297t of multifactorial risk reduction in
this high-risk population (12) Performance measures
for PAD will help improve quality of care and may be
incorporated into future quality metrics (60)
SMOKING CESSATION
Smoking is a major risk factor for the developmentand
progression of PAD A multidisciplinary approach to
smoking cessation should be used including group-
based programs and cognit ive beha viora l therapy
A recent study evaluated the association betweensuccessful quitting after endovascular intervention
and long-term outcomes (61) Among 739 patients
undergoing lower-extremity angiography 28 were
active smokers at the time of endovascular interven-
tion In the subsequent year 30 of active smokers
successfully quit Those who remained off tobacco
had signi1047297cantly lower 5-year mortality (14 vs 31)
and improved amputation-free survival (81 vs
60) Discontinuation of smoking is the most
important lifestyle modi1047297cation in preventing CLI
amputation and MACE in patients with PAD This
needs to be conveyed to the patient in an empatheticand nonjudgmental way during every of 1047297ce visit The

VAPOR (Vascular Physician Offer and Report) trial is
currently evaluating methods to improve physician-
patient interactions to encourage patients with PAD
to abstain from smoking (62)
PHARMACOTHERAPY TO IMPROVE
CLAUDICATION SYMPTOMS
Cilostazol is a type III phosphodiesterase inhibitorwith a number of properties but the mechanism by
which cilostazol improves claudication is not known
(63) A pooled analysis of all of the randomized
trials shows an improvement in absolute claudica-
tion distance of approximately 50 compared with
placebo (64) Although cilostazol appears to be safe
for long-term administration adherence is low (gt60
discontinuation at 3 years) because of adverse effects
including headache palpitations and diarrhea (65)
Because of its mechanistic similarity to other type III
phosphodiesterase inhibitors such as milrinone cil-
ostazol is contraindicated in patients with a history of
heart failure The optimal dose of cilostazol is 100 mg
twice daily and it may take up to 4 months to derive
maximum bene1047297t from this drug (63)
Pentoxifylline is rarely used today to treat claudi-
cation because of a lack of ef 1047297cacy compared with
cilostazol Naftidrofuryl is a 5-HT2 antagonist that is
approved in Europe In a pooled analysis involving
888 patients randomized to naftidrofuryl there was a
26 increase in pain-free walking compared with
placebo (66) It is not available for use in the United
States
ACEIs
ACEIs are associated with a signi1047297cant reduction in
MACE among patients with PAD These data are
derived primarily from the HOPE (Heart Outcomes
Prevention Evaluation) trial which randomized 9297
high-risk patients with vascular disease or diabetes
plus 1 other risk factor to ramipril 10 mg daily
or placebo Among these 1966 patients with PAD
(423) were randomized to ramipril and 2085
(448) to placebo The primary outcome (myocardial
infarction stroke cardiovascular death) occurred in
143 of those without PAD versus 220 of those
with PAD (67) In the 5231 patients without PAD the
primary outcome was observed in 126 in the ram-
ipril group and 149 in the placebo arm In those with
an ABI lt06the primary outcome occurred in 164 in
the ramipril arm versus 22 in the placebo arm Thecardiovascular bene1047297t of ramipril applies to patients
with both asymptomatic and symptomatic PAD across
a broad range of ABI values (68) Similar results have
also been observed with telmisartan which suggests a
possible class effect of ACEIangiotensin receptor
blockade among patients with PAD (6970)
STATINS
High-intensity statin medications are recommended
for a ll pa ti ents with PAD on the basis of the
most recent American College of Cardiology (ACC)American Heart Association (AHA) guidelines which

emphasize cardiovascular risk over low-density lipo-
protein targets (71) The majority of the data in sup-
port of statin use in patients with PAD are derived
from subset analysis of larger clinical trials The
Medical Research CouncilBritish Heart Foundationrsquos
Heart Protection Study randomized 20536 high-risk
patients to simvastatin 40 mg daily or placebo (72)
All-cause mortality occurred in 129 of patients
randomized to simvastatin and 147 randomized to
placebo (22 relative risk reduction p frac14 00003)
Observational studies have also con1047297rmed the car-
diovascular and overall mortality bene1047297t of statins
among patients with more advanced PAD including
CLI (73)
Recent data suggest that statin use is also associ-
ated with a reduction in adverse limb outcomes
including amputation In the REACH (Reduction of
Atherothrombosis for Continued Health) registry
statin therapy was associated with a signi1047297cant
reduction in the combined endpoint of worsening
claudication new CLI new revascularization or
amputation (74) The absolute 4-year event rates were
220 versus 262 which emphasizes the highrate of
adverse limb events among patients with symptom-
atic PAD Importantly statin therapy was also associ-
ated with a signi1047297cant reduction in 4-year rates of
ischemic amputation (38 vs 56) In an analysis of
Medicare claims data of patients undergoing lower-
extremity revascularization statin use was associ-
ated with lower rates of amputation at 30 days
90 days and 1 year (75) Single-center observational
data among patients with CLI suggest that statin
therapy is also associated with improved 1-year rates
of primary patency secondary patency and improved
limb salvage after endovascular intervention (73)
Patients with PAD should be prescribed a high-
intensity statin to reduce the risk of cardiovascular
events In most studies the rates of statin prescrip-
tion were lt75 which emphasizes the importance of
maximizing medical therapy among this high-risk
group of patients with advanced atheroscleroticdisease (59)
ANTIPLATELET THERAPY
ASPIRIN Aspirin has been a mainstay of drug ther-
apy among patients with PAD however the data
supporting aspirin use in patients with PAD have not
been well subst antia ted (7677)
Recent studies investigating the bene1047297t of aspirin
among patients with asymptomatic PAD have yielded
negative results Both the POPADAD (Prevention of
Progression of Arterial Disease and Diabetes) trial and
the AAA (Aspirin for Asymptomatic Atherosclerosis)
trial compared low-dose aspirin with placebo in
patients with a low ABI Neither study demonstrated
a reduction in fatal and nonfatal cardiovascular
events or revascularization with aspirin mono-
therapy although both notably included low-risk
patients with borderline ABI (099 in POPADAD
and 095 in AAA) (7778)
Consistent with these results a meta-analysis
speci1047297cally examined aspirin for PAD in 18 trials
involving 5269 patients In patients taking aspirin
monotherapy there was a nonsigni1047297cant reduction
in cardiovascular events (absolute event rate 82
vs 96 relative risk 075 95 con1047297dence inter-
val [CI] 048 to 118) however there was a sig-
ni1047297cant reduction in nonfatal stroke (HR 064 95
CI 042 to 099 p frac14 004) (76) In the last iteration
of the PAD guidelines (2) aspirin was a Class I
Level of Evidence A recommendation among pa-
tients with symptomatic PAD a Class IIa recom-
mendation among patients with asymptomatic PAD
and an ABI lt090 and a Class IIb indication among
asymptomatic patients with an ABI of 090 to 099
(2) Some of these recommendations may change in
the upcoming revision of the ACCAHA PAD prac-
tice guidelines
CLOPIDOGREL AND
DUAL-ANTIPLATELET THERAPY
Clopidogrel is indicated as an alternative to aspirin
for antiplatelet monotherapy among patients with
PAD although recent studies suggest that lt20 of
patients with PAD are prescribed clopidogrel in clin-
ical practice (79) The data supporting clopidogrel use
are primarily based on the CAPRIE (Clopidogrel
Versus Aspirin in Patients at Risk of Ischaemic
Events) study in which clopidogrel monotherapy was
associated with a small bene1047297t compared with aspirin
325 mg daily in the overall population but there was a
238 relative risk reduction among the subgroup of
patients with symptomatic PAD (n frac14 6452 absolute
event rate 37 vs 49 per year) (80)
Dual-antiplatelet therapy (DAPT) with low-dose
aspirin (75 to 162 mg daily) and clopidogrel 75 mg
daily was studied in the CHARISMA (Clopidogrel for
High Atherothrombotic Risk and Ischemic Stabiliza-
tion Management and Avoidance) trial which
included patients at high risk for atherothrombotic
events The overall results of this trial were not sig-
ni1047297cant although in subgroup analyses there was a
bene1047297t of DAPT among patients with symptomatic
atherothrombosis (81) In an analysis of the 3096 pa-
tients in the trial with PAD DAPT was associated with
a lower rate of myocardial infarction (23 vs 37

ization for ischemic events (165 vs 201 HR 081
95 CI 068 to 095 p frac14 0011) but not the overall
composite primary endpoint (82) There was no dif-
ference between the groups in moderate severe or
fatal bleeding but there was an increase in minor
bleed ing i n th e DAPT group
In a recent propensity-matched observational
study among patients undergoing endovascular
intervention there was a signi1047297cant reduction in
MACE among patients taking DAPT (adjusted HR
065 95 CI 044 to 096 p frac14 003) compared with
those taking aspirin monotherapy (83) The discor-
dant 1047297ndings between this study and the CHARISMA
trial may be explained by inclusion of a cohort
with more advanced atherosclerotic disease under-
going endovascular intervention including gt50 of
patients with CLI
The CASPAR (Clopidogrel and Acetylsalicylic Acid
in Bypass Surgery for Peripheral Arterial Disease) trial
studied DAPT versus aspirin 75 to 100 mg daily among
patients undergoing below-knee surgical bypass for
treatment of CLI (84) The primary endpoint of death
major amputation index-graft occlusion or revascu-
larization was not different for DAPT versus
acetylsalicylic acid (ASA) monotherapy In a pre-
speci1047297ed subgroup analysis there was a signi1047297cant
bene1047297t of DAPT in patients treated with prosthetic
grafts (HR 065 95 CI 045 to 095 p frac14 0025) but
not in those treated with vein grafts A similar trial
the CAMPER study (Clopidogrel and Aspirin in the
Management of peripheral Endovascular Revascular-
ization) tested DAPT versus aspirin in patients un-
dergoing infrainguinal endovascular therapy The
study was never completed because of poor enroll-
ment (doctors would not randomize patients to ASA
alone) continued funding could not be justi1047297ed
DAPT is often prescribed after endovascular inter-
vention although the data supporting duration of
DAPTare sparseIn practice most physicians prescribe
DAPTfor a time periodrangingfrom1 to3 monthspost-intervention The ASPIRE-PAD study (Antiplatelet
Strategy for Peripheral Arterial Interventions for
Revascularization of Lower Extremities) is currently
evaluating comparative outcomes of 1 versus 12
months of DAPT after endovascular intervention (85)
VORAPAXAR
Thrombin acts through platelets via a unique mecha-
nism binding of the protease activating receptor-1
(PAR-1) a G protein-coupled receptor expressed on
the platelet surface leads to receptor activation
and increased intracellular Ca2thorn cyclic adenosine
monophosphate (cAMP) levels subsequently decrease
which leads to increased platelet aggregation and
releaseof further activatingfactors Vorapaxar inhibits
PAR-1 thereby signi1047297cantly reducing thrombin-
mediated platelet activation
T he T RA 2P-TIMI 50 trial (Thrombin Receptor
Antagonist for Secondary PreventionndashThrombolysis
in Myocardial Infarction Study Group) studied vor-
apaxar sulfate 25 mg daily versus placebo (ASA and
or clopidogrel therapy at the investigatorsrsquo discre-
tion) among 26449 patients with a recent myocardial
infarction recent ischemic stroke or symptomatic
PAD At 3 years there was a signi1047297cant reduction in
the primary endpoint of MACE (absolute event rates
93 vs 105 HR 087 95 CI 080 to 094
p lt 0001) (79) After 2 years the data and safety
monitoring board recommended stopping the study
drug in the patient subgroup entered with prior
ischemic stroke because of an increased risk of
intracranial hemorrhage Among the 3787 patients
with PAD the majority were treated with aspirin
monotherapy plus vorapaxar or placebo The reduc-
tion in MACE was not statistically signi1047297cant in those
assigned to vorapaxar (absolute event rates 113 vs
119 HR 094 95 CI 078 to 114) Similarly
negative results were observed among patients with
PAD who were enrolled in the TRACER (Thrombin
Receptor Antagonist for Clinical Event Reduction in
Acute Coronary Syndrome) trial (86) Additionally
vorapaxar is associated with a signi1047297cantly increased
risk of major bleeding However in both of these
trials there were relatively few MACE in the PAD
subgroup The PAD group was underpowered to draw
any conclusions on ef 1047297cacy
Pre-speci1047297ed analysis of limb-related outcomes in
the TRA 2P-TIMI 50 trial demonstrated that patients
assigned to vorapaxar had signi1047297cantly reduced rates
of acute limb ischemia (23 vs 39 HR 058 95
CI 039 to 086 p frac14 0006) as well as peripheral
artery revascularization (184 vs 222 HR 084
95 CI 073 to 097 p frac14 0017) during the 3-yearfollow-up (Figure 2) (87) These ef 1047297cacy endpoints
must be balanced by a signi1047297cantly increased rate of
major bleeding among patients prescribed vorapaxar
Further research into the mechanism by which
vorapaxar led to improved limb outcomes is required
to fully understand these effects
CELL-BASED AND ANGIOGENIC THERAPIES
Modulation and enhancement of lower-extremity
blood 1047298ow via angiogenesis arteriogenesis or vas-
culogenesis could provide a promising breakthrough
therapy for patients with PAD (88) Additionally

there has been much interest in the use of stem cellndash
derived endothelial cells or modi1047297cation of resident
stem cells (89) Potential bene1047297ts of these therapies
include improved wound healing and limb salvage
among patients with CLI as well as improved clau-
dication distance To date numerous cell-based and
angiogenic therapies have been tested and despite
promising results in early clinical trials none of these
agents have shown bene1047297t in larger trials
ONGOING CLINICAL TRIALS
There are currently 2 clinical trials studying novel
antiplatelet and anticoagulant agents to reduce MACE
and potentially modify limb-related outcomes
EUCLID (Study Comparing Cardiovascular Effects of
Ticagrelor and Clopidogrel in Patients With Periph-eral Artery Disease) is a randomized blinded double-
dummy trial comparing ticagrelor 90 mg twice daily
to clopidogrel monotherapy among 13500 patients
with PAD (90) All patients are tested for clopidogrel
resistance before randomization The primary
endpoint is a composite of MACE and results are
expected in late 2016 The COMPASS (Rivaroxaban for
the Prevention of Major Cardiovascular Events in
Coronary or Peripheral Artery Disease) trial is evalu-
ating low-dose rivaroxaban alone versus placebo
aspirin alone or rivaroxaban and aspirin among
21400 patients with a history of myocardial infarc-tion or PAD the primary endpoint of this trial is a
composite of MACE (91)
ENDOVASCULAR THERAPY
Endovascular revascularization plays a key role in the
management of patients with PAD Patients with sta-
ble cl audication have a low ris k of lim b loss but may be
severely limited by their symptoms In most circum-
stances patients with claudication should be offered a
trial of cilostazol and an exercise program as initial
therapy If the patient is not satis1047297ed after a trial of
medical therapy endovascular revascularization can be consi dere d Patie nts with CLI require more urgent
revascularization because of an increased riskof tissue
loss and amputation as well as an extremely high risk
of cardiovascular events (92)
There are 2 well-established classi1047297cation schemes
to describe the severity of PAD The 1047297rst is a func-
tional assessment (Fontaine or Rutherford classi1047297ca-
tion [RC]) (Table 2) and the second is an anatomic
lesion classi1047297cation (Trans-Atlantic Inter-Society
Consensus [TASC]) (Table 3) (45) In addition there
has been recent interest in the angiosome concept in
helping to in1047298uence optimal revascularization stra-tegies for limb salvage (93) An angiosome is an
anatomic unit of tissue (consisting of skin subcu-
taneous tissue fascia muscle and bone) that is fed
by a source arte ry and drai ned by speci1047297c veins
If the patient is a candidate for either endovascular
or open surgery the less invasive option (ie an
endovascular-1047297rst strategy) is the current standard of
care The selection of a complex lesion (TASC D) for
endovascular therapy will vary with the skill and
experience of the interventionalist The goal in
treating a patient who has functional impairment
because of claudi cation is dura ble relief of symptoms
In patients with CLI and a threatened limb or tissueloss the goal is rapid reperfusion of the ischemic

AORTOILIAC OCCLUSIVE DISEASE
There has been a practice shift over the past 25 years
as the treatment of aortoiliac disease transitioned
from open surgery with aortobiiliac or aortobifemoral
bypass to endovascular trea tment s for comple x and
diffuse disease (TASC D) This preference for less
invasive therapy is evidence based and driven by
shorter length of stay (or treatment as an outpatient
entirely) and lower periprocedural morbidity and
mortality rates while achieving comparable patency
rates (4- to 5-year primary patency of 60 to 86
with secondary patency rates of 80 to 98) (94)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) In 2011 the European Society of Car-
diology (ESC) (3) and ACCAHA PAD guidelines (2)
recommended an endovascular-1047297rst approach for
aortoiliac lesions recommended that borderline
lesions be assessed with hemodynamic gradients and
supported primary stent placement in the aortoiliac
arteries (Table 4) The current expert consensus
document from the Society for Cardiac Angiography
and Interventions (SCAI) on appropriate use criteria
(AUC) for aortoiliac intervention are similar to the
current guidelines (95)

Treatment of TASC A B C and D Iliac Lesions) re-
ported 100 technical success in 325 patients with
aortoiliac lesions with a 24-month primary patency
rate of 879 (96) Neither TASC category nor lesion
length was predictive of restenosis These data
further support the endovascular-1047297rst strategy
regardless of TASC classi1047297cation and take into
consideration the evolution of devices (ie re-entry
catheters crossing devices and stents) which
improve success rates for the most complex lesions
COMMON FEMORAL DISEASE
Patients with common femoral artery (CFA) disease
are particularly symptomatic because the obstruction
not only occurs proximal to the super1047297cial femoral
artery (SFA) but also proximal to the deep femoralartery (profunda femoris) which is the major collat-
eral artery supplying blood to the lower limb when
there is SFA obstruction Traditionally common
femoral endarterectomy has been the CFA revascu-
larization procedure of choice (23) although
advances in endovascular therapy have shown some
promising results (97) A review of the National Sur-
gical Quality Improvement Program database for 2005
to 2010 found a combined mortality and morbidity
rate of 15 for common femoral endarterectomy
which was higher than expected (98) Patients
requiring CFA revascularization who are at increasedsurgical risk may be considered for less invasive
endovascular options
FEMORAL-POPLITEAL DISEASE
This segment begins at the bifurcation of the CFA into
the SFA and the deep femoral (profunda femoris)
artery The SFA is subject to 1047298exion elongation
compression and torsion unlike any other lower-
extremity artery This complexity leads to many
challenges for endovascular technology but despite
this an endovascular-1047297rst approach is currently thestandard of therapy for the majority of lesions
becau se of the very high proce dural success rate and
low risk (3) Some of the most lengthy and complex
lesions (TASC D) are more approachable because of
the re-entry and crossing devices more experienced
operators drug-eluting stents (DES) (99100) and
drug-coated balloons (DCBs) (101ndash107) that promise
improved long-term patency for patients with clau-
dication (99100103105)

(2011) PAD guidelines and the AUC documentfrom the SCAI recommend revascularization in
femoral-popliteal lesions for patients with CLI or for
patients with claudication who have had a suboptimal
r espon se to a tr ial of e xer cise (Tab le 5) An
endovascular-1047297rst approach is recommended for
TASC A through C lesions and is a reasonable option
for TASC D lesions depending on the experience of
the operator the patientrsquos comorbidities and proce-
dure safety (Table 5) (2395)
The 2 guidelines are in con1047298ict over the use of
primary stent placement in the femoral-popliteal ar-
teries with the ACCAHA guideline giving it a Class III
recommendation (do not do) and the ESC guideline
making primary femoral stenting reasonable 1047297rst-line
therapy (Class IIa) for intermediate-length lesions
(108109) The current evidence from several ran-
domized controlled trials supports primary stenting
in intermediate-length femoral stenoses and occlu-
sions (108ndash110) The soon-to-be-published updatedACCAHA guidelines will readdress this issue In
current practice the standard is to primarily stent
intermediate to long SFA lesions
The ACCAHA guideline broadly lump stents
togetherwith atherectomy devicescryotherapy laser
and cutting balloons stating they may be useful as
salvage therapy (Class IIa) but also stating that their
effectiveness remains to proven (Class IIb) Stents
should be removed from this group because their
effectiveness has been established in intermediate-
length femoral lesions Other than the use of the cut-
ting balloon and rotational atherectomy in lesions thatare resistant to dilation there is no comparative

evidence suggesting that the more expensive athe-
rectomy devices cryoplasty or laser angioplasty
should be preferred over conventional therapy
(percutaneous transluminal angioplasty [PTA] and
bare- metal stents [BMS] ) The ESC guideline disti n-
guishes bare-metal self-expanding stents from
adjunctive devices such as atherectomy devices cit-
i ng the p roven bene1047297t of BMS over PTA in
intermediate-length femoral-popliteal lesions
CLINICAL TRIAL UPDATE Three randomized controlledtrials of self-expanding BMS compared with PTA have
shown that the advantage for primary stenting is
related to lesion length For relatively discrete lesions
(mean 45 mm) (110) there was no advantage for pri-
mary stent placement however 2 other trials
(108109) with longer lesions (gt70 mm) showed a
signi1047297cant patency and functional bene1047297t for primary
femoral-popliteal BMS (Figure 3 Table 6) The proce-
dural success rate of endovascular therapy in
femoral-popliteal lesions is very high but in stable
limb ischemia durable patency remains a barrier
Cilostazol has been shown to reduce 1-year restenosis by more than one-half (20 vs 49 p frac14 00001) in
intermediate-length (128 mm) femoral lesions treated
with self-expanding BMS (114) These results need to
be con1047297rmed before this can be recommended as
standard therapy
Recent randomized controlled trials demonstrating
bene1047297t f or DE S (99100) DC B (103105106) and
covered stents (115ndash117) in femoral-popliteal arteries
will likely result in a change in the guidelines and
indications (Table 6 Figure 3)
There hasbeen some enthusiasm for self-expanding
covered (expanded polytetra1047298uoroethylene) stent
grafts in complex or lengthy femoral-popliteal seg-
ments Two randomized trials comparing covered
stents to BMS had divergent results One showed a
bene1047297t for 2-year primary patency but no difference in
target-lesion revascularization (TLR) or clinical out-
comes (116) whereas the other in longer (gt8 cm) le-
sions found no difference for primary patency (115ndash
117) When covered stents were compared with
above-the-knee femoral bypass with synthetic graft
material in a broad range of SFA lesion types (TASC A
thru D) no difference was found in the 4-year primary
patency between the 2 options (118)
The Zilver paclitaxel-eluting self-expanding DES
was superior to PTA in a randomized femoral-
popliteal trial with 1-year patency rates of 831 for
primary DES and 328 for PTA (p lt 0001) (Figure 3
Table 6) (99) There was also a 1-year patency
advantage for provisional DES after failed PTA
(899) compared with provisional BMS (730
p frac14 001) The bene1047297t was sustained at 2 years with
primary patency for the DES (748) signi1047297cantly
better t han PTA (265 p lt 001) (100) To date there
has been no head-to-head comparison of primary DES
to either BMS or DCB in femoral-popliteal arteries
but Zelle r et al (104) published a propensity scorendash
based compar ison of DES and DCB in conse cutive
patients with TASC C and D long (gt10 cm) lesions and
found no signi1047297cant differences in 1-year patency
(Figure 3 Table 6)
DCBs offer the promise of improved patency with areduced need for stents This is particularly important
in the dynamic environment of the super1047297cial femoral
and popliteal arteries where mechanical fatigue may
lead to stent fracture and increased risk of in-stent
restenosis Each DCB is unique with respect to the
paclitaxel dose (varying from 2 to 35 mgmm2) the
carrier molecule (excipient) the balloon material and
the coating technology used Superiority for paclitaxel
DCB over PTA was 1047297rst reported in 2008 (101102)
(Figure 3 Table 6) Subsequently new DCBs have
emerged including the INPACT (105106111113) and
the Lutonix (103106) balloons both of which showedclinical superiority to PTA in femoral-popliteal lesions

TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

Despite the increased prevalence over the past 20

undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

therefore be elusive unless patients are
identi1047297ed with targeted diagnostic testing
(ie ankle-brachial index [ABI]) (21) T he
treatment of underlying cardiovascular risk
factors results in reduced morbidity and
mortality for patients with PAD although this
population continues to be under-recognized
and undertreated for their cardiovascular risk
(28) Among 7458 participants with PAD in
the 1999 to 2004 NHANES (National Health
and Nutrition Examination Survey) data only
305 of subjects were taking statins 249
were taking angiotensin-converting enzyme
inhibitors (ACEI) or angiotensin receptor
blockers and 358 were admini stered
aspirin Among patients with PAD (and no
other clinical cardiovascular disease) use of
multiple preventive therapies was associated
with a 65 lower all-cause mortality (hazard ratio
[HR] 035 p frac14 002) (8)
The diagnosis of PAD can be made using the ABI
Using a handheld continuous-wave Doppler device
the ABI can be measured by taking the higher of the
2 systolic pressures in the dorsalis pedis and posterior
tibial artery in each leg and dividing by the higher of
the brachial artery systolic blood pressures in each
arm An abnormal ABI is diagnostic for PAD (21)
A normal ABI is between 100 and 140 An ABI 090
demonstrates 90 sensitivity and 95 speci1047297city for
PAD and is the accepted threshold for diagnosis (221)
Values between 091 and 100 are considered border-
line however the cardiovascular event rate for an ABI
in this range is increased by 10 to 20 (21) At levels
gt140 the identi1047297cation of PAD is not accurate
because of the presence of arterial calci1047297cation and
noncompressibility of the blood vessels a 1047297nding
frequently encountered in the very elderly and in
those with diabetes and chronic kidney diseaseIn this
setting the toe-brachial index is used and considered
abnormal when lt070 (421) There is a strong and
consistent relationship between an abnormal ABI andthe presence of coronary or cerebrovascular disease
(51622) In addition the ABI is a predictor of cardio-
vascular morbidity and mortality independent of
clinical risk prediction scores such as the Framingham
Risk Score and other surrogate markers of systemic
atherosclerosis suchas the coronary calciumscore and
carotid artery intimal-medial thickness (23) There is
alsoa higher cardiovascular event ratein patientswith
PAD (even in asymptomatic patients) with known
coronary artery disease (CAD) (24)
Several consensus documents and practice guide-
lines recommend screening for the presence of PADusing the ABI in patients $65 years old or those who
are $50 years of age with a history of diabetes or
smoking (2ndash4925) The goal is to identify and treat
patients with increased cardiovascular risk Despite
these recommendations and the fact that nearly one-
half of all PAD patients are asymptomatic there is no
reimbursement for the performance of an ABI in the
absence of clinical symptoms of PAD Alternative
diagnostic methods for PAD are beyond the scope of
this review
Serum biomarkers have been used for risk predic-
tion and the detection of PAD (26) A combined
biomarker pro1047297le that includes fasting glucose high-
sensitivity C-reactive protein b2-microglobulin and
cystatin C demonstrated ef 1047297cacy in the identi1047297cation
of PAD and reclassi1047297cation of cardiovascular risk
assessment by Framingham Risk Score in patients who
would have otherwise been misidenti1047297ed (27) The
BRAVO (Biomarker Risk Assessment in Vulnerable
Outcomes) study evaluated 595 patients with PAD and
followed them for 3 years The primary outcome was
ischemic heart disease events (myocardial infarction
unstable angina or ischemic heart disease death) Of
the 50 participants who had an event the D-dimer was
higher 2 months before the event than the values 10
months 12 months 16 months 20 months 26 months
and 32 months before the event There was no change
in the serum amyloid A or CRP 2 months before an
event (28) Although there is a clear association
betwe en various biomar kers and PAD the overall
clinical value related to patient outcomes remains
unclear and thus there is no clinical bene1047297t in
measuring biomarkers at this time
THE ROLE OF EXERCISE
Patients with PAD have a profound limitation in
exercise performance that is related to a complex
pathophysiology (29) Although reduced exercise
performance is a hallmark of PAD the symptomatic
manifestations are quite varied as described previ-
ously (30) Not surprisingly patients with claudica-tion slow their walking pace and often avoid walking
altogether Thus patients with PAD present with a
complex array of symptoms health beliefs and
exercise limitations in their daily lives (3132) These
perceptions and attitudes must be addressed if a
treatment plan is to be successful
The overall goal in treating the exercise limitation
from PAD is to improve exercise performance with a
corollary improvement in quality of life (QOL) and
functional status In this regard treatments that
improve treadmill exercise performance 6-min
walking distance and patient-related QOL can serveas a basis for obtaining regulatory approval of a

claudication therapy In contrast changes in limb
hemodynamics such as an improvement in the ABI or
imaging after a successful revascularization serve
only as surrogate measures of clinical bene1047297t
Exercise training has been a mainstay of treatment
for symptomatic PAD with a well-established bene1047297t
after a typical 12-week exercise training program
(3334) Exercise training directly modi1047297es several
pathophysiological mechanisms in PAD including
improved skeletal muscle metabolism endothelial
function and gait biomechanics (35)
SUPERVISED EXERCISE TRAINING I MPROVES MORBIDITY
AND MORTALITY IN PAD Individual single-site studies
and a meta-analysis of those studies demonstrate that
a 12-week intervention of supervised exercise (SE)
improves exercise performance and QOL in PAD (34)Supervised exercise is also more effective than a
nonstructured community exercise program (36)
Physical activity in patients with PAD is associated
with decreased all-cause and cardiovascular mortality
(3738) Standardized supervised training methods
have been published previously (39)
On the basis of current evidence supervised
walking exercise gets a Class Ia recommendation and
unsupervised exercise a Class IIb recommendation
(2) Despite clear evidence of bene1047297t SE programs
have not been accepted by payers providers or
patients for a variety of reasons including questionsof long-term adherence and the bene1047297t of exercise as a
lifestyle intervention coupled with the desire by most
patients and vascular physicians for a more immedi-
ate approach to relieving claudication with endovas-
cular therapy (40) Therefore SE training programs
for claudication are very limited and not reimbursed
HOME-BASED EXERCISE DATA AND GENERALIZABILITY
OF THE FINDINGS The methodology to provide a
community (home)-based exercise intervention has
improved considerably over the past decade and
these exercise training methods have provided
encouraging resultsThe least resource-intensive home-based program
can employ education and behavioral interventions
that prepare patients for exercise training (41)
Notably adherence to a community program may be
poor without proper motivation and engagement
There are a number of new devices that monitor
the intensity and duration of an exercise session
performed in the home environment A pilot study
that used a program of training monitoring and
coaching had encouraging results in a subgroup of
subjects but was too small to de1047297nitively establish the
bene1047297ts of the interventions (42) Two larger trialsused a step activity monitor to record the duration
and intensity of the walking exercise to inform the
research staff and patient as to the patientrsquos exercise
prescription One randomized trial combined the
activity monitor with a home-based program that
used the principles of a hospital-based supervised
program (43) Adherence to the home program was
gt80 and the results on improvements in treadmill
exercise performance were comparable between
home and supervised programs A follow-up study
demonstrated similar results (44)
McDermott et al (45) have developed a coordinated
exercise program (group-mediated cognitive behav-
ioral therapy) that includes weekly group sessions run
by a trained facil itato r In a rando mized controlled
trial of 194 patients subjects in the intervention group
improved their 6-min walkingdistance peak treadmill
exercise performance and several measures of QOL
and accelerometer-measured physical activity (46)
In addition after 6 months the intervention group
gained self-ef 1047297cacy satisfaction with functioning
pain acceptance and social functioning and these
bene1047297ts weresustained at the 12-monthendpoint (47)
At 12 months fewer treated patients experienced
mobility loss and treated patients also improved in
walking velocity and QOL (48)
It is apparent that many of the exercise methods
discussed are effective in improving walking distance
with less discomfort and improved QOL however
they all require resources that are not available in
many communities especially those in the lowest
socioeconomic class Although a simple recommen-
dation between the physician and the patient to exer-
cise is usually ineffective the physician can provide
a comprehensive exercise prescription (Table 1) on
how to structure a home exercise program (5051)
This is not a 1-time recommendation but an ongoing
discussion between the physician and the patient
in an attempt to change patient behavior Patients
who are compliant with such a program often experi-
ence considerable improvement in walking distance

Several studies have compared an SE program to
revascula ri za ti on i n p atients wi th PAD a nd
exercise-limiting claudication (5253) G iven t he
tremendous expansion and effectiveness of endovas-
cular treatments for symptomatic PAD as well as
patient reluctance to enter an exercise-lifestyle treat-
ment program (as discussed previously) the most
prudent approach would be to include both modalities
in the treatment plan exercise and revascularization
In fact both exercise training and revascularizationcan greatly improve patient exercise performance

and QOL but by very different mechanisms Revascu-
larization primarily improves exercise blood 1047298ow
whereas exercise training does not (29) In contrast
exercise training induces a variety of adaptive re-
sponses including improved skeletal muscle mito-
chondrial oxidative metabolismimproved endothelialfunction and more ef 1047297cient biomechanics of walking
Thus the obvious ldquo bestrdquo treatment strategy would
appear to be the combined program utilizing endo-
vascular revascularization and an optimal home-based
and long-term exercise program This hypothesis
was initially tested more than 25 years ago and the
combination of bypass surgery and exercise training
was superior to either treatment alone (54)
The CLEVER (Claudication Exercise Versus Endo-
luminal Revascularization) study was an important
and well-designed comparative effectiveness trial
that compared the outcomes for stenting of aortoiliacdisease with SE on a background of optimal medical
therapy in both groups (52) At the initial 6-month
follow up the primary endpoint of peak walking
time on a graded treadmill test was signi1047297cantly
improved in both the exercise and stent groups
compared with optimal medical management but the
peak walking time was signi1047297cantly higher in the
exercise group than in the stent group (52) The sec-
ondary endpoints were changes in responses to QOL
questionnaires Both of these patient-reported out-
comes were improved with exercise or stenting over
optimal medical management however improve-
ments tended to be greater in the stenting group The
same endpoints were measured at 18 months of
follow-up (55) In 79 of 119 patients who completed
the study improvements in treadmill peak walking
time remained for both the exercise and stenting
groups over optimal medical therapy but the differ-
ences in peak walking time between the exercise and
stenting groups were no longer statistically signi1047297-
cant Improved patient-reported outcomes remained
for both the exercise and stent groups
CLEVER clearly established the independent long-
term and broad-based bene1047297ts of both exercise
training and stent revascularization in symptomatic
PAD Similar to many such trials of the nearly 1000
patients evaluated only 11 were randomized and
fewer were available for 18-month follow-up Unfor-
tunately the arm of CLEVER that would have tested
the combination of exercise plus stenting was drop-
ped because of poor enrollment
In the recently published ERASE (Endovascular
Revascularization and Supervised Exercise) trial
106 patients were randomized to both endovascular
therapy and SE and 106 patients to SE alone (56) After
1 year the combination group had greater improve-
ment in maximum walking distance (MWD) and
health-related QOL scores than the group randomized
to SE alone however both groups demonstrated
dramatic improvement in MWD pain-free walking
distance and QOL The supervised exercise group
increased MWD from 285 m to 1240 m for animprovement of 955 m The combination group
increased MWD from 264 m to 1501 m for an
improvement of 1237 m This study illustrates
2 important points 1) the combinationof endovascular
therapy and SE is the most effective therapy for many
patients with claudication and 2) even the group
randomized to SE alone showed marked improvement
in MWD pain-free walking distance and QOL (56)
The cost of therapy must also be considered when
planning a particular strategy to treat symptomatic
PAD In a single-center Dutch randomized trial
endovascular revascularization had similar bene1047297t but highe r total mean cumula tive costs per patie nt
T A B L E 1 A Practical Home Exercise Program for Patients
With PAD
Frequency
3-5 days per week
Modality
Treadmill (this program can be adapted for walking outside)
Method
1 Begin at 2 mph and a grade of 0 (1047298at)
2 Try not to hold onto the treadmill Use the side panels for balanceonly
3 Stop the treadmill completely when pain is 3ndash4 on claudicationdiscomfort scale
4 When the discomfort has ceased resume exercise at the sameintensity
5 Repeat restexercise cycles
6 Progress to a higher workload when you can walk for 8 minwithout having to stop for leg symptoms
a) Increase speed by 02 mph each time you can walk for 8 min
b) Once you are able to walk at 34 mph or reach a speed at whichyou can no longer keep up begin increasing the grade by 1
Duration
The total exercise period including rest periods should equal45 min per day
Tips for success
1 Do not continue walking past 3ndash4 on claudication paindiscomfortscale This way the paindiscomfort should go away in 2ndash5 min If you walk until you are in severe pain you will build up lactic acidin your muscles and it will take much longer for the pain to goaway
2 When at 3ndash4 on paindiscomfort scale stop walking completelyDo not slow down but stop and stand on the treadmill until thediscomfort is gone
This works if you do it Not only will this improve your walkingperformance decrease your discomfort and improve your
quality of life this type of program is also bene1047297cial for yourheart blood pressure and lipid (cholesterol and triglyceride)levels

compared with a hospital-based exercise program
(57) Another study from a Dutch health-care databaseof 4954 patients demonstrated that a stepped
approach of exercise therapy followed by endovas-
cular revascularization was more cost-effective than
revascularization only (58)
Thus future studies should address not only the
clinical bene1047297ts but also the effectiveness of the
combination of an exercise program and limb revas-
cularization In this context effectiveness pertains to
the ability of a treatment program to be utilized by a
majority of appropriate patients in a community and
to achieve high adherence to the program as well as
that the desired improvements in functional out-comes are obtained
OPTIMAL MEDICAL THERAPY FOR
PATIENTS WITH PAD
Medical therapy for PAD should address treatment for
limb-related outcomes (improve claudication symp-
toms and prevent CLI and amputation) and treatment
to prevent major adverse cardiovascular events
(MACE myocardial infarction stroke and cardio-
vascular death) (Central Illustration)
Despite the recommendations from societal
guidelines on the management of patients with PAD(2) these patients continue to be undertreated
compared with patients with CAD (859) Adherence
to these guidelines in real-world practice is associatedwith improved outcomes (Figure 1) which empha-
sizes the bene1047297t of multifactorial risk reduction in
this high-risk population (12) Performance measures
for PAD will help improve quality of care and may be
incorporated into future quality metrics (60)
SMOKING CESSATION
Smoking is a major risk factor for the developmentand
progression of PAD A multidisciplinary approach to
smoking cessation should be used including group-
based programs and cognit ive beha viora l therapy
A recent study evaluated the association betweensuccessful quitting after endovascular intervention
and long-term outcomes (61) Among 739 patients
undergoing lower-extremity angiography 28 were
active smokers at the time of endovascular interven-
tion In the subsequent year 30 of active smokers
successfully quit Those who remained off tobacco
had signi1047297cantly lower 5-year mortality (14 vs 31)
and improved amputation-free survival (81 vs
60) Discontinuation of smoking is the most
important lifestyle modi1047297cation in preventing CLI
amputation and MACE in patients with PAD This
needs to be conveyed to the patient in an empatheticand nonjudgmental way during every of 1047297ce visit The

PHARMACOTHERAPY TO IMPROVE
CLAUDICATION SYMPTOMS
Cilostazol is a type III phosphodiesterase inhibitorwith a number of properties but the mechanism by
which cilostazol improves claudication is not known
(63) A pooled analysis of all of the randomized
trials shows an improvement in absolute claudica-
tion distance of approximately 50 compared with
placebo (64) Although cilostazol appears to be safe
for long-term administration adherence is low (gt60
discontinuation at 3 years) because of adverse effects
including headache palpitations and diarrhea (65)
Because of its mechanistic similarity to other type III
phosphodiesterase inhibitors such as milrinone cil-
ostazol is contraindicated in patients with a history of
heart failure The optimal dose of cilostazol is 100 mg
twice daily and it may take up to 4 months to derive
maximum bene1047297t from this drug (63)
Pentoxifylline is rarely used today to treat claudi-
cation because of a lack of ef 1047297cacy compared with
cilostazol Naftidrofuryl is a 5-HT2 antagonist that is
approved in Europe In a pooled analysis involving
888 patients randomized to naftidrofuryl there was a
26 increase in pain-free walking compared with
placebo (66) It is not available for use in the United
States
ACEIs
ACEIs are associated with a signi1047297cant reduction in
MACE among patients with PAD These data are
derived primarily from the HOPE (Heart Outcomes
Prevention Evaluation) trial which randomized 9297
high-risk patients with vascular disease or diabetes
plus 1 other risk factor to ramipril 10 mg daily
or placebo Among these 1966 patients with PAD
(423) were randomized to ramipril and 2085
(448) to placebo The primary outcome (myocardial
infarction stroke cardiovascular death) occurred in
143 of those without PAD versus 220 of those
with PAD (67) In the 5231 patients without PAD the
primary outcome was observed in 126 in the ram-
ipril group and 149 in the placebo arm In those with
an ABI lt06the primary outcome occurred in 164 in
the ramipril arm versus 22 in the placebo arm Thecardiovascular bene1047297t of ramipril applies to patients
with both asymptomatic and symptomatic PAD across
a broad range of ABI values (68) Similar results have
also been observed with telmisartan which suggests a
possible class effect of ACEIangiotensin receptor
blockade among patients with PAD (6970)
STATINS
High-intensity statin medications are recommended

emphasize cardiovascular risk over low-density lipo-
protein targets (71) The majority of the data in sup-
port of statin use in patients with PAD are derived
from subset analysis of larger clinical trials The
Medical Research CouncilBritish Heart Foundationrsquos
Heart Protection Study randomized 20536 high-risk
patients to simvastatin 40 mg daily or placebo (72)
All-cause mortality occurred in 129 of patients
randomized to simvastatin and 147 randomized to
placebo (22 relative risk reduction p frac14 00003)
Observational studies have also con1047297rmed the car-
diovascular and overall mortality bene1047297t of statins
among patients with more advanced PAD including
CLI (73)
Recent data suggest that statin use is also associ-
ated with a reduction in adverse limb outcomes
including amputation In the REACH (Reduction of
Atherothrombosis for Continued Health) registry
statin therapy was associated with a signi1047297cant
reduction in the combined endpoint of worsening
claudication new CLI new revascularization or
amputation (74) The absolute 4-year event rates were
220 versus 262 which emphasizes the highrate of
adverse limb events among patients with symptom-
atic PAD Importantly statin therapy was also associ-
ated with a signi1047297cant reduction in 4-year rates of
ischemic amputation (38 vs 56) In an analysis of
Medicare claims data of patients undergoing lower-
extremity revascularization statin use was associ-
ated with lower rates of amputation at 30 days
90 days and 1 year (75) Single-center observational
data among patients with CLI suggest that statin
therapy is also associated with improved 1-year rates
of primary patency secondary patency and improved
limb salvage after endovascular intervention (73)
Patients with PAD should be prescribed a high-
intensity statin to reduce the risk of cardiovascular
events In most studies the rates of statin prescrip-
tion were lt75 which emphasizes the importance of
maximizing medical therapy among this high-risk
group of patients with advanced atheroscleroticdisease (59)
ANTIPLATELET THERAPY
ASPIRIN Aspirin has been a mainstay of drug ther-
apy among patients with PAD however the data
supporting aspirin use in patients with PAD have not
been well subst antia ted (7677)
Recent studies investigating the bene1047297t of aspirin
among patients with asymptomatic PAD have yielded
negative results Both the POPADAD (Prevention of
Progression of Arterial Disease and Diabetes) trial and
the AAA (Aspirin for Asymptomatic Atherosclerosis)
trial compared low-dose aspirin with placebo in
patients with a low ABI Neither study demonstrated
a reduction in fatal and nonfatal cardiovascular
events or revascularization with aspirin mono-
therapy although both notably included low-risk
patients with borderline ABI (099 in POPADAD
and 095 in AAA) (7778)
Consistent with these results a meta-analysis
speci1047297cally examined aspirin for PAD in 18 trials
involving 5269 patients In patients taking aspirin
monotherapy there was a nonsigni1047297cant reduction
in cardiovascular events (absolute event rate 82
vs 96 relative risk 075 95 con1047297dence inter-
val [CI] 048 to 118) however there was a sig-
ni1047297cant reduction in nonfatal stroke (HR 064 95
CI 042 to 099 p frac14 004) (76) In the last iteration
of the PAD guidelines (2) aspirin was a Class I
Level of Evidence A recommendation among pa-
tients with symptomatic PAD a Class IIa recom-
mendation among patients with asymptomatic PAD
and an ABI lt090 and a Class IIb indication among
asymptomatic patients with an ABI of 090 to 099
(2) Some of these recommendations may change in
the upcoming revision of the ACCAHA PAD prac-
tice guidelines
CLOPIDOGREL AND
DUAL-ANTIPLATELET THERAPY
Clopidogrel is indicated as an alternative to aspirin
for antiplatelet monotherapy among patients with
PAD although recent studies suggest that lt20 of
patients with PAD are prescribed clopidogrel in clin-
ical practice (79) The data supporting clopidogrel use
are primarily based on the CAPRIE (Clopidogrel
Versus Aspirin in Patients at Risk of Ischaemic
Events) study in which clopidogrel monotherapy was
associated with a small bene1047297t compared with aspirin
325 mg daily in the overall population but there was a
238 relative risk reduction among the subgroup of
patients with symptomatic PAD (n frac14 6452 absolute
event rate 37 vs 49 per year) (80)
Dual-antiplatelet therapy (DAPT) with low-dose
aspirin (75 to 162 mg daily) and clopidogrel 75 mg
daily was studied in the CHARISMA (Clopidogrel for
High Atherothrombotic Risk and Ischemic Stabiliza-
tion Management and Avoidance) trial which
included patients at high risk for atherothrombotic
events The overall results of this trial were not sig-
ni1047297cant although in subgroup analyses there was a
bene1047297t of DAPT among patients with symptomatic
atherothrombosis (81) In an analysis of the 3096 pa-
tients in the trial with PAD DAPT was associated with
a lower rate of myocardial infarction (23 vs 37

composite primary endpoint (82) There was no dif-
ference between the groups in moderate severe or
fatal bleeding but there was an increase in minor
bleed ing i n th e DAPT group
In a recent propensity-matched observational
study among patients undergoing endovascular
intervention there was a signi1047297cant reduction in
MACE among patients taking DAPT (adjusted HR
065 95 CI 044 to 096 p frac14 003) compared with
those taking aspirin monotherapy (83) The discor-
dant 1047297ndings between this study and the CHARISMA
trial may be explained by inclusion of a cohort
with more advanced atherosclerotic disease under-
going endovascular intervention including gt50 of
patients with CLI
The CASPAR (Clopidogrel and Acetylsalicylic Acid
in Bypass Surgery for Peripheral Arterial Disease) trial
studied DAPT versus aspirin 75 to 100 mg daily among
patients undergoing below-knee surgical bypass for
treatment of CLI (84) The primary endpoint of death
major amputation index-graft occlusion or revascu-
larization was not different for DAPT versus
acetylsalicylic acid (ASA) monotherapy In a pre-
speci1047297ed subgroup analysis there was a signi1047297cant
bene1047297t of DAPT in patients treated with prosthetic
grafts (HR 065 95 CI 045 to 095 p frac14 0025) but
not in those treated with vein grafts A similar trial
the CAMPER study (Clopidogrel and Aspirin in the
Management of peripheral Endovascular Revascular-
ization) tested DAPT versus aspirin in patients un-
dergoing infrainguinal endovascular therapy The
study was never completed because of poor enroll-
ment (doctors would not randomize patients to ASA
alone) continued funding could not be justi1047297ed
DAPT is often prescribed after endovascular inter-
vention although the data supporting duration of
DAPTare sparseIn practice most physicians prescribe
DAPTfor a time periodrangingfrom1 to3 monthspost-intervention The ASPIRE-PAD study (Antiplatelet
Strategy for Peripheral Arterial Interventions for
Revascularization of Lower Extremities) is currently
evaluating comparative outcomes of 1 versus 12
months of DAPT after endovascular intervention (85)
VORAPAXAR
Thrombin acts through platelets via a unique mecha-
nism binding of the protease activating receptor-1
(PAR-1) a G protein-coupled receptor expressed on
the platelet surface leads to receptor activation
and increased intracellular Ca2thorn cyclic adenosine
monophosphate (cAMP) levels subsequently decrease
which leads to increased platelet aggregation and
releaseof further activatingfactors Vorapaxar inhibits
PAR-1 thereby signi1047297cantly reducing thrombin-
mediated platelet activation
T he T RA 2P-TIMI 50 trial (Thrombin Receptor
Antagonist for Secondary PreventionndashThrombolysis
in Myocardial Infarction Study Group) studied vor-
apaxar sulfate 25 mg daily versus placebo (ASA and
or clopidogrel therapy at the investigatorsrsquo discre-
tion) among 26449 patients with a recent myocardial
infarction recent ischemic stroke or symptomatic
PAD At 3 years there was a signi1047297cant reduction in
the primary endpoint of MACE (absolute event rates
93 vs 105 HR 087 95 CI 080 to 094
p lt 0001) (79) After 2 years the data and safety
monitoring board recommended stopping the study
drug in the patient subgroup entered with prior
ischemic stroke because of an increased risk of
intracranial hemorrhage Among the 3787 patients
with PAD the majority were treated with aspirin
monotherapy plus vorapaxar or placebo The reduc-
tion in MACE was not statistically signi1047297cant in those
assigned to vorapaxar (absolute event rates 113 vs
119 HR 094 95 CI 078 to 114) Similarly
negative results were observed among patients with
PAD who were enrolled in the TRACER (Thrombin
Receptor Antagonist for Clinical Event Reduction in
Acute Coronary Syndrome) trial (86) Additionally
vorapaxar is associated with a signi1047297cantly increased
risk of major bleeding However in both of these
trials there were relatively few MACE in the PAD
subgroup The PAD group was underpowered to draw
any conclusions on ef 1047297cacy
Pre-speci1047297ed analysis of limb-related outcomes in
the TRA 2P-TIMI 50 trial demonstrated that patients
assigned to vorapaxar had signi1047297cantly reduced rates
of acute limb ischemia (23 vs 39 HR 058 95
CI 039 to 086 p frac14 0006) as well as peripheral
artery revascularization (184 vs 222 HR 084
95 CI 073 to 097 p frac14 0017) during the 3-yearfollow-up (Figure 2) (87) These ef 1047297cacy endpoints
must be balanced by a signi1047297cantly increased rate of
major bleeding among patients prescribed vorapaxar
Further research into the mechanism by which
vorapaxar led to improved limb outcomes is required
to fully understand these effects
CELL-BASED AND ANGIOGENIC THERAPIES
Modulation and enhancement of lower-extremity
blood 1047298ow via angiogenesis arteriogenesis or vas-
culogenesis could provide a promising breakthrough
therapy for patients with PAD (88) Additionally

there has been much interest in the use of stem cellndash
derived endothelial cells or modi1047297cation of resident
stem cells (89) Potential bene1047297ts of these therapies
include improved wound healing and limb salvage
among patients with CLI as well as improved clau-
dication distance To date numerous cell-based and
angiogenic therapies have been tested and despite
promising results in early clinical trials none of these
agents have shown bene1047297t in larger trials
ONGOING CLINICAL TRIALS
There are currently 2 clinical trials studying novel
antiplatelet and anticoagulant agents to reduce MACE
and potentially modify limb-related outcomes
EUCLID (Study Comparing Cardiovascular Effects of
Ticagrelor and Clopidogrel in Patients With Periph-eral Artery Disease) is a randomized blinded double-
dummy trial comparing ticagrelor 90 mg twice daily
to clopidogrel monotherapy among 13500 patients
with PAD (90) All patients are tested for clopidogrel
resistance before randomization The primary
endpoint is a composite of MACE and results are
expected in late 2016 The COMPASS (Rivaroxaban for
the Prevention of Major Cardiovascular Events in
Coronary or Peripheral Artery Disease) trial is evalu-
ating low-dose rivaroxaban alone versus placebo
aspirin alone or rivaroxaban and aspirin among
21400 patients with a history of myocardial infarc-tion or PAD the primary endpoint of this trial is a
composite of MACE (91)
ENDOVASCULAR THERAPY
Endovascular revascularization plays a key role in the
management of patients with PAD Patients with sta-
ble cl audication have a low ris k of lim b loss but may be
severely limited by their symptoms In most circum-
stances patients with claudication should be offered a
trial of cilostazol and an exercise program as initial
therapy If the patient is not satis1047297ed after a trial of
medical therapy endovascular revascularization can be consi dere d Patie nts with CLI require more urgent
revascularization because of an increased riskof tissue
loss and amputation as well as an extremely high risk
of cardiovascular events (92)
There are 2 well-established classi1047297cation schemes
to describe the severity of PAD The 1047297rst is a func-
tional assessment (Fontaine or Rutherford classi1047297ca-
tion [RC]) (Table 2) and the second is an anatomic
lesion classi1047297cation (Trans-Atlantic Inter-Society
Consensus [TASC]) (Table 3) (45) In addition there
has been recent interest in the angiosome concept in
helping to in1047298uence optimal revascularization stra-tegies for limb salvage (93) An angiosome is an
anatomic unit of tissue (consisting of skin subcu-
taneous tissue fascia muscle and bone) that is fed
by a source arte ry and drai ned by speci1047297c veins
If the patient is a candidate for either endovascular
or open surgery the less invasive option (ie an
endovascular-1047297rst strategy) is the current standard of
care The selection of a complex lesion (TASC D) for
endovascular therapy will vary with the skill and
experience of the interventionalist The goal in
treating a patient who has functional impairment
because of claudi cation is dura ble relief of symptoms
In patients with CLI and a threatened limb or tissueloss the goal is rapid reperfusion of the ischemic

AORTOILIAC OCCLUSIVE DISEASE
There has been a practice shift over the past 25 years
as the treatment of aortoiliac disease transitioned
from open surgery with aortobiiliac or aortobifemoral
bypass to endovascular trea tment s for comple x and
diffuse disease (TASC D) This preference for less
invasive therapy is evidence based and driven by
shorter length of stay (or treatment as an outpatient
entirely) and lower periprocedural morbidity and
mortality rates while achieving comparable patency
rates (4- to 5-year primary patency of 60 to 86
with secondary patency rates of 80 to 98) (94)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) In 2011 the European Society of Car-
diology (ESC) (3) and ACCAHA PAD guidelines (2)
recommended an endovascular-1047297rst approach for
aortoiliac lesions recommended that borderline
lesions be assessed with hemodynamic gradients and
supported primary stent placement in the aortoiliac
arteries (Table 4) The current expert consensus
document from the Society for Cardiac Angiography
and Interventions (SCAI) on appropriate use criteria
(AUC) for aortoiliac intervention are similar to the
current guidelines (95)

Treatment of TASC A B C and D Iliac Lesions) re-
ported 100 technical success in 325 patients with
aortoiliac lesions with a 24-month primary patency
rate of 879 (96) Neither TASC category nor lesion
length was predictive of restenosis These data
further support the endovascular-1047297rst strategy
regardless of TASC classi1047297cation and take into
consideration the evolution of devices (ie re-entry
catheters crossing devices and stents) which
improve success rates for the most complex lesions
COMMON FEMORAL DISEASE
Patients with common femoral artery (CFA) disease
are particularly symptomatic because the obstruction
not only occurs proximal to the super1047297cial femoral
artery (SFA) but also proximal to the deep femoralartery (profunda femoris) which is the major collat-
eral artery supplying blood to the lower limb when
there is SFA obstruction Traditionally common
femoral endarterectomy has been the CFA revascu-
larization procedure of choice (23) although
advances in endovascular therapy have shown some
promising results (97) A review of the National Sur-
gical Quality Improvement Program database for 2005
to 2010 found a combined mortality and morbidity
rate of 15 for common femoral endarterectomy
which was higher than expected (98) Patients
requiring CFA revascularization who are at increasedsurgical risk may be considered for less invasive
endovascular options
FEMORAL-POPLITEAL DISEASE
This segment begins at the bifurcation of the CFA into
the SFA and the deep femoral (profunda femoris)
artery The SFA is subject to 1047298exion elongation
compression and torsion unlike any other lower-
extremity artery This complexity leads to many
challenges for endovascular technology but despite
this an endovascular-1047297rst approach is currently thestandard of therapy for the majority of lesions
becau se of the very high proce dural success rate and
low risk (3) Some of the most lengthy and complex
lesions (TASC D) are more approachable because of
the re-entry and crossing devices more experienced
operators drug-eluting stents (DES) (99100) and
drug-coated balloons (DCBs) (101ndash107) that promise
improved long-term patency for patients with clau-
dication (99100103105)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines and the AUC documentfrom the SCAI recommend revascularization in
femoral-popliteal lesions for patients with CLI or for
patients with claudication who have had a suboptimal
r espon se to a tr ial of e xer cise (Tab le 5) An
endovascular-1047297rst approach is recommended for
TASC A through C lesions and is a reasonable option
for TASC D lesions depending on the experience of
the operator the patientrsquos comorbidities and proce-
dure safety (Table 5) (2395)
The 2 guidelines are in con1047298ict over the use of
primary stent placement in the femoral-popliteal ar-
teries with the ACCAHA guideline giving it a Class III
recommendation (do not do) and the ESC guideline
making primary femoral stenting reasonable 1047297rst-line
therapy (Class IIa) for intermediate-length lesions
(108109) The current evidence from several ran-
domized controlled trials supports primary stenting
in intermediate-length femoral stenoses and occlu-
sions (108ndash110) The soon-to-be-published updatedACCAHA guidelines will readdress this issue In
current practice the standard is to primarily stent
intermediate to long SFA lesions
The ACCAHA guideline broadly lump stents
togetherwith atherectomy devicescryotherapy laser
and cutting balloons stating they may be useful as
salvage therapy (Class IIa) but also stating that their
effectiveness remains to proven (Class IIb) Stents
should be removed from this group because their
effectiveness has been established in intermediate-
length femoral lesions Other than the use of the cut-
ting balloon and rotational atherectomy in lesions thatare resistant to dilation there is no comparative

evidence suggesting that the more expensive athe-
rectomy devices cryoplasty or laser angioplasty
should be preferred over conventional therapy
(percutaneous transluminal angioplasty [PTA] and
bare- metal stents [BMS] ) The ESC guideline disti n-
guishes bare-metal self-expanding stents from
adjunctive devices such as atherectomy devices cit-
i ng the p roven bene1047297t of BMS over PTA in
intermediate-length femoral-popliteal lesions
CLINICAL TRIAL UPDATE Three randomized controlledtrials of self-expanding BMS compared with PTA have
shown that the advantage for primary stenting is
related to lesion length For relatively discrete lesions
(mean 45 mm) (110) there was no advantage for pri-
mary stent placement however 2 other trials
(108109) with longer lesions (gt70 mm) showed a
signi1047297cant patency and functional bene1047297t for primary
femoral-popliteal BMS (Figure 3 Table 6) The proce-
dural success rate of endovascular therapy in
femoral-popliteal lesions is very high but in stable
limb ischemia durable patency remains a barrier
Cilostazol has been shown to reduce 1-year restenosis by more than one-half (20 vs 49 p frac14 00001) in
intermediate-length (128 mm) femoral lesions treated
with self-expanding BMS (114) These results need to
be con1047297rmed before this can be recommended as
standard therapy
Recent randomized controlled trials demonstrating
bene1047297t f or DE S (99100) DC B (103105106) and
covered stents (115ndash117) in femoral-popliteal arteries
will likely result in a change in the guidelines and
indications (Table 6 Figure 3)
There hasbeen some enthusiasm for self-expanding
covered (expanded polytetra1047298uoroethylene) stent
grafts in complex or lengthy femoral-popliteal seg-
ments Two randomized trials comparing covered
stents to BMS had divergent results One showed a
bene1047297t for 2-year primary patency but no difference in
target-lesion revascularization (TLR) or clinical out-
comes (116) whereas the other in longer (gt8 cm) le-
sions found no difference for primary patency (115ndash
117) When covered stents were compared with
above-the-knee femoral bypass with synthetic graft
material in a broad range of SFA lesion types (TASC A
thru D) no difference was found in the 4-year primary
patency between the 2 options (118)
The Zilver paclitaxel-eluting self-expanding DES
was superior to PTA in a randomized femoral-
popliteal trial with 1-year patency rates of 831 for
primary DES and 328 for PTA (p lt 0001) (Figure 3
Table 6) (99) There was also a 1-year patency
advantage for provisional DES after failed PTA
(899) compared with provisional BMS (730
p frac14 001) The bene1047297t was sustained at 2 years with
primary patency for the DES (748) signi1047297cantly
better t han PTA (265 p lt 001) (100) To date there
has been no head-to-head comparison of primary DES
to either BMS or DCB in femoral-popliteal arteries
but Zelle r et al (104) published a propensity scorendash
based compar ison of DES and DCB in conse cutive
patients with TASC C and D long (gt10 cm) lesions and
found no signi1047297cant differences in 1-year patency
(Figure 3 Table 6)
DCBs offer the promise of improved patency with areduced need for stents This is particularly important
in the dynamic environment of the super1047297cial femoral
and popliteal arteries where mechanical fatigue may
lead to stent fracture and increased risk of in-stent
restenosis Each DCB is unique with respect to the
paclitaxel dose (varying from 2 to 35 mgmm2) the
carrier molecule (excipient) the balloon material and
the coating technology used Superiority for paclitaxel
DCB over PTA was 1047297rst reported in 2008 (101102)
(Figure 3 Table 6) Subsequently new DCBs have
emerged including the INPACT (105106111113) and
the Lutonix (103106) balloons both of which showedclinical superiority to PTA in femoral-popliteal lesions

Endovascular procedures are indicated for patientswith a vocational or lifestyle-limiting disabilitydue to intermittent claudication when clinicalfeatures suggest a reasonable likelihood of symptomatic improvement with endovascularintervention and 1) there has been aninadequate response to exercise orpharmacological therapy andor 2) there is avery favorable risk-bene1047297t ratio (eg focalstenosis) (Class I Level of Evidence A)
When revascularization is indicated anendovascular-1047297rst strategy isrecommended in all femoropoplitealTASC AndashC lesions (Class I Level of
Evidence C)
Stents (and other adjunctive techniques such aslasers cutting balloons atherectomy devicesand thermal devices) can be useful in thefemoral popliteal and tibial arteries as salvagetherapy for a suboptimal or failed result fromballoon dilation (eg persistent translesionalgradient residual diameter stenosis gt50 or1047298ow-limiting dissection) (Class IIa Level of
Evidence C)
Primary stent implantation should beconsidered in femoropopliteal TASCB lesions (Class IIa Level of
Evidence A)
The effectiveness of stents atherectomy cuttingballoons thermal devices and lasers for thetreatment of femoral-popliteal arterial lesions isnot well established (except to salvage asuboptimal result from balloon dilation) (Class
IIb Level of Evidence A)
A primary endovascular approach mayalso be considered in TASC D lesionsin patients with severe comorbiditiesif an experienced interventionist isavailable (Class IIb Level of
Evidence C)
Primary stent placement is not recommended in thefemoral popliteal or tibial arteries (Class III
Level of Evidence C)
Endovascular intervention is not indicated asprophylactic therapy in an asymptomatic patientwith lower-extremity PAD (Class III Level of
Evidence C)

TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous

CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

claudication therapy In contrast changes in limb
hemodynamics such as an improvement in the ABI or
imaging after a successful revascularization serve
only as surrogate measures of clinical bene1047297t
Exercise training has been a mainstay of treatment
for symptomatic PAD with a well-established bene1047297t
after a typical 12-week exercise training program
(3334) Exercise training directly modi1047297es several
pathophysiological mechanisms in PAD including
improved skeletal muscle metabolism endothelial
function and gait biomechanics (35)
SUPERVISED EXERCISE TRAINING I MPROVES MORBIDITY
AND MORTALITY IN PAD Individual single-site studies
and a meta-analysis of those studies demonstrate that
a 12-week intervention of supervised exercise (SE)
improves exercise performance and QOL in PAD (34)Supervised exercise is also more effective than a
nonstructured community exercise program (36)
Physical activity in patients with PAD is associated
with decreased all-cause and cardiovascular mortality
(3738) Standardized supervised training methods
have been published previously (39)
On the basis of current evidence supervised
walking exercise gets a Class Ia recommendation and
unsupervised exercise a Class IIb recommendation
(2) Despite clear evidence of bene1047297t SE programs
have not been accepted by payers providers or
patients for a variety of reasons including questionsof long-term adherence and the bene1047297t of exercise as a
lifestyle intervention coupled with the desire by most
patients and vascular physicians for a more immedi-
ate approach to relieving claudication with endovas-
cular therapy (40) Therefore SE training programs
for claudication are very limited and not reimbursed
HOME-BASED EXERCISE DATA AND GENERALIZABILITY
OF THE FINDINGS The methodology to provide a
community (home)-based exercise intervention has
improved considerably over the past decade and
these exercise training methods have provided
encouraging resultsThe least resource-intensive home-based program
can employ education and behavioral interventions
that prepare patients for exercise training (41)
Notably adherence to a community program may be
poor without proper motivation and engagement
There are a number of new devices that monitor
the intensity and duration of an exercise session
performed in the home environment A pilot study
that used a program of training monitoring and
coaching had encouraging results in a subgroup of
subjects but was too small to de1047297nitively establish the
bene1047297ts of the interventions (42) Two larger trialsused a step activity monitor to record the duration
and intensity of the walking exercise to inform the
research staff and patient as to the patientrsquos exercise
prescription One randomized trial combined the
activity monitor with a home-based program that
used the principles of a hospital-based supervised
program (43) Adherence to the home program was
gt80 and the results on improvements in treadmill
exercise performance were comparable between
home and supervised programs A follow-up study
demonstrated similar results (44)
McDermott et al (45) have developed a coordinated
exercise program (group-mediated cognitive behav-
ioral therapy) that includes weekly group sessions run
by a trained facil itato r In a rando mized controlled
trial of 194 patients subjects in the intervention group
improved their 6-min walkingdistance peak treadmill
exercise performance and several measures of QOL
and accelerometer-measured physical activity (46)
In addition after 6 months the intervention group
gained self-ef 1047297cacy satisfaction with functioning
pain acceptance and social functioning and these
bene1047297ts weresustained at the 12-monthendpoint (47)
At 12 months fewer treated patients experienced
mobility loss and treated patients also improved in
walking velocity and QOL (48)
It is apparent that many of the exercise methods
discussed are effective in improving walking distance
with less discomfort and improved QOL however
they all require resources that are not available in
many communities especially those in the lowest
socioeconomic class Although a simple recommen-
dation between the physician and the patient to exer-
cise is usually ineffective the physician can provide
a comprehensive exercise prescription (Table 1) on
how to structure a home exercise program (5051)
This is not a 1-time recommendation but an ongoing
discussion between the physician and the patient
in an attempt to change patient behavior Patients
who are compliant with such a program often experi-
ence considerable improvement in walking distance

THERAPY ARE WE ASKING THE RIGHT QUESTIONS
Several studies have compared an SE program to
revascula ri za ti on i n p atients wi th PAD a nd
exercise-limiting claudication (5253) G iven t he
tremendous expansion and effectiveness of endovas-
cular treatments for symptomatic PAD as well as
patient reluctance to enter an exercise-lifestyle treat-
ment program (as discussed previously) the most
prudent approach would be to include both modalities
in the treatment plan exercise and revascularization
In fact both exercise training and revascularizationcan greatly improve patient exercise performance

and QOL but by very different mechanisms Revascu-
larization primarily improves exercise blood 1047298ow
whereas exercise training does not (29) In contrast
exercise training induces a variety of adaptive re-
sponses including improved skeletal muscle mito-
chondrial oxidative metabolismimproved endothelialfunction and more ef 1047297cient biomechanics of walking
Thus the obvious ldquo bestrdquo treatment strategy would
appear to be the combined program utilizing endo-
vascular revascularization and an optimal home-based
and long-term exercise program This hypothesis
was initially tested more than 25 years ago and the
combination of bypass surgery and exercise training
was superior to either treatment alone (54)
The CLEVER (Claudication Exercise Versus Endo-
luminal Revascularization) study was an important
and well-designed comparative effectiveness trial
that compared the outcomes for stenting of aortoiliacdisease with SE on a background of optimal medical
therapy in both groups (52) At the initial 6-month
follow up the primary endpoint of peak walking
time on a graded treadmill test was signi1047297cantly
improved in both the exercise and stent groups
compared with optimal medical management but the
peak walking time was signi1047297cantly higher in the
exercise group than in the stent group (52) The sec-
ondary endpoints were changes in responses to QOL
questionnaires Both of these patient-reported out-
comes were improved with exercise or stenting over
optimal medical management however improve-
ments tended to be greater in the stenting group The
same endpoints were measured at 18 months of
follow-up (55) In 79 of 119 patients who completed
the study improvements in treadmill peak walking
time remained for both the exercise and stenting
groups over optimal medical therapy but the differ-
ences in peak walking time between the exercise and
stenting groups were no longer statistically signi1047297-
cant Improved patient-reported outcomes remained
for both the exercise and stent groups
CLEVER clearly established the independent long-
term and broad-based bene1047297ts of both exercise
training and stent revascularization in symptomatic
PAD Similar to many such trials of the nearly 1000
patients evaluated only 11 were randomized and
fewer were available for 18-month follow-up Unfor-
tunately the arm of CLEVER that would have tested
the combination of exercise plus stenting was drop-
ped because of poor enrollment
In the recently published ERASE (Endovascular
Revascularization and Supervised Exercise) trial
106 patients were randomized to both endovascular
therapy and SE and 106 patients to SE alone (56) After
1 year the combination group had greater improve-
ment in maximum walking distance (MWD) and
health-related QOL scores than the group randomized
to SE alone however both groups demonstrated
dramatic improvement in MWD pain-free walking
distance and QOL The supervised exercise group
increased MWD from 285 m to 1240 m for animprovement of 955 m The combination group
increased MWD from 264 m to 1501 m for an
improvement of 1237 m This study illustrates
2 important points 1) the combinationof endovascular
therapy and SE is the most effective therapy for many
patients with claudication and 2) even the group
randomized to SE alone showed marked improvement
in MWD pain-free walking distance and QOL (56)
The cost of therapy must also be considered when
planning a particular strategy to treat symptomatic
PAD In a single-center Dutch randomized trial
endovascular revascularization had similar bene1047297t but highe r total mean cumula tive costs per patie nt
T A B L E 1 A Practical Home Exercise Program for Patients
With PAD
Frequency
3-5 days per week
Modality
Treadmill (this program can be adapted for walking outside)
Method
1 Begin at 2 mph and a grade of 0 (1047298at)
2 Try not to hold onto the treadmill Use the side panels for balanceonly
3 Stop the treadmill completely when pain is 3ndash4 on claudicationdiscomfort scale
4 When the discomfort has ceased resume exercise at the sameintensity
5 Repeat restexercise cycles
6 Progress to a higher workload when you can walk for 8 minwithout having to stop for leg symptoms
a) Increase speed by 02 mph each time you can walk for 8 min
b) Once you are able to walk at 34 mph or reach a speed at whichyou can no longer keep up begin increasing the grade by 1
Duration
The total exercise period including rest periods should equal45 min per day
Tips for success
1 Do not continue walking past 3ndash4 on claudication paindiscomfortscale This way the paindiscomfort should go away in 2ndash5 min If you walk until you are in severe pain you will build up lactic acidin your muscles and it will take much longer for the pain to goaway
2 When at 3ndash4 on paindiscomfort scale stop walking completelyDo not slow down but stop and stand on the treadmill until thediscomfort is gone
This works if you do it Not only will this improve your walkingperformance decrease your discomfort and improve your
quality of life this type of program is also bene1047297cial for yourheart blood pressure and lipid (cholesterol and triglyceride)levels

compared with a hospital-based exercise program
(57) Another study from a Dutch health-care databaseof 4954 patients demonstrated that a stepped
approach of exercise therapy followed by endovas-
cular revascularization was more cost-effective than
revascularization only (58)
Thus future studies should address not only the
clinical bene1047297ts but also the effectiveness of the
combination of an exercise program and limb revas-
cularization In this context effectiveness pertains to
the ability of a treatment program to be utilized by a
majority of appropriate patients in a community and
to achieve high adherence to the program as well as
that the desired improvements in functional out-comes are obtained
OPTIMAL MEDICAL THERAPY FOR
PATIENTS WITH PAD
Medical therapy for PAD should address treatment for
limb-related outcomes (improve claudication symp-
toms and prevent CLI and amputation) and treatment
to prevent major adverse cardiovascular events
(MACE myocardial infarction stroke and cardio-
vascular death) (Central Illustration)
Despite the recommendations from societal
guidelines on the management of patients with PAD(2) these patients continue to be undertreated
compared with patients with CAD (859) Adherence
to these guidelines in real-world practice is associatedwith improved outcomes (Figure 1) which empha-
sizes the bene1047297t of multifactorial risk reduction in
this high-risk population (12) Performance measures
for PAD will help improve quality of care and may be
incorporated into future quality metrics (60)
SMOKING CESSATION
Smoking is a major risk factor for the developmentand
progression of PAD A multidisciplinary approach to
smoking cessation should be used including group-
based programs and cognit ive beha viora l therapy
A recent study evaluated the association betweensuccessful quitting after endovascular intervention
and long-term outcomes (61) Among 739 patients
undergoing lower-extremity angiography 28 were
active smokers at the time of endovascular interven-
tion In the subsequent year 30 of active smokers
successfully quit Those who remained off tobacco
had signi1047297cantly lower 5-year mortality (14 vs 31)
and improved amputation-free survival (81 vs
60) Discontinuation of smoking is the most
important lifestyle modi1047297cation in preventing CLI
amputation and MACE in patients with PAD This
needs to be conveyed to the patient in an empatheticand nonjudgmental way during every of 1047297ce visit The

PHARMACOTHERAPY TO IMPROVE
CLAUDICATION SYMPTOMS
Cilostazol is a type III phosphodiesterase inhibitorwith a number of properties but the mechanism by
which cilostazol improves claudication is not known
(63) A pooled analysis of all of the randomized
trials shows an improvement in absolute claudica-
tion distance of approximately 50 compared with
placebo (64) Although cilostazol appears to be safe
for long-term administration adherence is low (gt60
discontinuation at 3 years) because of adverse effects
including headache palpitations and diarrhea (65)
Because of its mechanistic similarity to other type III
phosphodiesterase inhibitors such as milrinone cil-
ostazol is contraindicated in patients with a history of
heart failure The optimal dose of cilostazol is 100 mg
twice daily and it may take up to 4 months to derive
maximum bene1047297t from this drug (63)
Pentoxifylline is rarely used today to treat claudi-
cation because of a lack of ef 1047297cacy compared with
cilostazol Naftidrofuryl is a 5-HT2 antagonist that is
approved in Europe In a pooled analysis involving
888 patients randomized to naftidrofuryl there was a
26 increase in pain-free walking compared with
placebo (66) It is not available for use in the United
States
ACEIs
ACEIs are associated with a signi1047297cant reduction in
MACE among patients with PAD These data are
derived primarily from the HOPE (Heart Outcomes
Prevention Evaluation) trial which randomized 9297
high-risk patients with vascular disease or diabetes
plus 1 other risk factor to ramipril 10 mg daily
or placebo Among these 1966 patients with PAD
(423) were randomized to ramipril and 2085
(448) to placebo The primary outcome (myocardial
infarction stroke cardiovascular death) occurred in
143 of those without PAD versus 220 of those
with PAD (67) In the 5231 patients without PAD the
primary outcome was observed in 126 in the ram-
ipril group and 149 in the placebo arm In those with
an ABI lt06the primary outcome occurred in 164 in
the ramipril arm versus 22 in the placebo arm Thecardiovascular bene1047297t of ramipril applies to patients
with both asymptomatic and symptomatic PAD across
a broad range of ABI values (68) Similar results have
also been observed with telmisartan which suggests a
possible class effect of ACEIangiotensin receptor
blockade among patients with PAD (6970)
STATINS
High-intensity statin medications are recommended
for a ll pa ti ents with PAD on the basis of the

emphasize cardiovascular risk over low-density lipo-
protein targets (71) The majority of the data in sup-
port of statin use in patients with PAD are derived
from subset analysis of larger clinical trials The
Medical Research CouncilBritish Heart Foundationrsquos
Heart Protection Study randomized 20536 high-risk
patients to simvastatin 40 mg daily or placebo (72)
All-cause mortality occurred in 129 of patients
randomized to simvastatin and 147 randomized to
placebo (22 relative risk reduction p frac14 00003)
Observational studies have also con1047297rmed the car-
diovascular and overall mortality bene1047297t of statins
among patients with more advanced PAD including
CLI (73)
Recent data suggest that statin use is also associ-
ated with a reduction in adverse limb outcomes
including amputation In the REACH (Reduction of
Atherothrombosis for Continued Health) registry
statin therapy was associated with a signi1047297cant
reduction in the combined endpoint of worsening
claudication new CLI new revascularization or
amputation (74) The absolute 4-year event rates were
220 versus 262 which emphasizes the highrate of
adverse limb events among patients with symptom-
atic PAD Importantly statin therapy was also associ-
ated with a signi1047297cant reduction in 4-year rates of
ischemic amputation (38 vs 56) In an analysis of
Medicare claims data of patients undergoing lower-
extremity revascularization statin use was associ-
ated with lower rates of amputation at 30 days
90 days and 1 year (75) Single-center observational
data among patients with CLI suggest that statin
therapy is also associated with improved 1-year rates
of primary patency secondary patency and improved
limb salvage after endovascular intervention (73)
Patients with PAD should be prescribed a high-
intensity statin to reduce the risk of cardiovascular
events In most studies the rates of statin prescrip-
tion were lt75 which emphasizes the importance of
maximizing medical therapy among this high-risk
group of patients with advanced atheroscleroticdisease (59)
ANTIPLATELET THERAPY
ASPIRIN Aspirin has been a mainstay of drug ther-
apy among patients with PAD however the data
supporting aspirin use in patients with PAD have not
been well subst antia ted (7677)
Recent studies investigating the bene1047297t of aspirin
among patients with asymptomatic PAD have yielded
negative results Both the POPADAD (Prevention of
Progression of Arterial Disease and Diabetes) trial and
the AAA (Aspirin for Asymptomatic Atherosclerosis)
trial compared low-dose aspirin with placebo in
patients with a low ABI Neither study demonstrated
a reduction in fatal and nonfatal cardiovascular
events or revascularization with aspirin mono-
therapy although both notably included low-risk
patients with borderline ABI (099 in POPADAD
and 095 in AAA) (7778)
Consistent with these results a meta-analysis
speci1047297cally examined aspirin for PAD in 18 trials
involving 5269 patients In patients taking aspirin
monotherapy there was a nonsigni1047297cant reduction
in cardiovascular events (absolute event rate 82
vs 96 relative risk 075 95 con1047297dence inter-
val [CI] 048 to 118) however there was a sig-
ni1047297cant reduction in nonfatal stroke (HR 064 95
CI 042 to 099 p frac14 004) (76) In the last iteration
of the PAD guidelines (2) aspirin was a Class I
Level of Evidence A recommendation among pa-
tients with symptomatic PAD a Class IIa recom-
mendation among patients with asymptomatic PAD
and an ABI lt090 and a Class IIb indication among
asymptomatic patients with an ABI of 090 to 099
(2) Some of these recommendations may change in
the upcoming revision of the ACCAHA PAD prac-
tice guidelines
CLOPIDOGREL AND
DUAL-ANTIPLATELET THERAPY
Clopidogrel is indicated as an alternative to aspirin
for antiplatelet monotherapy among patients with
PAD although recent studies suggest that lt20 of
patients with PAD are prescribed clopidogrel in clin-
ical practice (79) The data supporting clopidogrel use
are primarily based on the CAPRIE (Clopidogrel
Versus Aspirin in Patients at Risk of Ischaemic
Events) study in which clopidogrel monotherapy was
associated with a small bene1047297t compared with aspirin
325 mg daily in the overall population but there was a
238 relative risk reduction among the subgroup of
patients with symptomatic PAD (n frac14 6452 absolute
event rate 37 vs 49 per year) (80)
Dual-antiplatelet therapy (DAPT) with low-dose
aspirin (75 to 162 mg daily) and clopidogrel 75 mg
daily was studied in the CHARISMA (Clopidogrel for
High Atherothrombotic Risk and Ischemic Stabiliza-
tion Management and Avoidance) trial which
included patients at high risk for atherothrombotic
events The overall results of this trial were not sig-
ni1047297cant although in subgroup analyses there was a
bene1047297t of DAPT among patients with symptomatic
atherothrombosis (81) In an analysis of the 3096 pa-
tients in the trial with PAD DAPT was associated with
a lower rate of myocardial infarction (23 vs 37

study among patients undergoing endovascular

MACE among patients taking DAPT (adjusted HR

those taking aspirin monotherapy (83) The discor-
dant 1047297ndings between this study and the CHARISMA
trial may be explained by inclusion of a cohort
with more advanced atherosclerotic disease under-
going endovascular intervention including gt50 of
patients with CLI
The CASPAR (Clopidogrel and Acetylsalicylic Acid
in Bypass Surgery for Peripheral Arterial Disease) trial
studied DAPT versus aspirin 75 to 100 mg daily among
patients undergoing below-knee surgical bypass for
treatment of CLI (84) The primary endpoint of death
major amputation index-graft occlusion or revascu-
larization was not different for DAPT versus
acetylsalicylic acid (ASA) monotherapy In a pre-
speci1047297ed subgroup analysis there was a signi1047297cant
bene1047297t of DAPT in patients treated with prosthetic
grafts (HR 065 95 CI 045 to 095 p frac14 0025) but
not in those treated with vein grafts A similar trial
the CAMPER study (Clopidogrel and Aspirin in the
Management of peripheral Endovascular Revascular-
ization) tested DAPT versus aspirin in patients un-
dergoing infrainguinal endovascular therapy The
study was never completed because of poor enroll-
ment (doctors would not randomize patients to ASA
alone) continued funding could not be justi1047297ed
DAPT is often prescribed after endovascular inter-
vention although the data supporting duration of
DAPTare sparseIn practice most physicians prescribe
DAPTfor a time periodrangingfrom1 to3 monthspost-intervention The ASPIRE-PAD study (Antiplatelet
Strategy for Peripheral Arterial Interventions for
Revascularization of Lower Extremities) is currently
evaluating comparative outcomes of 1 versus 12
months of DAPT after endovascular intervention (85)
VORAPAXAR
Thrombin acts through platelets via a unique mecha-
nism binding of the protease activating receptor-1
(PAR-1) a G protein-coupled receptor expressed on
the platelet surface leads to receptor activation
and increased intracellular Ca2thorn cyclic adenosine
monophosphate (cAMP) levels subsequently decrease
which leads to increased platelet aggregation and
releaseof further activatingfactors Vorapaxar inhibits
PAR-1 thereby signi1047297cantly reducing thrombin-
mediated platelet activation
T he T RA 2P-TIMI 50 trial (Thrombin Receptor
Antagonist for Secondary PreventionndashThrombolysis
in Myocardial Infarction Study Group) studied vor-
apaxar sulfate 25 mg daily versus placebo (ASA and
or clopidogrel therapy at the investigatorsrsquo discre-
tion) among 26449 patients with a recent myocardial
infarction recent ischemic stroke or symptomatic
PAD At 3 years there was a signi1047297cant reduction in
the primary endpoint of MACE (absolute event rates
93 vs 105 HR 087 95 CI 080 to 094
p lt 0001) (79) After 2 years the data and safety
monitoring board recommended stopping the study
drug in the patient subgroup entered with prior
ischemic stroke because of an increased risk of
intracranial hemorrhage Among the 3787 patients
with PAD the majority were treated with aspirin
monotherapy plus vorapaxar or placebo The reduc-
tion in MACE was not statistically signi1047297cant in those
assigned to vorapaxar (absolute event rates 113 vs
119 HR 094 95 CI 078 to 114) Similarly
negative results were observed among patients with
PAD who were enrolled in the TRACER (Thrombin
Receptor Antagonist for Clinical Event Reduction in
Acute Coronary Syndrome) trial (86) Additionally
vorapaxar is associated with a signi1047297cantly increased
risk of major bleeding However in both of these
trials there were relatively few MACE in the PAD
subgroup The PAD group was underpowered to draw
any conclusions on ef 1047297cacy
Pre-speci1047297ed analysis of limb-related outcomes in
the TRA 2P-TIMI 50 trial demonstrated that patients
assigned to vorapaxar had signi1047297cantly reduced rates
of acute limb ischemia (23 vs 39 HR 058 95
CI 039 to 086 p frac14 0006) as well as peripheral
artery revascularization (184 vs 222 HR 084
95 CI 073 to 097 p frac14 0017) during the 3-yearfollow-up (Figure 2) (87) These ef 1047297cacy endpoints
must be balanced by a signi1047297cantly increased rate of
major bleeding among patients prescribed vorapaxar
Further research into the mechanism by which
vorapaxar led to improved limb outcomes is required
to fully understand these effects
CELL-BASED AND ANGIOGENIC THERAPIES
Modulation and enhancement of lower-extremity
blood 1047298ow via angiogenesis arteriogenesis or vas-
culogenesis could provide a promising breakthrough
therapy for patients with PAD (88) Additionally

there has been much interest in the use of stem cellndash
derived endothelial cells or modi1047297cation of resident
stem cells (89) Potential bene1047297ts of these therapies
include improved wound healing and limb salvage
among patients with CLI as well as improved clau-
dication distance To date numerous cell-based and
angiogenic therapies have been tested and despite
promising results in early clinical trials none of these
agents have shown bene1047297t in larger trials
ONGOING CLINICAL TRIALS
There are currently 2 clinical trials studying novel
antiplatelet and anticoagulant agents to reduce MACE
and potentially modify limb-related outcomes
EUCLID (Study Comparing Cardiovascular Effects of
Ticagrelor and Clopidogrel in Patients With Periph-eral Artery Disease) is a randomized blinded double-
dummy trial comparing ticagrelor 90 mg twice daily
to clopidogrel monotherapy among 13500 patients
with PAD (90) All patients are tested for clopidogrel
resistance before randomization The primary
endpoint is a composite of MACE and results are
expected in late 2016 The COMPASS (Rivaroxaban for
the Prevention of Major Cardiovascular Events in
Coronary or Peripheral Artery Disease) trial is evalu-
ating low-dose rivaroxaban alone versus placebo
aspirin alone or rivaroxaban and aspirin among
21400 patients with a history of myocardial infarc-tion or PAD the primary endpoint of this trial is a
composite of MACE (91)
ENDOVASCULAR THERAPY
Endovascular revascularization plays a key role in the
management of patients with PAD Patients with sta-
ble cl audication have a low ris k of lim b loss but may be
severely limited by their symptoms In most circum-
stances patients with claudication should be offered a
trial of cilostazol and an exercise program as initial
therapy If the patient is not satis1047297ed after a trial of
medical therapy endovascular revascularization can be consi dere d Patie nts with CLI require more urgent
revascularization because of an increased riskof tissue
loss and amputation as well as an extremely high risk
of cardiovascular events (92)
There are 2 well-established classi1047297cation schemes
to describe the severity of PAD The 1047297rst is a func-
tional assessment (Fontaine or Rutherford classi1047297ca-
tion [RC]) (Table 2) and the second is an anatomic
lesion classi1047297cation (Trans-Atlantic Inter-Society
Consensus [TASC]) (Table 3) (45) In addition there
has been recent interest in the angiosome concept in
helping to in1047298uence optimal revascularization stra-tegies for limb salvage (93) An angiosome is an
anatomic unit of tissue (consisting of skin subcu-
taneous tissue fascia muscle and bone) that is fed
by a source arte ry and drai ned by speci1047297c veins
If the patient is a candidate for either endovascular
or open surgery the less invasive option (ie an
endovascular-1047297rst strategy) is the current standard of
care The selection of a complex lesion (TASC D) for
endovascular therapy will vary with the skill and
experience of the interventionalist The goal in
treating a patient who has functional impairment
because of claudi cation is dura ble relief of symptoms
In patients with CLI and a threatened limb or tissueloss the goal is rapid reperfusion of the ischemic

AORTOILIAC OCCLUSIVE DISEASE
There has been a practice shift over the past 25 years
as the treatment of aortoiliac disease transitioned
from open surgery with aortobiiliac or aortobifemoral
bypass to endovascular trea tment s for comple x and
diffuse disease (TASC D) This preference for less
invasive therapy is evidence based and driven by
shorter length of stay (or treatment as an outpatient
entirely) and lower periprocedural morbidity and
mortality rates while achieving comparable patency
rates (4- to 5-year primary patency of 60 to 86
with secondary patency rates of 80 to 98) (94)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) In 2011 the European Society of Car-
diology (ESC) (3) and ACCAHA PAD guidelines (2)
recommended an endovascular-1047297rst approach for
aortoiliac lesions recommended that borderline
lesions be assessed with hemodynamic gradients and
supported primary stent placement in the aortoiliac
arteries (Table 4) The current expert consensus
document from the Society for Cardiac Angiography
and Interventions (SCAI) on appropriate use criteria
(AUC) for aortoiliac intervention are similar to the
current guidelines (95)

Treatment of TASC A B C and D Iliac Lesions) re-
ported 100 technical success in 325 patients with
aortoiliac lesions with a 24-month primary patency
rate of 879 (96) Neither TASC category nor lesion
length was predictive of restenosis These data
further support the endovascular-1047297rst strategy
regardless of TASC classi1047297cation and take into
consideration the evolution of devices (ie re-entry
catheters crossing devices and stents) which
improve success rates for the most complex lesions
COMMON FEMORAL DISEASE
Patients with common femoral artery (CFA) disease
are particularly symptomatic because the obstruction
not only occurs proximal to the super1047297cial femoral
artery (SFA) but also proximal to the deep femoralartery (profunda femoris) which is the major collat-
eral artery supplying blood to the lower limb when
there is SFA obstruction Traditionally common
femoral endarterectomy has been the CFA revascu-
larization procedure of choice (23) although
advances in endovascular therapy have shown some
promising results (97) A review of the National Sur-
gical Quality Improvement Program database for 2005
to 2010 found a combined mortality and morbidity
rate of 15 for common femoral endarterectomy
which was higher than expected (98) Patients
requiring CFA revascularization who are at increasedsurgical risk may be considered for less invasive
endovascular options
FEMORAL-POPLITEAL DISEASE
This segment begins at the bifurcation of the CFA into
the SFA and the deep femoral (profunda femoris)
artery The SFA is subject to 1047298exion elongation
compression and torsion unlike any other lower-
extremity artery This complexity leads to many
challenges for endovascular technology but despite
this an endovascular-1047297rst approach is currently thestandard of therapy for the majority of lesions
becau se of the very high proce dural success rate and
low risk (3) Some of the most lengthy and complex
lesions (TASC D) are more approachable because of
the re-entry and crossing devices more experienced
operators drug-eluting stents (DES) (99100) and
drug-coated balloons (DCBs) (101ndash107) that promise
improved long-term patency for patients with clau-
dication (99100103105)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines and the AUC documentfrom the SCAI recommend revascularization in
femoral-popliteal lesions for patients with CLI or for
patients with claudication who have had a suboptimal
r espon se to a tr ial of e xer cise (Tab le 5) An
endovascular-1047297rst approach is recommended for
TASC A through C lesions and is a reasonable option
for TASC D lesions depending on the experience of
the operator the patientrsquos comorbidities and proce-
dure safety (Table 5) (2395)
The 2 guidelines are in con1047298ict over the use of
primary stent placement in the femoral-popliteal ar-
teries with the ACCAHA guideline giving it a Class III
recommendation (do not do) and the ESC guideline
making primary femoral stenting reasonable 1047297rst-line
therapy (Class IIa) for intermediate-length lesions
(108109) The current evidence from several ran-
domized controlled trials supports primary stenting
in intermediate-length femoral stenoses and occlu-
sions (108ndash110) The soon-to-be-published updatedACCAHA guidelines will readdress this issue In
current practice the standard is to primarily stent
intermediate to long SFA lesions
The ACCAHA guideline broadly lump stents
togetherwith atherectomy devicescryotherapy laser
and cutting balloons stating they may be useful as
salvage therapy (Class IIa) but also stating that their
effectiveness remains to proven (Class IIb) Stents
should be removed from this group because their
effectiveness has been established in intermediate-
length femoral lesions Other than the use of the cut-
ting balloon and rotational atherectomy in lesions thatare resistant to dilation there is no comparative

evidence suggesting that the more expensive athe-
rectomy devices cryoplasty or laser angioplasty
should be preferred over conventional therapy
(percutaneous transluminal angioplasty [PTA] and
bare- metal stents [BMS] ) The ESC guideline disti n-
guishes bare-metal self-expanding stents from
adjunctive devices such as atherectomy devices cit-
i ng the p roven bene1047297t of BMS over PTA in
intermediate-length femoral-popliteal lesions
CLINICAL TRIAL UPDATE Three randomized controlledtrials of self-expanding BMS compared with PTA have
shown that the advantage for primary stenting is
related to lesion length For relatively discrete lesions
(mean 45 mm) (110) there was no advantage for pri-
mary stent placement however 2 other trials
(108109) with longer lesions (gt70 mm) showed a
signi1047297cant patency and functional bene1047297t for primary
femoral-popliteal BMS (Figure 3 Table 6) The proce-
dural success rate of endovascular therapy in
femoral-popliteal lesions is very high but in stable
limb ischemia durable patency remains a barrier
Cilostazol has been shown to reduce 1-year restenosis by more than one-half (20 vs 49 p frac14 00001) in
intermediate-length (128 mm) femoral lesions treated
with self-expanding BMS (114) These results need to
be con1047297rmed before this can be recommended as
standard therapy
Recent randomized controlled trials demonstrating
bene1047297t f or DE S (99100) DC B (103105106) and
covered stents (115ndash117) in femoral-popliteal arteries
will likely result in a change in the guidelines and
indications (Table 6 Figure 3)
There hasbeen some enthusiasm for self-expanding
covered (expanded polytetra1047298uoroethylene) stent
grafts in complex or lengthy femoral-popliteal seg-
ments Two randomized trials comparing covered
stents to BMS had divergent results One showed a
bene1047297t for 2-year primary patency but no difference in
target-lesion revascularization (TLR) or clinical out-
comes (116) whereas the other in longer (gt8 cm) le-
sions found no difference for primary patency (115ndash
117) When covered stents were compared with
above-the-knee femoral bypass with synthetic graft
material in a broad range of SFA lesion types (TASC A
thru D) no difference was found in the 4-year primary
patency between the 2 options (118)
The Zilver paclitaxel-eluting self-expanding DES
was superior to PTA in a randomized femoral-
popliteal trial with 1-year patency rates of 831 for
primary DES and 328 for PTA (p lt 0001) (Figure 3
Table 6) (99) There was also a 1-year patency
advantage for provisional DES after failed PTA
(899) compared with provisional BMS (730
p frac14 001) The bene1047297t was sustained at 2 years with
primary patency for the DES (748) signi1047297cantly
better t han PTA (265 p lt 001) (100) To date there
has been no head-to-head comparison of primary DES
to either BMS or DCB in femoral-popliteal arteries
but Zelle r et al (104) published a propensity scorendash
based compar ison of DES and DCB in conse cutive
patients with TASC C and D long (gt10 cm) lesions and
found no signi1047297cant differences in 1-year patency
(Figure 3 Table 6)
DCBs offer the promise of improved patency with areduced need for stents This is particularly important
in the dynamic environment of the super1047297cial femoral
and popliteal arteries where mechanical fatigue may
lead to stent fracture and increased risk of in-stent
restenosis Each DCB is unique with respect to the
paclitaxel dose (varying from 2 to 35 mgmm2) the
carrier molecule (excipient) the balloon material and
the coating technology used Superiority for paclitaxel
DCB over PTA was 1047297rst reported in 2008 (101102)
(Figure 3 Table 6) Subsequently new DCBs have
emerged including the INPACT (105106111113) and
the Lutonix (103106) balloons both of which showedclinical superiority to PTA in femoral-popliteal lesions

TLR and similar functional status improvement with
fewer repeat interventions Five-year follow-up

TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

For individuals with combined in1047298ow andout1047298ow disease with CLI in1047298ow lesionsshould be addressed 1047297rst (Class I Level
of Evidence C)
For patients with limb-threatening lower-extremity ischemia and an estimated lifeexpectancy 2 years in whom anautogenous vein conduit is not availableballoon angioplasty is reasonable toperform when possible as the initialprocedure to improve distal blood 1047298ow(Class IIa Level of Evidence B)
For infrapopliteal lesionsangioplasty is the preferredtechnique and stentimplantation should beconsidered only in the caseof insuf 1047297cient PTA (Class IIa

The effectiveness of uncoateduncoveredstents atherectomy cutting balloonsthermal devices and lasers for thetreatment of infrapopliteal lesions(except to salvage a suboptimal resultfrom balloon dilation) is not wellestablished (Class IIb Level of
Evidence C)
When revascularization in theinfrapopliteal segment isindicated the endovascular-1047297rst strategy should beconsidered (Class IIa Level
of Evidence C)
Primary stent placement is not recommendedin the femoral popliteal or tibial arteries(Class III Level of Evidence C)
Surgical and endovascular intervention is notindicated in patients with severedecrements in limb perfusion (egABI lt04) in the absence of clinicalsymptoms of CLI (Class III Level of

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

reducing variation Accreditation for Cardiovascular
Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous
improvement Payers and regulators should require
or reward independent accreditation to support
value-based health care
CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

and QOL but by very different mechanisms Revascu-
larization primarily improves exercise blood 1047298ow
whereas exercise training does not (29) In contrast
exercise training induces a variety of adaptive re-
sponses including improved skeletal muscle mito-
chondrial oxidative metabolismimproved endothelialfunction and more ef 1047297cient biomechanics of walking
Thus the obvious ldquo bestrdquo treatment strategy would
appear to be the combined program utilizing endo-
vascular revascularization and an optimal home-based
and long-term exercise program This hypothesis
was initially tested more than 25 years ago and the
combination of bypass surgery and exercise training
was superior to either treatment alone (54)
The CLEVER (Claudication Exercise Versus Endo-
luminal Revascularization) study was an important
and well-designed comparative effectiveness trial
that compared the outcomes for stenting of aortoiliacdisease with SE on a background of optimal medical
therapy in both groups (52) At the initial 6-month
follow up the primary endpoint of peak walking
time on a graded treadmill test was signi1047297cantly
improved in both the exercise and stent groups
compared with optimal medical management but the
peak walking time was signi1047297cantly higher in the
exercise group than in the stent group (52) The sec-
ondary endpoints were changes in responses to QOL
questionnaires Both of these patient-reported out-
comes were improved with exercise or stenting over
optimal medical management however improve-
ments tended to be greater in the stenting group The
same endpoints were measured at 18 months of
follow-up (55) In 79 of 119 patients who completed
the study improvements in treadmill peak walking
time remained for both the exercise and stenting
groups over optimal medical therapy but the differ-
ences in peak walking time between the exercise and
stenting groups were no longer statistically signi1047297-
cant Improved patient-reported outcomes remained
for both the exercise and stent groups
CLEVER clearly established the independent long-
term and broad-based bene1047297ts of both exercise
training and stent revascularization in symptomatic
PAD Similar to many such trials of the nearly 1000
patients evaluated only 11 were randomized and
fewer were available for 18-month follow-up Unfor-
tunately the arm of CLEVER that would have tested
the combination of exercise plus stenting was drop-
ped because of poor enrollment
In the recently published ERASE (Endovascular
Revascularization and Supervised Exercise) trial
106 patients were randomized to both endovascular
therapy and SE and 106 patients to SE alone (56) After
1 year the combination group had greater improve-
ment in maximum walking distance (MWD) and
health-related QOL scores than the group randomized
to SE alone however both groups demonstrated
dramatic improvement in MWD pain-free walking
distance and QOL The supervised exercise group
increased MWD from 285 m to 1240 m for animprovement of 955 m The combination group
increased MWD from 264 m to 1501 m for an
improvement of 1237 m This study illustrates
2 important points 1) the combinationof endovascular
therapy and SE is the most effective therapy for many
patients with claudication and 2) even the group
randomized to SE alone showed marked improvement
in MWD pain-free walking distance and QOL (56)
The cost of therapy must also be considered when
planning a particular strategy to treat symptomatic
PAD In a single-center Dutch randomized trial
endovascular revascularization had similar bene1047297t but highe r total mean cumula tive costs per patie nt
T A B L E 1 A Practical Home Exercise Program for Patients
With PAD
Frequency
3-5 days per week
Modality
Treadmill (this program can be adapted for walking outside)
Method
1 Begin at 2 mph and a grade of 0 (1047298at)
2 Try not to hold onto the treadmill Use the side panels for balanceonly
3 Stop the treadmill completely when pain is 3ndash4 on claudicationdiscomfort scale
4 When the discomfort has ceased resume exercise at the sameintensity
5 Repeat restexercise cycles
6 Progress to a higher workload when you can walk for 8 minwithout having to stop for leg symptoms
a) Increase speed by 02 mph each time you can walk for 8 min
b) Once you are able to walk at 34 mph or reach a speed at whichyou can no longer keep up begin increasing the grade by 1
Duration
The total exercise period including rest periods should equal45 min per day
Tips for success
1 Do not continue walking past 3ndash4 on claudication paindiscomfortscale This way the paindiscomfort should go away in 2ndash5 min If you walk until you are in severe pain you will build up lactic acidin your muscles and it will take much longer for the pain to goaway
2 When at 3ndash4 on paindiscomfort scale stop walking completelyDo not slow down but stop and stand on the treadmill until thediscomfort is gone
This works if you do it Not only will this improve your walkingperformance decrease your discomfort and improve your
quality of life this type of program is also bene1047297cial for yourheart blood pressure and lipid (cholesterol and triglyceride)levels

compared with a hospital-based exercise program
(57) Another study from a Dutch health-care databaseof 4954 patients demonstrated that a stepped
approach of exercise therapy followed by endovas-
cular revascularization was more cost-effective than
revascularization only (58)
Thus future studies should address not only the
clinical bene1047297ts but also the effectiveness of the
combination of an exercise program and limb revas-
cularization In this context effectiveness pertains to
the ability of a treatment program to be utilized by a
majority of appropriate patients in a community and
to achieve high adherence to the program as well as
that the desired improvements in functional out-comes are obtained
OPTIMAL MEDICAL THERAPY FOR
PATIENTS WITH PAD
Medical therapy for PAD should address treatment for
limb-related outcomes (improve claudication symp-
toms and prevent CLI and amputation) and treatment
to prevent major adverse cardiovascular events
(MACE myocardial infarction stroke and cardio-
vascular death) (Central Illustration)
Despite the recommendations from societal
guidelines on the management of patients with PAD(2) these patients continue to be undertreated
compared with patients with CAD (859) Adherence
to these guidelines in real-world practice is associatedwith improved outcomes (Figure 1) which empha-
sizes the bene1047297t of multifactorial risk reduction in
this high-risk population (12) Performance measures
for PAD will help improve quality of care and may be
incorporated into future quality metrics (60)
SMOKING CESSATION
Smoking is a major risk factor for the developmentand
progression of PAD A multidisciplinary approach to
smoking cessation should be used including group-
based programs and cognit ive beha viora l therapy
A recent study evaluated the association betweensuccessful quitting after endovascular intervention
and long-term outcomes (61) Among 739 patients
undergoing lower-extremity angiography 28 were
active smokers at the time of endovascular interven-
tion In the subsequent year 30 of active smokers
successfully quit Those who remained off tobacco
had signi1047297cantly lower 5-year mortality (14 vs 31)
and improved amputation-free survival (81 vs
60) Discontinuation of smoking is the most
important lifestyle modi1047297cation in preventing CLI
amputation and MACE in patients with PAD This
needs to be conveyed to the patient in an empatheticand nonjudgmental way during every of 1047297ce visit The

VAPOR (Vascular Physician Offer and Report) trial is
currently evaluating methods to improve physician-
patient interactions to encourage patients with PAD
to abstain from smoking (62)
PHARMACOTHERAPY TO IMPROVE
CLAUDICATION SYMPTOMS
Cilostazol is a type III phosphodiesterase inhibitorwith a number of properties but the mechanism by
which cilostazol improves claudication is not known
(63) A pooled analysis of all of the randomized
trials shows an improvement in absolute claudica-
tion distance of approximately 50 compared with
placebo (64) Although cilostazol appears to be safe
for long-term administration adherence is low (gt60
discontinuation at 3 years) because of adverse effects
including headache palpitations and diarrhea (65)
Because of its mechanistic similarity to other type III
phosphodiesterase inhibitors such as milrinone cil-
ostazol is contraindicated in patients with a history of
heart failure The optimal dose of cilostazol is 100 mg
twice daily and it may take up to 4 months to derive
maximum bene1047297t from this drug (63)
Pentoxifylline is rarely used today to treat claudi-
cation because of a lack of ef 1047297cacy compared with
cilostazol Naftidrofuryl is a 5-HT2 antagonist that is
approved in Europe In a pooled analysis involving
888 patients randomized to naftidrofuryl there was a
26 increase in pain-free walking compared with
placebo (66) It is not available for use in the United
States
ACEIs
ACEIs are associated with a signi1047297cant reduction in
MACE among patients with PAD These data are
derived primarily from the HOPE (Heart Outcomes
Prevention Evaluation) trial which randomized 9297
high-risk patients with vascular disease or diabetes
plus 1 other risk factor to ramipril 10 mg daily
or placebo Among these 1966 patients with PAD
(423) were randomized to ramipril and 2085
(448) to placebo The primary outcome (myocardial
infarction stroke cardiovascular death) occurred in
143 of those without PAD versus 220 of those
with PAD (67) In the 5231 patients without PAD the
primary outcome was observed in 126 in the ram-
ipril group and 149 in the placebo arm In those with
an ABI lt06the primary outcome occurred in 164 in
the ramipril arm versus 22 in the placebo arm Thecardiovascular bene1047297t of ramipril applies to patients
with both asymptomatic and symptomatic PAD across
a broad range of ABI values (68) Similar results have
also been observed with telmisartan which suggests a
possible class effect of ACEIangiotensin receptor
blockade among patients with PAD (6970)
STATINS
High-intensity statin medications are recommended
for a ll pa ti ents with PAD on the basis of the
most recent American College of Cardiology (ACC)American Heart Association (AHA) guidelines which

emphasize cardiovascular risk over low-density lipo-
protein targets (71) The majority of the data in sup-
port of statin use in patients with PAD are derived
from subset analysis of larger clinical trials The
Medical Research CouncilBritish Heart Foundationrsquos
Heart Protection Study randomized 20536 high-risk
patients to simvastatin 40 mg daily or placebo (72)
All-cause mortality occurred in 129 of patients
randomized to simvastatin and 147 randomized to
placebo (22 relative risk reduction p frac14 00003)
Observational studies have also con1047297rmed the car-
diovascular and overall mortality bene1047297t of statins
among patients with more advanced PAD including
CLI (73)
Recent data suggest that statin use is also associ-
ated with a reduction in adverse limb outcomes
including amputation In the REACH (Reduction of
Atherothrombosis for Continued Health) registry
statin therapy was associated with a signi1047297cant
reduction in the combined endpoint of worsening
claudication new CLI new revascularization or
amputation (74) The absolute 4-year event rates were
220 versus 262 which emphasizes the highrate of
adverse limb events among patients with symptom-
atic PAD Importantly statin therapy was also associ-
ated with a signi1047297cant reduction in 4-year rates of
ischemic amputation (38 vs 56) In an analysis of
Medicare claims data of patients undergoing lower-
extremity revascularization statin use was associ-
ated with lower rates of amputation at 30 days
90 days and 1 year (75) Single-center observational
data among patients with CLI suggest that statin
therapy is also associated with improved 1-year rates
of primary patency secondary patency and improved
limb salvage after endovascular intervention (73)
Patients with PAD should be prescribed a high-
intensity statin to reduce the risk of cardiovascular
events In most studies the rates of statin prescrip-
tion were lt75 which emphasizes the importance of
maximizing medical therapy among this high-risk
group of patients with advanced atheroscleroticdisease (59)
ANTIPLATELET THERAPY
ASPIRIN Aspirin has been a mainstay of drug ther-
apy among patients with PAD however the data
supporting aspirin use in patients with PAD have not
been well subst antia ted (7677)
Recent studies investigating the bene1047297t of aspirin
among patients with asymptomatic PAD have yielded
negative results Both the POPADAD (Prevention of
Progression of Arterial Disease and Diabetes) trial and
the AAA (Aspirin for Asymptomatic Atherosclerosis)
trial compared low-dose aspirin with placebo in
patients with a low ABI Neither study demonstrated
a reduction in fatal and nonfatal cardiovascular
events or revascularization with aspirin mono-
therapy although both notably included low-risk
patients with borderline ABI (099 in POPADAD
and 095 in AAA) (7778)
Consistent with these results a meta-analysis
speci1047297cally examined aspirin for PAD in 18 trials
involving 5269 patients In patients taking aspirin
monotherapy there was a nonsigni1047297cant reduction
in cardiovascular events (absolute event rate 82
vs 96 relative risk 075 95 con1047297dence inter-
val [CI] 048 to 118) however there was a sig-
ni1047297cant reduction in nonfatal stroke (HR 064 95
CI 042 to 099 p frac14 004) (76) In the last iteration
of the PAD guidelines (2) aspirin was a Class I
Level of Evidence A recommendation among pa-
tients with symptomatic PAD a Class IIa recom-
mendation among patients with asymptomatic PAD
and an ABI lt090 and a Class IIb indication among
asymptomatic patients with an ABI of 090 to 099
(2) Some of these recommendations may change in
the upcoming revision of the ACCAHA PAD prac-
tice guidelines
CLOPIDOGREL AND
DUAL-ANTIPLATELET THERAPY
Clopidogrel is indicated as an alternative to aspirin
for antiplatelet monotherapy among patients with
PAD although recent studies suggest that lt20 of
patients with PAD are prescribed clopidogrel in clin-
ical practice (79) The data supporting clopidogrel use
are primarily based on the CAPRIE (Clopidogrel
Versus Aspirin in Patients at Risk of Ischaemic
Events) study in which clopidogrel monotherapy was
associated with a small bene1047297t compared with aspirin
325 mg daily in the overall population but there was a
238 relative risk reduction among the subgroup of
patients with symptomatic PAD (n frac14 6452 absolute
event rate 37 vs 49 per year) (80)
Dual-antiplatelet therapy (DAPT) with low-dose
aspirin (75 to 162 mg daily) and clopidogrel 75 mg
daily was studied in the CHARISMA (Clopidogrel for
High Atherothrombotic Risk and Ischemic Stabiliza-
tion Management and Avoidance) trial which
included patients at high risk for atherothrombotic
events The overall results of this trial were not sig-
ni1047297cant although in subgroup analyses there was a
bene1047297t of DAPT among patients with symptomatic
atherothrombosis (81) In an analysis of the 3096 pa-
tients in the trial with PAD DAPT was associated with
a lower rate of myocardial infarction (23 vs 37

ization for ischemic events (165 vs 201 HR 081
95 CI 068 to 095 p frac14 0011) but not the overall
composite primary endpoint (82) There was no dif-
ference between the groups in moderate severe or
fatal bleeding but there was an increase in minor
bleed ing i n th e DAPT group
In a recent propensity-matched observational
study among patients undergoing endovascular
intervention there was a signi1047297cant reduction in
MACE among patients taking DAPT (adjusted HR
065 95 CI 044 to 096 p frac14 003) compared with
those taking aspirin monotherapy (83) The discor-
dant 1047297ndings between this study and the CHARISMA
trial may be explained by inclusion of a cohort
with more advanced atherosclerotic disease under-
going endovascular intervention including gt50 of
patients with CLI
The CASPAR (Clopidogrel and Acetylsalicylic Acid
in Bypass Surgery for Peripheral Arterial Disease) trial
studied DAPT versus aspirin 75 to 100 mg daily among
patients undergoing below-knee surgical bypass for
treatment of CLI (84) The primary endpoint of death
major amputation index-graft occlusion or revascu-
larization was not different for DAPT versus
acetylsalicylic acid (ASA) monotherapy In a pre-
speci1047297ed subgroup analysis there was a signi1047297cant
bene1047297t of DAPT in patients treated with prosthetic
grafts (HR 065 95 CI 045 to 095 p frac14 0025) but
not in those treated with vein grafts A similar trial
the CAMPER study (Clopidogrel and Aspirin in the
Management of peripheral Endovascular Revascular-
ization) tested DAPT versus aspirin in patients un-
dergoing infrainguinal endovascular therapy The
study was never completed because of poor enroll-
ment (doctors would not randomize patients to ASA
alone) continued funding could not be justi1047297ed
DAPT is often prescribed after endovascular inter-
vention although the data supporting duration of
DAPTare sparseIn practice most physicians prescribe
DAPTfor a time periodrangingfrom1 to3 monthspost-intervention The ASPIRE-PAD study (Antiplatelet
Strategy for Peripheral Arterial Interventions for
Revascularization of Lower Extremities) is currently
evaluating comparative outcomes of 1 versus 12
months of DAPT after endovascular intervention (85)
VORAPAXAR
Thrombin acts through platelets via a unique mecha-
nism binding of the protease activating receptor-1
(PAR-1) a G protein-coupled receptor expressed on
the platelet surface leads to receptor activation
and increased intracellular Ca2thorn cyclic adenosine
monophosphate (cAMP) levels subsequently decrease
which leads to increased platelet aggregation and
releaseof further activatingfactors Vorapaxar inhibits
PAR-1 thereby signi1047297cantly reducing thrombin-
mediated platelet activation
T he T RA 2P-TIMI 50 trial (Thrombin Receptor
Antagonist for Secondary PreventionndashThrombolysis
in Myocardial Infarction Study Group) studied vor-
apaxar sulfate 25 mg daily versus placebo (ASA and
or clopidogrel therapy at the investigatorsrsquo discre-
tion) among 26449 patients with a recent myocardial
infarction recent ischemic stroke or symptomatic
PAD At 3 years there was a signi1047297cant reduction in
the primary endpoint of MACE (absolute event rates
93 vs 105 HR 087 95 CI 080 to 094
p lt 0001) (79) After 2 years the data and safety
monitoring board recommended stopping the study
drug in the patient subgroup entered with prior
ischemic stroke because of an increased risk of
intracranial hemorrhage Among the 3787 patients
with PAD the majority were treated with aspirin
monotherapy plus vorapaxar or placebo The reduc-
tion in MACE was not statistically signi1047297cant in those
assigned to vorapaxar (absolute event rates 113 vs
119 HR 094 95 CI 078 to 114) Similarly
negative results were observed among patients with
PAD who were enrolled in the TRACER (Thrombin
Receptor Antagonist for Clinical Event Reduction in
Acute Coronary Syndrome) trial (86) Additionally
vorapaxar is associated with a signi1047297cantly increased
risk of major bleeding However in both of these
trials there were relatively few MACE in the PAD
subgroup The PAD group was underpowered to draw
any conclusions on ef 1047297cacy
Pre-speci1047297ed analysis of limb-related outcomes in
the TRA 2P-TIMI 50 trial demonstrated that patients
assigned to vorapaxar had signi1047297cantly reduced rates
of acute limb ischemia (23 vs 39 HR 058 95
CI 039 to 086 p frac14 0006) as well as peripheral
artery revascularization (184 vs 222 HR 084
95 CI 073 to 097 p frac14 0017) during the 3-yearfollow-up (Figure 2) (87) These ef 1047297cacy endpoints
must be balanced by a signi1047297cantly increased rate of
major bleeding among patients prescribed vorapaxar
Further research into the mechanism by which
vorapaxar led to improved limb outcomes is required
to fully understand these effects
CELL-BASED AND ANGIOGENIC THERAPIES
Modulation and enhancement of lower-extremity
blood 1047298ow via angiogenesis arteriogenesis or vas-
culogenesis could provide a promising breakthrough
therapy for patients with PAD (88) Additionally

there has been much interest in the use of stem cellndash
derived endothelial cells or modi1047297cation of resident
stem cells (89) Potential bene1047297ts of these therapies
include improved wound healing and limb salvage
among patients with CLI as well as improved clau-
dication distance To date numerous cell-based and
angiogenic therapies have been tested and despite
promising results in early clinical trials none of these
agents have shown bene1047297t in larger trials
ONGOING CLINICAL TRIALS
There are currently 2 clinical trials studying novel
antiplatelet and anticoagulant agents to reduce MACE
and potentially modify limb-related outcomes
EUCLID (Study Comparing Cardiovascular Effects of
Ticagrelor and Clopidogrel in Patients With Periph-eral Artery Disease) is a randomized blinded double-
dummy trial comparing ticagrelor 90 mg twice daily
to clopidogrel monotherapy among 13500 patients
with PAD (90) All patients are tested for clopidogrel
resistance before randomization The primary
endpoint is a composite of MACE and results are
expected in late 2016 The COMPASS (Rivaroxaban for
the Prevention of Major Cardiovascular Events in
Coronary or Peripheral Artery Disease) trial is evalu-
ating low-dose rivaroxaban alone versus placebo
aspirin alone or rivaroxaban and aspirin among
21400 patients with a history of myocardial infarc-tion or PAD the primary endpoint of this trial is a
composite of MACE (91)
ENDOVASCULAR THERAPY
Endovascular revascularization plays a key role in the
management of patients with PAD Patients with sta-
ble cl audication have a low ris k of lim b loss but may be
severely limited by their symptoms In most circum-
stances patients with claudication should be offered a
trial of cilostazol and an exercise program as initial
therapy If the patient is not satis1047297ed after a trial of
medical therapy endovascular revascularization can be consi dere d Patie nts with CLI require more urgent
revascularization because of an increased riskof tissue
loss and amputation as well as an extremely high risk
of cardiovascular events (92)
There are 2 well-established classi1047297cation schemes
to describe the severity of PAD The 1047297rst is a func-
tional assessment (Fontaine or Rutherford classi1047297ca-
tion [RC]) (Table 2) and the second is an anatomic
lesion classi1047297cation (Trans-Atlantic Inter-Society
Consensus [TASC]) (Table 3) (45) In addition there
has been recent interest in the angiosome concept in
helping to in1047298uence optimal revascularization stra-tegies for limb salvage (93) An angiosome is an
anatomic unit of tissue (consisting of skin subcu-
taneous tissue fascia muscle and bone) that is fed
by a source arte ry and drai ned by speci1047297c veins
If the patient is a candidate for either endovascular
or open surgery the less invasive option (ie an
endovascular-1047297rst strategy) is the current standard of
care The selection of a complex lesion (TASC D) for
endovascular therapy will vary with the skill and
experience of the interventionalist The goal in
treating a patient who has functional impairment
because of claudi cation is dura ble relief of symptoms
In patients with CLI and a threatened limb or tissueloss the goal is rapid reperfusion of the ischemic

AORTOILIAC OCCLUSIVE DISEASE
There has been a practice shift over the past 25 years
as the treatment of aortoiliac disease transitioned
from open surgery with aortobiiliac or aortobifemoral
bypass to endovascular trea tment s for comple x and
diffuse disease (TASC D) This preference for less
invasive therapy is evidence based and driven by
shorter length of stay (or treatment as an outpatient
entirely) and lower periprocedural morbidity and
mortality rates while achieving comparable patency
rates (4- to 5-year primary patency of 60 to 86
with secondary patency rates of 80 to 98) (94)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) In 2011 the European Society of Car-
diology (ESC) (3) and ACCAHA PAD guidelines (2)
recommended an endovascular-1047297rst approach for
aortoiliac lesions recommended that borderline
lesions be assessed with hemodynamic gradients and
supported primary stent placement in the aortoiliac
arteries (Table 4) The current expert consensus
document from the Society for Cardiac Angiography
and Interventions (SCAI) on appropriate use criteria
(AUC) for aortoiliac intervention are similar to the
current guidelines (95)

Treatment of TASC A B C and D Iliac Lesions) re-
ported 100 technical success in 325 patients with
aortoiliac lesions with a 24-month primary patency
rate of 879 (96) Neither TASC category nor lesion
length was predictive of restenosis These data
further support the endovascular-1047297rst strategy
regardless of TASC classi1047297cation and take into
consideration the evolution of devices (ie re-entry
catheters crossing devices and stents) which
improve success rates for the most complex lesions
COMMON FEMORAL DISEASE
Patients with common femoral artery (CFA) disease
are particularly symptomatic because the obstruction
not only occurs proximal to the super1047297cial femoral
artery (SFA) but also proximal to the deep femoralartery (profunda femoris) which is the major collat-
eral artery supplying blood to the lower limb when
there is SFA obstruction Traditionally common
femoral endarterectomy has been the CFA revascu-
larization procedure of choice (23) although
advances in endovascular therapy have shown some
promising results (97) A review of the National Sur-
gical Quality Improvement Program database for 2005
to 2010 found a combined mortality and morbidity
rate of 15 for common femoral endarterectomy
which was higher than expected (98) Patients
requiring CFA revascularization who are at increasedsurgical risk may be considered for less invasive
endovascular options
FEMORAL-POPLITEAL DISEASE
This segment begins at the bifurcation of the CFA into
the SFA and the deep femoral (profunda femoris)
artery The SFA is subject to 1047298exion elongation
compression and torsion unlike any other lower-
extremity artery This complexity leads to many
challenges for endovascular technology but despite
this an endovascular-1047297rst approach is currently thestandard of therapy for the majority of lesions
becau se of the very high proce dural success rate and
low risk (3) Some of the most lengthy and complex
lesions (TASC D) are more approachable because of
the re-entry and crossing devices more experienced
operators drug-eluting stents (DES) (99100) and
drug-coated balloons (DCBs) (101ndash107) that promise
improved long-term patency for patients with clau-
dication (99100103105)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines and the AUC documentfrom the SCAI recommend revascularization in
femoral-popliteal lesions for patients with CLI or for
patients with claudication who have had a suboptimal
r espon se to a tr ial of e xer cise (Tab le 5) An
endovascular-1047297rst approach is recommended for
TASC A through C lesions and is a reasonable option
for TASC D lesions depending on the experience of
the operator the patientrsquos comorbidities and proce-
dure safety (Table 5) (2395)
The 2 guidelines are in con1047298ict over the use of
primary stent placement in the femoral-popliteal ar-
teries with the ACCAHA guideline giving it a Class III
recommendation (do not do) and the ESC guideline
making primary femoral stenting reasonable 1047297rst-line
therapy (Class IIa) for intermediate-length lesions
(108109) The current evidence from several ran-
domized controlled trials supports primary stenting
in intermediate-length femoral stenoses and occlu-
sions (108ndash110) The soon-to-be-published updatedACCAHA guidelines will readdress this issue In
current practice the standard is to primarily stent
intermediate to long SFA lesions
The ACCAHA guideline broadly lump stents
togetherwith atherectomy devicescryotherapy laser
and cutting balloons stating they may be useful as
salvage therapy (Class IIa) but also stating that their
effectiveness remains to proven (Class IIb) Stents
should be removed from this group because their
effectiveness has been established in intermediate-
length femoral lesions Other than the use of the cut-
ting balloon and rotational atherectomy in lesions thatare resistant to dilation there is no comparative

evidence suggesting that the more expensive athe-
rectomy devices cryoplasty or laser angioplasty
should be preferred over conventional therapy
(percutaneous transluminal angioplasty [PTA] and
bare- metal stents [BMS] ) The ESC guideline disti n-
guishes bare-metal self-expanding stents from
adjunctive devices such as atherectomy devices cit-
i ng the p roven bene1047297t of BMS over PTA in
intermediate-length femoral-popliteal lesions
CLINICAL TRIAL UPDATE Three randomized controlledtrials of self-expanding BMS compared with PTA have
shown that the advantage for primary stenting is
related to lesion length For relatively discrete lesions
(mean 45 mm) (110) there was no advantage for pri-
mary stent placement however 2 other trials
(108109) with longer lesions (gt70 mm) showed a
signi1047297cant patency and functional bene1047297t for primary
femoral-popliteal BMS (Figure 3 Table 6) The proce-
dural success rate of endovascular therapy in
femoral-popliteal lesions is very high but in stable
limb ischemia durable patency remains a barrier
Cilostazol has been shown to reduce 1-year restenosis by more than one-half (20 vs 49 p frac14 00001) in
intermediate-length (128 mm) femoral lesions treated
with self-expanding BMS (114) These results need to
be con1047297rmed before this can be recommended as
standard therapy
Recent randomized controlled trials demonstrating
bene1047297t f or DE S (99100) DC B (103105106) and
covered stents (115ndash117) in femoral-popliteal arteries
will likely result in a change in the guidelines and
indications (Table 6 Figure 3)
There hasbeen some enthusiasm for self-expanding
covered (expanded polytetra1047298uoroethylene) stent
grafts in complex or lengthy femoral-popliteal seg-
ments Two randomized trials comparing covered
stents to BMS had divergent results One showed a
bene1047297t for 2-year primary patency but no difference in
target-lesion revascularization (TLR) or clinical out-
comes (116) whereas the other in longer (gt8 cm) le-
sions found no difference for primary patency (115ndash
117) When covered stents were compared with
above-the-knee femoral bypass with synthetic graft
material in a broad range of SFA lesion types (TASC A
thru D) no difference was found in the 4-year primary
patency between the 2 options (118)
The Zilver paclitaxel-eluting self-expanding DES
was superior to PTA in a randomized femoral-
popliteal trial with 1-year patency rates of 831 for
primary DES and 328 for PTA (p lt 0001) (Figure 3
Table 6) (99) There was also a 1-year patency
advantage for provisional DES after failed PTA
(899) compared with provisional BMS (730
p frac14 001) The bene1047297t was sustained at 2 years with
primary patency for the DES (748) signi1047297cantly
better t han PTA (265 p lt 001) (100) To date there
has been no head-to-head comparison of primary DES
to either BMS or DCB in femoral-popliteal arteries
but Zelle r et al (104) published a propensity scorendash
based compar ison of DES and DCB in conse cutive
patients with TASC C and D long (gt10 cm) lesions and
found no signi1047297cant differences in 1-year patency
(Figure 3 Table 6)
DCBs offer the promise of improved patency with areduced need for stents This is particularly important
in the dynamic environment of the super1047297cial femoral
and popliteal arteries where mechanical fatigue may
lead to stent fracture and increased risk of in-stent
restenosis Each DCB is unique with respect to the
paclitaxel dose (varying from 2 to 35 mgmm2) the
carrier molecule (excipient) the balloon material and
the coating technology used Superiority for paclitaxel
DCB over PTA was 1047297rst reported in 2008 (101102)
(Figure 3 Table 6) Subsequently new DCBs have
emerged including the INPACT (105106111113) and
the Lutonix (103106) balloons both of which showedclinical superiority to PTA in femoral-popliteal lesions

TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

reducing variation Accreditation for Cardiovascular
Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous
improvement Payers and regulators should require
or reward independent accreditation to support
value-based health care
CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

compared with a hospital-based exercise program
(57) Another study from a Dutch health-care databaseof 4954 patients demonstrated that a stepped
approach of exercise therapy followed by endovas-
cular revascularization was more cost-effective than
revascularization only (58)
Thus future studies should address not only the
clinical bene1047297ts but also the effectiveness of the
combination of an exercise program and limb revas-
cularization In this context effectiveness pertains to
the ability of a treatment program to be utilized by a
majority of appropriate patients in a community and
to achieve high adherence to the program as well as
that the desired improvements in functional out-comes are obtained
OPTIMAL MEDICAL THERAPY FOR
PATIENTS WITH PAD
Medical therapy for PAD should address treatment for
limb-related outcomes (improve claudication symp-
toms and prevent CLI and amputation) and treatment
to prevent major adverse cardiovascular events
(MACE myocardial infarction stroke and cardio-
vascular death) (Central Illustration)
Despite the recommendations from societal
guidelines on the management of patients with PAD(2) these patients continue to be undertreated
compared with patients with CAD (859) Adherence
to these guidelines in real-world practice is associatedwith improved outcomes (Figure 1) which empha-
sizes the bene1047297t of multifactorial risk reduction in
this high-risk population (12) Performance measures
for PAD will help improve quality of care and may be
incorporated into future quality metrics (60)
SMOKING CESSATION
Smoking is a major risk factor for the developmentand
progression of PAD A multidisciplinary approach to
smoking cessation should be used including group-
based programs and cognit ive beha viora l therapy
A recent study evaluated the association betweensuccessful quitting after endovascular intervention
and long-term outcomes (61) Among 739 patients
undergoing lower-extremity angiography 28 were
active smokers at the time of endovascular interven-
tion In the subsequent year 30 of active smokers
successfully quit Those who remained off tobacco
had signi1047297cantly lower 5-year mortality (14 vs 31)
and improved amputation-free survival (81 vs
60) Discontinuation of smoking is the most
important lifestyle modi1047297cation in preventing CLI
amputation and MACE in patients with PAD This
needs to be conveyed to the patient in an empatheticand nonjudgmental way during every of 1047297ce visit The

PHARMACOTHERAPY TO IMPROVE
CLAUDICATION SYMPTOMS
Cilostazol is a type III phosphodiesterase inhibitorwith a number of properties but the mechanism by
which cilostazol improves claudication is not known
(63) A pooled analysis of all of the randomized
trials shows an improvement in absolute claudica-
tion distance of approximately 50 compared with
placebo (64) Although cilostazol appears to be safe
for long-term administration adherence is low (gt60
discontinuation at 3 years) because of adverse effects
including headache palpitations and diarrhea (65)
Because of its mechanistic similarity to other type III
phosphodiesterase inhibitors such as milrinone cil-
ostazol is contraindicated in patients with a history of
heart failure The optimal dose of cilostazol is 100 mg
twice daily and it may take up to 4 months to derive
maximum bene1047297t from this drug (63)
Pentoxifylline is rarely used today to treat claudi-
cation because of a lack of ef 1047297cacy compared with
cilostazol Naftidrofuryl is a 5-HT2 antagonist that is
approved in Europe In a pooled analysis involving
888 patients randomized to naftidrofuryl there was a
26 increase in pain-free walking compared with
placebo (66) It is not available for use in the United
States
ACEIs
ACEIs are associated with a signi1047297cant reduction in
MACE among patients with PAD These data are
derived primarily from the HOPE (Heart Outcomes
Prevention Evaluation) trial which randomized 9297
high-risk patients with vascular disease or diabetes
plus 1 other risk factor to ramipril 10 mg daily
or placebo Among these 1966 patients with PAD
(423) were randomized to ramipril and 2085
(448) to placebo The primary outcome (myocardial
infarction stroke cardiovascular death) occurred in
143 of those without PAD versus 220 of those
with PAD (67) In the 5231 patients without PAD the
primary outcome was observed in 126 in the ram-
ipril group and 149 in the placebo arm In those with
an ABI lt06the primary outcome occurred in 164 in
the ramipril arm versus 22 in the placebo arm Thecardiovascular bene1047297t of ramipril applies to patients
with both asymptomatic and symptomatic PAD across
a broad range of ABI values (68) Similar results have
also been observed with telmisartan which suggests a
possible class effect of ACEIangiotensin receptor
blockade among patients with PAD (6970)
STATINS
High-intensity statin medications are recommended
for a ll pa ti ents with PAD on the basis of the
most recent American College of Cardiology (ACC)American Heart Association (AHA) guidelines which

emphasize cardiovascular risk over low-density lipo-
protein targets (71) The majority of the data in sup-
port of statin use in patients with PAD are derived
from subset analysis of larger clinical trials The
Medical Research CouncilBritish Heart Foundationrsquos
Heart Protection Study randomized 20536 high-risk
patients to simvastatin 40 mg daily or placebo (72)
All-cause mortality occurred in 129 of patients
randomized to simvastatin and 147 randomized to
placebo (22 relative risk reduction p frac14 00003)
Observational studies have also con1047297rmed the car-
diovascular and overall mortality bene1047297t of statins
among patients with more advanced PAD including
CLI (73)
Recent data suggest that statin use is also associ-
ated with a reduction in adverse limb outcomes
including amputation In the REACH (Reduction of
Atherothrombosis for Continued Health) registry
statin therapy was associated with a signi1047297cant
reduction in the combined endpoint of worsening
claudication new CLI new revascularization or
amputation (74) The absolute 4-year event rates were
220 versus 262 which emphasizes the highrate of
adverse limb events among patients with symptom-
atic PAD Importantly statin therapy was also associ-
ated with a signi1047297cant reduction in 4-year rates of
ischemic amputation (38 vs 56) In an analysis of
Medicare claims data of patients undergoing lower-
extremity revascularization statin use was associ-
ated with lower rates of amputation at 30 days
90 days and 1 year (75) Single-center observational
data among patients with CLI suggest that statin
therapy is also associated with improved 1-year rates
of primary patency secondary patency and improved
limb salvage after endovascular intervention (73)
Patients with PAD should be prescribed a high-
intensity statin to reduce the risk of cardiovascular
events In most studies the rates of statin prescrip-
tion were lt75 which emphasizes the importance of
maximizing medical therapy among this high-risk
group of patients with advanced atheroscleroticdisease (59)
ANTIPLATELET THERAPY
ASPIRIN Aspirin has been a mainstay of drug ther-
apy among patients with PAD however the data
supporting aspirin use in patients with PAD have not
been well subst antia ted (7677)
Recent studies investigating the bene1047297t of aspirin
among patients with asymptomatic PAD have yielded
negative results Both the POPADAD (Prevention of
Progression of Arterial Disease and Diabetes) trial and
the AAA (Aspirin for Asymptomatic Atherosclerosis)
trial compared low-dose aspirin with placebo in
patients with a low ABI Neither study demonstrated
a reduction in fatal and nonfatal cardiovascular
events or revascularization with aspirin mono-
therapy although both notably included low-risk
patients with borderline ABI (099 in POPADAD
and 095 in AAA) (7778)
Consistent with these results a meta-analysis
speci1047297cally examined aspirin for PAD in 18 trials
involving 5269 patients In patients taking aspirin
monotherapy there was a nonsigni1047297cant reduction
in cardiovascular events (absolute event rate 82
vs 96 relative risk 075 95 con1047297dence inter-
val [CI] 048 to 118) however there was a sig-
ni1047297cant reduction in nonfatal stroke (HR 064 95
CI 042 to 099 p frac14 004) (76) In the last iteration
of the PAD guidelines (2) aspirin was a Class I
Level of Evidence A recommendation among pa-
tients with symptomatic PAD a Class IIa recom-
mendation among patients with asymptomatic PAD
and an ABI lt090 and a Class IIb indication among
asymptomatic patients with an ABI of 090 to 099
(2) Some of these recommendations may change in
the upcoming revision of the ACCAHA PAD prac-
tice guidelines
CLOPIDOGREL AND
DUAL-ANTIPLATELET THERAPY
Clopidogrel is indicated as an alternative to aspirin
for antiplatelet monotherapy among patients with
PAD although recent studies suggest that lt20 of
patients with PAD are prescribed clopidogrel in clin-
ical practice (79) The data supporting clopidogrel use
are primarily based on the CAPRIE (Clopidogrel
Versus Aspirin in Patients at Risk of Ischaemic
Events) study in which clopidogrel monotherapy was
associated with a small bene1047297t compared with aspirin
325 mg daily in the overall population but there was a
238 relative risk reduction among the subgroup of
patients with symptomatic PAD (n frac14 6452 absolute
event rate 37 vs 49 per year) (80)
Dual-antiplatelet therapy (DAPT) with low-dose
aspirin (75 to 162 mg daily) and clopidogrel 75 mg
daily was studied in the CHARISMA (Clopidogrel for
High Atherothrombotic Risk and Ischemic Stabiliza-
tion Management and Avoidance) trial which
included patients at high risk for atherothrombotic
events The overall results of this trial were not sig-
ni1047297cant although in subgroup analyses there was a
bene1047297t of DAPT among patients with symptomatic
atherothrombosis (81) In an analysis of the 3096 pa-
tients in the trial with PAD DAPT was associated with
a lower rate of myocardial infarction (23 vs 37

ization for ischemic events (165 vs 201 HR 081
95 CI 068 to 095 p frac14 0011) but not the overall
composite primary endpoint (82) There was no dif-
ference between the groups in moderate severe or
fatal bleeding but there was an increase in minor
bleed ing i n th e DAPT group
In a recent propensity-matched observational
study among patients undergoing endovascular
intervention there was a signi1047297cant reduction in
MACE among patients taking DAPT (adjusted HR
065 95 CI 044 to 096 p frac14 003) compared with
those taking aspirin monotherapy (83) The discor-
dant 1047297ndings between this study and the CHARISMA
trial may be explained by inclusion of a cohort
with more advanced atherosclerotic disease under-
going endovascular intervention including gt50 of
patients with CLI
The CASPAR (Clopidogrel and Acetylsalicylic Acid
in Bypass Surgery for Peripheral Arterial Disease) trial
studied DAPT versus aspirin 75 to 100 mg daily among
patients undergoing below-knee surgical bypass for
treatment of CLI (84) The primary endpoint of death
major amputation index-graft occlusion or revascu-
larization was not different for DAPT versus
acetylsalicylic acid (ASA) monotherapy In a pre-
speci1047297ed subgroup analysis there was a signi1047297cant
bene1047297t of DAPT in patients treated with prosthetic
grafts (HR 065 95 CI 045 to 095 p frac14 0025) but
not in those treated with vein grafts A similar trial
the CAMPER study (Clopidogrel and Aspirin in the
Management of peripheral Endovascular Revascular-
ization) tested DAPT versus aspirin in patients un-
dergoing infrainguinal endovascular therapy The
study was never completed because of poor enroll-
ment (doctors would not randomize patients to ASA
alone) continued funding could not be justi1047297ed
DAPT is often prescribed after endovascular inter-
vention although the data supporting duration of
DAPTare sparseIn practice most physicians prescribe
DAPTfor a time periodrangingfrom1 to3 monthspost-intervention The ASPIRE-PAD study (Antiplatelet
Strategy for Peripheral Arterial Interventions for
Revascularization of Lower Extremities) is currently
evaluating comparative outcomes of 1 versus 12
months of DAPT after endovascular intervention (85)
VORAPAXAR
Thrombin acts through platelets via a unique mecha-
nism binding of the protease activating receptor-1
(PAR-1) a G protein-coupled receptor expressed on
the platelet surface leads to receptor activation
and increased intracellular Ca2thorn cyclic adenosine
monophosphate (cAMP) levels subsequently decrease
which leads to increased platelet aggregation and
releaseof further activatingfactors Vorapaxar inhibits
PAR-1 thereby signi1047297cantly reducing thrombin-
mediated platelet activation
T he T RA 2P-TIMI 50 trial (Thrombin Receptor
Antagonist for Secondary PreventionndashThrombolysis
in Myocardial Infarction Study Group) studied vor-
apaxar sulfate 25 mg daily versus placebo (ASA and
or clopidogrel therapy at the investigatorsrsquo discre-
tion) among 26449 patients with a recent myocardial
infarction recent ischemic stroke or symptomatic
PAD At 3 years there was a signi1047297cant reduction in
the primary endpoint of MACE (absolute event rates
93 vs 105 HR 087 95 CI 080 to 094
p lt 0001) (79) After 2 years the data and safety
monitoring board recommended stopping the study
drug in the patient subgroup entered with prior
ischemic stroke because of an increased risk of
intracranial hemorrhage Among the 3787 patients
with PAD the majority were treated with aspirin
monotherapy plus vorapaxar or placebo The reduc-
tion in MACE was not statistically signi1047297cant in those
assigned to vorapaxar (absolute event rates 113 vs
119 HR 094 95 CI 078 to 114) Similarly
negative results were observed among patients with
PAD who were enrolled in the TRACER (Thrombin
Receptor Antagonist for Clinical Event Reduction in
Acute Coronary Syndrome) trial (86) Additionally
vorapaxar is associated with a signi1047297cantly increased
risk of major bleeding However in both of these
trials there were relatively few MACE in the PAD
subgroup The PAD group was underpowered to draw
any conclusions on ef 1047297cacy
Pre-speci1047297ed analysis of limb-related outcomes in
the TRA 2P-TIMI 50 trial demonstrated that patients
assigned to vorapaxar had signi1047297cantly reduced rates

to fully understand these effects

there has been much interest in the use of stem cellndash
derived endothelial cells or modi1047297cation of resident
stem cells (89) Potential bene1047297ts of these therapies
include improved wound healing and limb salvage
among patients with CLI as well as improved clau-
dication distance To date numerous cell-based and
angiogenic therapies have been tested and despite
promising results in early clinical trials none of these
agents have shown bene1047297t in larger trials
ONGOING CLINICAL TRIALS
There are currently 2 clinical trials studying novel
antiplatelet and anticoagulant agents to reduce MACE
and potentially modify limb-related outcomes
EUCLID (Study Comparing Cardiovascular Effects of
Ticagrelor and Clopidogrel in Patients With Periph-eral Artery Disease) is a randomized blinded double-
dummy trial comparing ticagrelor 90 mg twice daily
to clopidogrel monotherapy among 13500 patients
with PAD (90) All patients are tested for clopidogrel
resistance before randomization The primary
endpoint is a composite of MACE and results are
expected in late 2016 The COMPASS (Rivaroxaban for
the Prevention of Major Cardiovascular Events in
Coronary or Peripheral Artery Disease) trial is evalu-
ating low-dose rivaroxaban alone versus placebo
aspirin alone or rivaroxaban and aspirin among
21400 patients with a history of myocardial infarc-tion or PAD the primary endpoint of this trial is a
composite of MACE (91)
ENDOVASCULAR THERAPY
Endovascular revascularization plays a key role in the
management of patients with PAD Patients with sta-
ble cl audication have a low ris k of lim b loss but may be
severely limited by their symptoms In most circum-
stances patients with claudication should be offered a
trial of cilostazol and an exercise program as initial
therapy If the patient is not satis1047297ed after a trial of
medical therapy endovascular revascularization can be consi dere d Patie nts with CLI require more urgent
revascularization because of an increased riskof tissue
loss and amputation as well as an extremely high risk
of cardiovascular events (92)
There are 2 well-established classi1047297cation schemes
to describe the severity of PAD The 1047297rst is a func-
tional assessment (Fontaine or Rutherford classi1047297ca-
tion [RC]) (Table 2) and the second is an anatomic
lesion classi1047297cation (Trans-Atlantic Inter-Society
Consensus [TASC]) (Table 3) (45) In addition there
has been recent interest in the angiosome concept in
helping to in1047298uence optimal revascularization stra-tegies for limb salvage (93) An angiosome is an
anatomic unit of tissue (consisting of skin subcu-
taneous tissue fascia muscle and bone) that is fed
by a source arte ry and drai ned by speci1047297c veins
If the patient is a candidate for either endovascular
or open surgery the less invasive option (ie an
endovascular-1047297rst strategy) is the current standard of
care The selection of a complex lesion (TASC D) for
endovascular therapy will vary with the skill and
experience of the interventionalist The goal in
treating a patient who has functional impairment
because of claudi cation is dura ble relief of symptoms
In patients with CLI and a threatened limb or tissueloss the goal is rapid reperfusion of the ischemic

AORTOILIAC OCCLUSIVE DISEASE
There has been a practice shift over the past 25 years
as the treatment of aortoiliac disease transitioned
from open surgery with aortobiiliac or aortobifemoral
bypass to endovascular trea tment s for comple x and
diffuse disease (TASC D) This preference for less
invasive therapy is evidence based and driven by
shorter length of stay (or treatment as an outpatient
entirely) and lower periprocedural morbidity and
mortality rates while achieving comparable patency
rates (4- to 5-year primary patency of 60 to 86
with secondary patency rates of 80 to 98) (94)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) In 2011 the European Society of Car-
diology (ESC) (3) and ACCAHA PAD guidelines (2)
recommended an endovascular-1047297rst approach for
aortoiliac lesions recommended that borderline
lesions be assessed with hemodynamic gradients and
supported primary stent placement in the aortoiliac
arteries (Table 4) The current expert consensus
document from the Society for Cardiac Angiography
and Interventions (SCAI) on appropriate use criteria
(AUC) for aortoiliac intervention are similar to the
current guidelines (95)

Treatment of TASC A B C and D Iliac Lesions) re-
ported 100 technical success in 325 patients with
aortoiliac lesions with a 24-month primary patency
rate of 879 (96) Neither TASC category nor lesion
length was predictive of restenosis These data
further support the endovascular-1047297rst strategy
regardless of TASC classi1047297cation and take into
consideration the evolution of devices (ie re-entry
catheters crossing devices and stents) which
improve success rates for the most complex lesions
COMMON FEMORAL DISEASE
Patients with common femoral artery (CFA) disease
are particularly symptomatic because the obstruction
not only occurs proximal to the super1047297cial femoral
artery (SFA) but also proximal to the deep femoralartery (profunda femoris) which is the major collat-
eral artery supplying blood to the lower limb when
there is SFA obstruction Traditionally common
femoral endarterectomy has been the CFA revascu-
larization procedure of choice (23) although
advances in endovascular therapy have shown some
promising results (97) A review of the National Sur-
gical Quality Improvement Program database for 2005
to 2010 found a combined mortality and morbidity
rate of 15 for common femoral endarterectomy
which was higher than expected (98) Patients
requiring CFA revascularization who are at increasedsurgical risk may be considered for less invasive
endovascular options
FEMORAL-POPLITEAL DISEASE
This segment begins at the bifurcation of the CFA into
the SFA and the deep femoral (profunda femoris)
artery The SFA is subject to 1047298exion elongation
compression and torsion unlike any other lower-
extremity artery This complexity leads to many
challenges for endovascular technology but despite
this an endovascular-1047297rst approach is currently thestandard of therapy for the majority of lesions
becau se of the very high proce dural success rate and
low risk (3) Some of the most lengthy and complex
lesions (TASC D) are more approachable because of
the re-entry and crossing devices more experienced
operators drug-eluting stents (DES) (99100) and
drug-coated balloons (DCBs) (101ndash107) that promise
improved long-term patency for patients with clau-
dication (99100103105)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines and the AUC documentfrom the SCAI recommend revascularization in
femoral-popliteal lesions for patients with CLI or for
patients with claudication who have had a suboptimal
r espon se to a tr ial of e xer cise (Tab le 5) An
endovascular-1047297rst approach is recommended for
TASC A through C lesions and is a reasonable option
for TASC D lesions depending on the experience of
the operator the patientrsquos comorbidities and proce-
dure safety (Table 5) (2395)
The 2 guidelines are in con1047298ict over the use of
primary stent placement in the femoral-popliteal ar-
teries with the ACCAHA guideline giving it a Class III
recommendation (do not do) and the ESC guideline
making primary femoral stenting reasonable 1047297rst-line
therapy (Class IIa) for intermediate-length lesions
(108109) The current evidence from several ran-
domized controlled trials supports primary stenting
in intermediate-length femoral stenoses and occlu-
sions (108ndash110) The soon-to-be-published updatedACCAHA guidelines will readdress this issue In
current practice the standard is to primarily stent
intermediate to long SFA lesions
The ACCAHA guideline broadly lump stents
togetherwith atherectomy devicescryotherapy laser
and cutting balloons stating they may be useful as
salvage therapy (Class IIa) but also stating that their
effectiveness remains to proven (Class IIb) Stents
should be removed from this group because their
effectiveness has been established in intermediate-
length femoral lesions Other than the use of the cut-
ting balloon and rotational atherectomy in lesions thatare resistant to dilation there is no comparative

evidence suggesting that the more expensive athe-
rectomy devices cryoplasty or laser angioplasty
should be preferred over conventional therapy
(percutaneous transluminal angioplasty [PTA] and
bare- metal stents [BMS] ) The ESC guideline disti n-
guishes bare-metal self-expanding stents from
adjunctive devices such as atherectomy devices cit-
i ng the p roven bene1047297t of BMS over PTA in
intermediate-length femoral-popliteal lesions
CLINICAL TRIAL UPDATE Three randomized controlledtrials of self-expanding BMS compared with PTA have
shown that the advantage for primary stenting is
related to lesion length For relatively discrete lesions
(mean 45 mm) (110) there was no advantage for pri-
mary stent placement however 2 other trials
(108109) with longer lesions (gt70 mm) showed a
signi1047297cant patency and functional bene1047297t for primary
femoral-popliteal BMS (Figure 3 Table 6) The proce-
dural success rate of endovascular therapy in
femoral-popliteal lesions is very high but in stable
limb ischemia durable patency remains a barrier
Cilostazol has been shown to reduce 1-year restenosis by more than one-half (20 vs 49 p frac14 00001) in
intermediate-length (128 mm) femoral lesions treated
with self-expanding BMS (114) These results need to
be con1047297rmed before this can be recommended as
standard therapy
Recent randomized controlled trials demonstrating
bene1047297t f or DE S (99100) DC B (103105106) and
covered stents (115ndash117) in femoral-popliteal arteries
will likely result in a change in the guidelines and
indications (Table 6 Figure 3)
There hasbeen some enthusiasm for self-expanding
covered (expanded polytetra1047298uoroethylene) stent
grafts in complex or lengthy femoral-popliteal seg-
ments Two randomized trials comparing covered
stents to BMS had divergent results One showed a
bene1047297t for 2-year primary patency but no difference in
target-lesion revascularization (TLR) or clinical out-
comes (116) whereas the other in longer (gt8 cm) le-
sions found no difference for primary patency (115ndash
117) When covered stents were compared with
above-the-knee femoral bypass with synthetic graft
material in a broad range of SFA lesion types (TASC A
thru D) no difference was found in the 4-year primary
patency between the 2 options (118)
The Zilver paclitaxel-eluting self-expanding DES
was superior to PTA in a randomized femoral-
popliteal trial with 1-year patency rates of 831 for
primary DES and 328 for PTA (p lt 0001) (Figure 3
Table 6) (99) There was also a 1-year patency
advantage for provisional DES after failed PTA
(899) compared with provisional BMS (730
p frac14 001) The bene1047297t was sustained at 2 years with
primary patency for the DES (748) signi1047297cantly
better t han PTA (265 p lt 001) (100) To date there
has been no head-to-head comparison of primary DES
to either BMS or DCB in femoral-popliteal arteries
but Zelle r et al (104) published a propensity scorendash
based compar ison of DES and DCB in conse cutive
patients with TASC C and D long (gt10 cm) lesions and
found no signi1047297cant differences in 1-year patency
(Figure 3 Table 6)
DCBs offer the promise of improved patency with areduced need for stents This is particularly important
in the dynamic environment of the super1047297cial femoral
and popliteal arteries where mechanical fatigue may
lead to stent fracture and increased risk of in-stent
restenosis Each DCB is unique with respect to the
paclitaxel dose (varying from 2 to 35 mgmm2) the
carrier molecule (excipient) the balloon material and
the coating technology used Superiority for paclitaxel
DCB over PTA was 1047297rst reported in 2008 (101102)
(Figure 3 Table 6) Subsequently new DCBs have
emerged including the INPACT (105106111113) and
the Lutonix (103106) balloons both of which showedclinical superiority to PTA in femoral-popliteal lesions

fewer repeat interventions Five-year follow-up

TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

Primary stent placement is not recommendedin the femoral popliteal or tibial arteries(Class III Level of Evidence C)
Surgical and endovascular intervention is notindicated in patients with severedecrements in limb perfusion (egABI lt04) in the absence of clinicalsymptoms of CLI (Class III Level of

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

reducing variation Accreditation for Cardiovascular
Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous
improvement Payers and regulators should require
or reward independent accreditation to support
value-based health care
CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

VAPOR (Vascular Physician Offer and Report) trial is
currently evaluating methods to improve physician-
patient interactions to encourage patients with PAD
to abstain from smoking (62)
PHARMACOTHERAPY TO IMPROVE
CLAUDICATION SYMPTOMS
Cilostazol is a type III phosphodiesterase inhibitorwith a number of properties but the mechanism by
which cilostazol improves claudication is not known
(63) A pooled analysis of all of the randomized
trials shows an improvement in absolute claudica-
tion distance of approximately 50 compared with
placebo (64) Although cilostazol appears to be safe
for long-term administration adherence is low (gt60
discontinuation at 3 years) because of adverse effects
including headache palpitations and diarrhea (65)
Because of its mechanistic similarity to other type III
phosphodiesterase inhibitors such as milrinone cil-
ostazol is contraindicated in patients with a history of
heart failure The optimal dose of cilostazol is 100 mg
twice daily and it may take up to 4 months to derive
maximum bene1047297t from this drug (63)
Pentoxifylline is rarely used today to treat claudi-
cation because of a lack of ef 1047297cacy compared with
cilostazol Naftidrofuryl is a 5-HT2 antagonist that is
approved in Europe In a pooled analysis involving
888 patients randomized to naftidrofuryl there was a
26 increase in pain-free walking compared with
placebo (66) It is not available for use in the United
States
ACEIs
ACEIs are associated with a signi1047297cant reduction in
MACE among patients with PAD These data are
derived primarily from the HOPE (Heart Outcomes
Prevention Evaluation) trial which randomized 9297
high-risk patients with vascular disease or diabetes
plus 1 other risk factor to ramipril 10 mg daily
or placebo Among these 1966 patients with PAD
(423) were randomized to ramipril and 2085
(448) to placebo The primary outcome (myocardial
infarction stroke cardiovascular death) occurred in
143 of those without PAD versus 220 of those
with PAD (67) In the 5231 patients without PAD the
primary outcome was observed in 126 in the ram-
ipril group and 149 in the placebo arm In those with
an ABI lt06the primary outcome occurred in 164 in
the ramipril arm versus 22 in the placebo arm Thecardiovascular bene1047297t of ramipril applies to patients
with both asymptomatic and symptomatic PAD across
a broad range of ABI values (68) Similar results have
also been observed with telmisartan which suggests a
possible class effect of ACEIangiotensin receptor
blockade among patients with PAD (6970)
STATINS
High-intensity statin medications are recommended
for a ll pa ti ents with PAD on the basis of the
most recent American College of Cardiology (ACC)American Heart Association (AHA) guidelines which

emphasize cardiovascular risk over low-density lipo-
protein targets (71) The majority of the data in sup-
port of statin use in patients with PAD are derived
from subset analysis of larger clinical trials The
Medical Research CouncilBritish Heart Foundationrsquos
Heart Protection Study randomized 20536 high-risk
patients to simvastatin 40 mg daily or placebo (72)
All-cause mortality occurred in 129 of patients
randomized to simvastatin and 147 randomized to
placebo (22 relative risk reduction p frac14 00003)
Observational studies have also con1047297rmed the car-
diovascular and overall mortality bene1047297t of statins
among patients with more advanced PAD including
CLI (73)
Recent data suggest that statin use is also associ-
ated with a reduction in adverse limb outcomes
including amputation In the REACH (Reduction of
Atherothrombosis for Continued Health) registry
statin therapy was associated with a signi1047297cant
reduction in the combined endpoint of worsening
claudication new CLI new revascularization or
amputation (74) The absolute 4-year event rates were
220 versus 262 which emphasizes the highrate of
adverse limb events among patients with symptom-
atic PAD Importantly statin therapy was also associ-
ated with a signi1047297cant reduction in 4-year rates of
ischemic amputation (38 vs 56) In an analysis of
Medicare claims data of patients undergoing lower-
extremity revascularization statin use was associ-
ated with lower rates of amputation at 30 days
90 days and 1 year (75) Single-center observational
data among patients with CLI suggest that statin
therapy is also associated with improved 1-year rates
of primary patency secondary patency and improved
limb salvage after endovascular intervention (73)
Patients with PAD should be prescribed a high-
intensity statin to reduce the risk of cardiovascular
events In most studies the rates of statin prescrip-
tion were lt75 which emphasizes the importance of
maximizing medical therapy among this high-risk
group of patients with advanced atheroscleroticdisease (59)
ANTIPLATELET THERAPY
ASPIRIN Aspirin has been a mainstay of drug ther-
apy among patients with PAD however the data
supporting aspirin use in patients with PAD have not
been well subst antia ted (7677)
Recent studies investigating the bene1047297t of aspirin
among patients with asymptomatic PAD have yielded
negative results Both the POPADAD (Prevention of
Progression of Arterial Disease and Diabetes) trial and
the AAA (Aspirin for Asymptomatic Atherosclerosis)
trial compared low-dose aspirin with placebo in
patients with a low ABI Neither study demonstrated
a reduction in fatal and nonfatal cardiovascular
events or revascularization with aspirin mono-
therapy although both notably included low-risk
patients with borderline ABI (099 in POPADAD
and 095 in AAA) (7778)
Consistent with these results a meta-analysis
speci1047297cally examined aspirin for PAD in 18 trials
involving 5269 patients In patients taking aspirin
monotherapy there was a nonsigni1047297cant reduction
in cardiovascular events (absolute event rate 82
vs 96 relative risk 075 95 con1047297dence inter-
val [CI] 048 to 118) however there was a sig-
ni1047297cant reduction in nonfatal stroke (HR 064 95
CI 042 to 099 p frac14 004) (76) In the last iteration
of the PAD guidelines (2) aspirin was a Class I
Level of Evidence A recommendation among pa-
tients with symptomatic PAD a Class IIa recom-
mendation among patients with asymptomatic PAD

CLOPIDOGREL AND
DUAL-ANTIPLATELET THERAPY
Clopidogrel is indicated as an alternative to aspirin
for antiplatelet monotherapy among patients with
PAD although recent studies suggest that lt20 of
patients with PAD are prescribed clopidogrel in clin-
ical practice (79) The data supporting clopidogrel use
are primarily based on the CAPRIE (Clopidogrel
Versus Aspirin in Patients at Risk of Ischaemic
Events) study in which clopidogrel monotherapy was
associated with a small bene1047297t compared with aspirin
325 mg daily in the overall population but there was a
238 relative risk reduction among the subgroup of
patients with symptomatic PAD (n frac14 6452 absolute
event rate 37 vs 49 per year) (80)
Dual-antiplatelet therapy (DAPT) with low-dose
aspirin (75 to 162 mg daily) and clopidogrel 75 mg
daily was studied in the CHARISMA (Clopidogrel for
High Atherothrombotic Risk and Ischemic Stabiliza-
tion Management and Avoidance) trial which
included patients at high risk for atherothrombotic
events The overall results of this trial were not sig-
ni1047297cant although in subgroup analyses there was a
bene1047297t of DAPT among patients with symptomatic
atherothrombosis (81) In an analysis of the 3096 pa-
tients in the trial with PAD DAPT was associated with
a lower rate of myocardial infarction (23 vs 37

composite primary endpoint (82) There was no dif-
ference between the groups in moderate severe or
fatal bleeding but there was an increase in minor
bleed ing i n th e DAPT group
In a recent propensity-matched observational
study among patients undergoing endovascular
intervention there was a signi1047297cant reduction in
MACE among patients taking DAPT (adjusted HR
065 95 CI 044 to 096 p frac14 003) compared with
those taking aspirin monotherapy (83) The discor-
dant 1047297ndings between this study and the CHARISMA
trial may be explained by inclusion of a cohort
with more advanced atherosclerotic disease under-
going endovascular intervention including gt50 of
patients with CLI
The CASPAR (Clopidogrel and Acetylsalicylic Acid
in Bypass Surgery for Peripheral Arterial Disease) trial
studied DAPT versus aspirin 75 to 100 mg daily among
patients undergoing below-knee surgical bypass for
treatment of CLI (84) The primary endpoint of death
major amputation index-graft occlusion or revascu-
larization was not different for DAPT versus
acetylsalicylic acid (ASA) monotherapy In a pre-
speci1047297ed subgroup analysis there was a signi1047297cant
bene1047297t of DAPT in patients treated with prosthetic
grafts (HR 065 95 CI 045 to 095 p frac14 0025) but
not in those treated with vein grafts A similar trial
the CAMPER study (Clopidogrel and Aspirin in the
Management of peripheral Endovascular Revascular-
ization) tested DAPT versus aspirin in patients un-
dergoing infrainguinal endovascular therapy The
study was never completed because of poor enroll-
ment (doctors would not randomize patients to ASA
alone) continued funding could not be justi1047297ed
DAPT is often prescribed after endovascular inter-
vention although the data supporting duration of
DAPTare sparseIn practice most physicians prescribe
DAPTfor a time periodrangingfrom1 to3 monthspost-intervention The ASPIRE-PAD study (Antiplatelet
Strategy for Peripheral Arterial Interventions for
Revascularization of Lower Extremities) is currently
evaluating comparative outcomes of 1 versus 12
months of DAPT after endovascular intervention (85)
VORAPAXAR
Thrombin acts through platelets via a unique mecha-
nism binding of the protease activating receptor-1
(PAR-1) a G protein-coupled receptor expressed on
the platelet surface leads to receptor activation
and increased intracellular Ca2thorn cyclic adenosine
monophosphate (cAMP) levels subsequently decrease
which leads to increased platelet aggregation and
releaseof further activatingfactors Vorapaxar inhibits
PAR-1 thereby signi1047297cantly reducing thrombin-
mediated platelet activation
T he T RA 2P-TIMI 50 trial (Thrombin Receptor
Antagonist for Secondary PreventionndashThrombolysis
in Myocardial Infarction Study Group) studied vor-
apaxar sulfate 25 mg daily versus placebo (ASA and
or clopidogrel therapy at the investigatorsrsquo discre-
tion) among 26449 patients with a recent myocardial
infarction recent ischemic stroke or symptomatic
PAD At 3 years there was a signi1047297cant reduction in
the primary endpoint of MACE (absolute event rates
93 vs 105 HR 087 95 CI 080 to 094
p lt 0001) (79) After 2 years the data and safety
monitoring board recommended stopping the study
drug in the patient subgroup entered with prior
ischemic stroke because of an increased risk of
intracranial hemorrhage Among the 3787 patients
with PAD the majority were treated with aspirin
monotherapy plus vorapaxar or placebo The reduc-
tion in MACE was not statistically signi1047297cant in those
assigned to vorapaxar (absolute event rates 113 vs
119 HR 094 95 CI 078 to 114) Similarly
negative results were observed among patients with
PAD who were enrolled in the TRACER (Thrombin
Receptor Antagonist for Clinical Event Reduction in
Acute Coronary Syndrome) trial (86) Additionally
vorapaxar is associated with a signi1047297cantly increased
risk of major bleeding However in both of these
trials there were relatively few MACE in the PAD
subgroup The PAD group was underpowered to draw
any conclusions on ef 1047297cacy
Pre-speci1047297ed analysis of limb-related outcomes in
the TRA 2P-TIMI 50 trial demonstrated that patients
assigned to vorapaxar had signi1047297cantly reduced rates
of acute limb ischemia (23 vs 39 HR 058 95
CI 039 to 086 p frac14 0006) as well as peripheral
artery revascularization (184 vs 222 HR 084
95 CI 073 to 097 p frac14 0017) during the 3-yearfollow-up (Figure 2) (87) These ef 1047297cacy endpoints
must be balanced by a signi1047297cantly increased rate of
major bleeding among patients prescribed vorapaxar
Further research into the mechanism by which
vorapaxar led to improved limb outcomes is required
to fully understand these effects
CELL-BASED AND ANGIOGENIC THERAPIES
Modulation and enhancement of lower-extremity
blood 1047298ow via angiogenesis arteriogenesis or vas-
culogenesis could provide a promising breakthrough
therapy for patients with PAD (88) Additionally

there has been much interest in the use of stem cellndash
derived endothelial cells or modi1047297cation of resident
stem cells (89) Potential bene1047297ts of these therapies
include improved wound healing and limb salvage
among patients with CLI as well as improved clau-
dication distance To date numerous cell-based and
angiogenic therapies have been tested and despite
promising results in early clinical trials none of these
agents have shown bene1047297t in larger trials
ONGOING CLINICAL TRIALS
There are currently 2 clinical trials studying novel
antiplatelet and anticoagulant agents to reduce MACE
and potentially modify limb-related outcomes
EUCLID (Study Comparing Cardiovascular Effects of
Ticagrelor and Clopidogrel in Patients With Periph-eral Artery Disease) is a randomized blinded double-
dummy trial comparing ticagrelor 90 mg twice daily
to clopidogrel monotherapy among 13500 patients
with PAD (90) All patients are tested for clopidogrel
resistance before randomization The primary
endpoint is a composite of MACE and results are
expected in late 2016 The COMPASS (Rivaroxaban for
the Prevention of Major Cardiovascular Events in
Coronary or Peripheral Artery Disease) trial is evalu-
ating low-dose rivaroxaban alone versus placebo
aspirin alone or rivaroxaban and aspirin among
21400 patients with a history of myocardial infarc-tion or PAD the primary endpoint of this trial is a
composite of MACE (91)
ENDOVASCULAR THERAPY
Endovascular revascularization plays a key role in the
management of patients with PAD Patients with sta-
ble cl audication have a low ris k of lim b loss but may be
severely limited by their symptoms In most circum-
stances patients with claudication should be offered a
trial of cilostazol and an exercise program as initial
therapy If the patient is not satis1047297ed after a trial of
medical therapy endovascular revascularization can be consi dere d Patie nts with CLI require more urgent
revascularization because of an increased riskof tissue
loss and amputation as well as an extremely high risk
of cardiovascular events (92)
There are 2 well-established classi1047297cation schemes
to describe the severity of PAD The 1047297rst is a func-
tional assessment (Fontaine or Rutherford classi1047297ca-
tion [RC]) (Table 2) and the second is an anatomic
lesion classi1047297cation (Trans-Atlantic Inter-Society
Consensus [TASC]) (Table 3) (45) In addition there
has been recent interest in the angiosome concept in
helping to in1047298uence optimal revascularization stra-tegies for limb salvage (93) An angiosome is an
anatomic unit of tissue (consisting of skin subcu-
taneous tissue fascia muscle and bone) that is fed
by a source arte ry and drai ned by speci1047297c veins
If the patient is a candidate for either endovascular
or open surgery the less invasive option (ie an
endovascular-1047297rst strategy) is the current standard of
care The selection of a complex lesion (TASC D) for
endovascular therapy will vary with the skill and
experience of the interventionalist The goal in
treating a patient who has functional impairment
because of claudi cation is dura ble relief of symptoms
In patients with CLI and a threatened limb or tissueloss the goal is rapid reperfusion of the ischemic

AORTOILIAC OCCLUSIVE DISEASE
There has been a practice shift over the past 25 years
as the treatment of aortoiliac disease transitioned
from open surgery with aortobiiliac or aortobifemoral
bypass to endovascular trea tment s for comple x and
diffuse disease (TASC D) This preference for less
invasive therapy is evidence based and driven by
shorter length of stay (or treatment as an outpatient
entirely) and lower periprocedural morbidity and
mortality rates while achieving comparable patency
rates (4- to 5-year primary patency of 60 to 86
with secondary patency rates of 80 to 98) (94)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) In 2011 the European Society of Car-
diology (ESC) (3) and ACCAHA PAD guidelines (2)
recommended an endovascular-1047297rst approach for
aortoiliac lesions recommended that borderline
lesions be assessed with hemodynamic gradients and
supported primary stent placement in the aortoiliac
arteries (Table 4) The current expert consensus
document from the Society for Cardiac Angiography
and Interventions (SCAI) on appropriate use criteria
(AUC) for aortoiliac intervention are similar to the
current guidelines (95)

Treatment of TASC A B C and D Iliac Lesions) re-
ported 100 technical success in 325 patients with
aortoiliac lesions with a 24-month primary patency
rate of 879 (96) Neither TASC category nor lesion
length was predictive of restenosis These data
further support the endovascular-1047297rst strategy
regardless of TASC classi1047297cation and take into
consideration the evolution of devices (ie re-entry
catheters crossing devices and stents) which
improve success rates for the most complex lesions
COMMON FEMORAL DISEASE
Patients with common femoral artery (CFA) disease
are particularly symptomatic because the obstruction
not only occurs proximal to the super1047297cial femoral
artery (SFA) but also proximal to the deep femoralartery (profunda femoris) which is the major collat-
eral artery supplying blood to the lower limb when
there is SFA obstruction Traditionally common
femoral endarterectomy has been the CFA revascu-
larization procedure of choice (23) although
advances in endovascular therapy have shown some
promising results (97) A review of the National Sur-
gical Quality Improvement Program database for 2005
to 2010 found a combined mortality and morbidity
rate of 15 for common femoral endarterectomy
which was higher than expected (98) Patients
requiring CFA revascularization who are at increasedsurgical risk may be considered for less invasive
endovascular options
FEMORAL-POPLITEAL DISEASE
This segment begins at the bifurcation of the CFA into
the SFA and the deep femoral (profunda femoris)
artery The SFA is subject to 1047298exion elongation
compression and torsion unlike any other lower-
extremity artery This complexity leads to many
challenges for endovascular technology but despite
this an endovascular-1047297rst approach is currently thestandard of therapy for the majority of lesions
becau se of the very high proce dural success rate and
low risk (3) Some of the most lengthy and complex
lesions (TASC D) are more approachable because of
the re-entry and crossing devices more experienced
operators drug-eluting stents (DES) (99100) and
drug-coated balloons (DCBs) (101ndash107) that promise
improved long-term patency for patients with clau-
dication (99100103105)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines and the AUC documentfrom the SCAI recommend revascularization in
femoral-popliteal lesions for patients with CLI or for
patients with claudication who have had a suboptimal
r espon se to a tr ial of e xer cise (Tab le 5) An
endovascular-1047297rst approach is recommended for
TASC A through C lesions and is a reasonable option
for TASC D lesions depending on the experience of
the operator the patientrsquos comorbidities and proce-
dure safety (Table 5) (2395)
The 2 guidelines are in con1047298ict over the use of
primary stent placement in the femoral-popliteal ar-
teries with the ACCAHA guideline giving it a Class III
recommendation (do not do) and the ESC guideline
making primary femoral stenting reasonable 1047297rst-line
therapy (Class IIa) for intermediate-length lesions
(108109) The current evidence from several ran-
domized controlled trials supports primary stenting
in intermediate-length femoral stenoses and occlu-
sions (108ndash110) The soon-to-be-published updatedACCAHA guidelines will readdress this issue In
current practice the standard is to primarily stent
intermediate to long SFA lesions
The ACCAHA guideline broadly lump stents
togetherwith atherectomy devicescryotherapy laser
and cutting balloons stating they may be useful as
salvage therapy (Class IIa) but also stating that their
effectiveness remains to proven (Class IIb) Stents
should be removed from this group because their
effectiveness has been established in intermediate-
length femoral lesions Other than the use of the cut-
ting balloon and rotational atherectomy in lesions thatare resistant to dilation there is no comparative

evidence suggesting that the more expensive athe-
rectomy devices cryoplasty or laser angioplasty
should be preferred over conventional therapy
(percutaneous transluminal angioplasty [PTA] and
bare- metal stents [BMS] ) The ESC guideline disti n-
guishes bare-metal self-expanding stents from
adjunctive devices such as atherectomy devices cit-
i ng the p roven bene1047297t of BMS over PTA in
intermediate-length femoral-popliteal lesions
CLINICAL TRIAL UPDATE Three randomized controlledtrials of self-expanding BMS compared with PTA have
shown that the advantage for primary stenting is
related to lesion length For relatively discrete lesions
(mean 45 mm) (110) there was no advantage for pri-
mary stent placement however 2 other trials
(108109) with longer lesions (gt70 mm) showed a
signi1047297cant patency and functional bene1047297t for primary
femoral-popliteal BMS (Figure 3 Table 6) The proce-
dural success rate of endovascular therapy in
femoral-popliteal lesions is very high but in stable
limb ischemia durable patency remains a barrier
Cilostazol has been shown to reduce 1-year restenosis by more than one-half (20 vs 49 p frac14 00001) in
intermediate-length (128 mm) femoral lesions treated
with self-expanding BMS (114) These results need to
be con1047297rmed before this can be recommended as
standard therapy
Recent randomized controlled trials demonstrating
bene1047297t f or DE S (99100) DC B (103105106) and
covered stents (115ndash117) in femoral-popliteal arteries
will likely result in a change in the guidelines and
indications (Table 6 Figure 3)
There hasbeen some enthusiasm for self-expanding
covered (expanded polytetra1047298uoroethylene) stent
grafts in complex or lengthy femoral-popliteal seg-
ments Two randomized trials comparing covered
stents to BMS had divergent results One showed a
bene1047297t for 2-year primary patency but no difference in
target-lesion revascularization (TLR) or clinical out-
comes (116) whereas the other in longer (gt8 cm) le-
sions found no difference for primary patency (115ndash
117) When covered stents were compared with
above-the-knee femoral bypass with synthetic graft
material in a broad range of SFA lesion types (TASC A
thru D) no difference was found in the 4-year primary
patency between the 2 options (118)
The Zilver paclitaxel-eluting self-expanding DES
was superior to PTA in a randomized femoral-
popliteal trial with 1-year patency rates of 831 for
primary DES and 328 for PTA (p lt 0001) (Figure 3
Table 6) (99) There was also a 1-year patency
advantage for provisional DES after failed PTA
(899) compared with provisional BMS (730
p frac14 001) The bene1047297t was sustained at 2 years with
primary patency for the DES (748) signi1047297cantly
better t han PTA (265 p lt 001) (100) To date there
has been no head-to-head comparison of primary DES
to either BMS or DCB in femoral-popliteal arteries
but Zelle r et al (104) published a propensity scorendash
based compar ison of DES and DCB in conse cutive
patients with TASC C and D long (gt10 cm) lesions and
found no signi1047297cant differences in 1-year patency
(Figure 3 Table 6)
DCBs offer the promise of improved patency with areduced need for stents This is particularly important
in the dynamic environment of the super1047297cial femoral
and popliteal arteries where mechanical fatigue may
lead to stent fracture and increased risk of in-stent
restenosis Each DCB is unique with respect to the
paclitaxel dose (varying from 2 to 35 mgmm2) the
carrier molecule (excipient) the balloon material and
the coating technology used Superiority for paclitaxel
DCB over PTA was 1047297rst reported in 2008 (101102)
(Figure 3 Table 6) Subsequently new DCBs have
emerged including the INPACT (105106111113) and
the Lutonix (103106) balloons both of which showedclinical superiority to PTA in femoral-popliteal lesions

TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

reducing variation Accreditation for Cardiovascular
Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous
improvement Payers and regulators should require
or reward independent accreditation to support
value-based health care
CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

emphasize cardiovascular risk over low-density lipo-
protein targets (71) The majority of the data in sup-
port of statin use in patients with PAD are derived
from subset analysis of larger clinical trials The
Medical Research CouncilBritish Heart Foundationrsquos
Heart Protection Study randomized 20536 high-risk
patients to simvastatin 40 mg daily or placebo (72)
All-cause mortality occurred in 129 of patients
randomized to simvastatin and 147 randomized to
placebo (22 relative risk reduction p frac14 00003)
Observational studies have also con1047297rmed the car-
diovascular and overall mortality bene1047297t of statins
among patients with more advanced PAD including
CLI (73)
Recent data suggest that statin use is also associ-
ated with a reduction in adverse limb outcomes
including amputation In the REACH (Reduction of
Atherothrombosis for Continued Health) registry
statin therapy was associated with a signi1047297cant
reduction in the combined endpoint of worsening
claudication new CLI new revascularization or
amputation (74) The absolute 4-year event rates were
220 versus 262 which emphasizes the highrate of
adverse limb events among patients with symptom-
atic PAD Importantly statin therapy was also associ-
ated with a signi1047297cant reduction in 4-year rates of
ischemic amputation (38 vs 56) In an analysis of
Medicare claims data of patients undergoing lower-
extremity revascularization statin use was associ-
ated with lower rates of amputation at 30 days
90 days and 1 year (75) Single-center observational
data among patients with CLI suggest that statin
therapy is also associated with improved 1-year rates
of primary patency secondary patency and improved
limb salvage after endovascular intervention (73)
Patients with PAD should be prescribed a high-
intensity statin to reduce the risk of cardiovascular
events In most studies the rates of statin prescrip-
tion were lt75 which emphasizes the importance of
maximizing medical therapy among this high-risk
group of patients with advanced atheroscleroticdisease (59)
ANTIPLATELET THERAPY

apy among patients with PAD however the data
supporting aspirin use in patients with PAD have not
been well subst antia ted (7677)
Recent studies investigating the bene1047297t of aspirin
among patients with asymptomatic PAD have yielded
negative results Both the POPADAD (Prevention of
Progression of Arterial Disease and Diabetes) trial and
the AAA (Aspirin for Asymptomatic Atherosclerosis)
trial compared low-dose aspirin with placebo in
patients with a low ABI Neither study demonstrated
a reduction in fatal and nonfatal cardiovascular
events or revascularization with aspirin mono-
therapy although both notably included low-risk
patients with borderline ABI (099 in POPADAD
and 095 in AAA) (7778)
Consistent with these results a meta-analysis
speci1047297cally examined aspirin for PAD in 18 trials
involving 5269 patients In patients taking aspirin
monotherapy there was a nonsigni1047297cant reduction
in cardiovascular events (absolute event rate 82
vs 96 relative risk 075 95 con1047297dence inter-
val [CI] 048 to 118) however there was a sig-
ni1047297cant reduction in nonfatal stroke (HR 064 95
CI 042 to 099 p frac14 004) (76) In the last iteration
of the PAD guidelines (2) aspirin was a Class I
Level of Evidence A recommendation among pa-
tients with symptomatic PAD a Class IIa recom-
mendation among patients with asymptomatic PAD
and an ABI lt090 and a Class IIb indication among
asymptomatic patients with an ABI of 090 to 099
(2) Some of these recommendations may change in
the upcoming revision of the ACCAHA PAD prac-
tice guidelines
CLOPIDOGREL AND
DUAL-ANTIPLATELET THERAPY
Clopidogrel is indicated as an alternative to aspirin
for antiplatelet monotherapy among patients with
PAD although recent studies suggest that lt20 of
patients with PAD are prescribed clopidogrel in clin-
ical practice (79) The data supporting clopidogrel use
are primarily based on the CAPRIE (Clopidogrel
Versus Aspirin in Patients at Risk of Ischaemic
Events) study in which clopidogrel monotherapy was
associated with a small bene1047297t compared with aspirin
325 mg daily in the overall population but there was a
238 relative risk reduction among the subgroup of
patients with symptomatic PAD (n frac14 6452 absolute
event rate 37 vs 49 per year) (80)
Dual-antiplatelet therapy (DAPT) with low-dose
aspirin (75 to 162 mg daily) and clopidogrel 75 mg
daily was studied in the CHARISMA (Clopidogrel for
High Atherothrombotic Risk and Ischemic Stabiliza-
tion Management and Avoidance) trial which
included patients at high risk for atherothrombotic
events The overall results of this trial were not sig-
ni1047297cant although in subgroup analyses there was a
bene1047297t of DAPT among patients with symptomatic
atherothrombosis (81) In an analysis of the 3096 pa-
tients in the trial with PAD DAPT was associated with
a lower rate of myocardial infarction (23 vs 37

composite primary endpoint (82) There was no dif-
ference between the groups in moderate severe or
fatal bleeding but there was an increase in minor
bleed ing i n th e DAPT group
In a recent propensity-matched observational
study among patients undergoing endovascular
intervention there was a signi1047297cant reduction in
MACE among patients taking DAPT (adjusted HR
065 95 CI 044 to 096 p frac14 003) compared with
those taking aspirin monotherapy (83) The discor-
dant 1047297ndings between this study and the CHARISMA
trial may be explained by inclusion of a cohort
with more advanced atherosclerotic disease under-
going endovascular intervention including gt50 of
patients with CLI
The CASPAR (Clopidogrel and Acetylsalicylic Acid
in Bypass Surgery for Peripheral Arterial Disease) trial
studied DAPT versus aspirin 75 to 100 mg daily among
patients undergoing below-knee surgical bypass for
treatment of CLI (84) The primary endpoint of death
major amputation index-graft occlusion or revascu-
larization was not different for DAPT versus
acetylsalicylic acid (ASA) monotherapy In a pre-
speci1047297ed subgroup analysis there was a signi1047297cant
bene1047297t of DAPT in patients treated with prosthetic
grafts (HR 065 95 CI 045 to 095 p frac14 0025) but
not in those treated with vein grafts A similar trial
the CAMPER study (Clopidogrel and Aspirin in the
Management of peripheral Endovascular Revascular-
ization) tested DAPT versus aspirin in patients un-
dergoing infrainguinal endovascular therapy The
study was never completed because of poor enroll-
ment (doctors would not randomize patients to ASA
alone) continued funding could not be justi1047297ed
DAPT is often prescribed after endovascular inter-
vention although the data supporting duration of
DAPTare sparseIn practice most physicians prescribe
DAPTfor a time periodrangingfrom1 to3 monthspost-intervention The ASPIRE-PAD study (Antiplatelet
Strategy for Peripheral Arterial Interventions for
Revascularization of Lower Extremities) is currently
evaluating comparative outcomes of 1 versus 12
months of DAPT after endovascular intervention (85)
VORAPAXAR
Thrombin acts through platelets via a unique mecha-
nism binding of the protease activating receptor-1
(PAR-1) a G protein-coupled receptor expressed on
the platelet surface leads to receptor activation
and increased intracellular Ca2thorn cyclic adenosine
monophosphate (cAMP) levels subsequently decrease
which leads to increased platelet aggregation and
releaseof further activatingfactors Vorapaxar inhibits
PAR-1 thereby signi1047297cantly reducing thrombin-
mediated platelet activation
T he T RA 2P-TIMI 50 trial (Thrombin Receptor
Antagonist for Secondary PreventionndashThrombolysis
in Myocardial Infarction Study Group) studied vor-
apaxar sulfate 25 mg daily versus placebo (ASA and
or clopidogrel therapy at the investigatorsrsquo discre-
tion) among 26449 patients with a recent myocardial
infarction recent ischemic stroke or symptomatic
PAD At 3 years there was a signi1047297cant reduction in
the primary endpoint of MACE (absolute event rates
93 vs 105 HR 087 95 CI 080 to 094
p lt 0001) (79) After 2 years the data and safety
monitoring board recommended stopping the study
drug in the patient subgroup entered with prior
ischemic stroke because of an increased risk of
intracranial hemorrhage Among the 3787 patients
with PAD the majority were treated with aspirin
monotherapy plus vorapaxar or placebo The reduc-
tion in MACE was not statistically signi1047297cant in those
assigned to vorapaxar (absolute event rates 113 vs
119 HR 094 95 CI 078 to 114) Similarly
negative results were observed among patients with
PAD who were enrolled in the TRACER (Thrombin
Receptor Antagonist for Clinical Event Reduction in
Acute Coronary Syndrome) trial (86) Additionally
vorapaxar is associated with a signi1047297cantly increased
risk of major bleeding However in both of these
trials there were relatively few MACE in the PAD
subgroup The PAD group was underpowered to draw
any conclusions on ef 1047297cacy
Pre-speci1047297ed analysis of limb-related outcomes in
the TRA 2P-TIMI 50 trial demonstrated that patients
assigned to vorapaxar had signi1047297cantly reduced rates
of acute limb ischemia (23 vs 39 HR 058 95
CI 039 to 086 p frac14 0006) as well as peripheral
artery revascularization (184 vs 222 HR 084
95 CI 073 to 097 p frac14 0017) during the 3-yearfollow-up (Figure 2) (87) These ef 1047297cacy endpoints
must be balanced by a signi1047297cantly increased rate of
major bleeding among patients prescribed vorapaxar
Further research into the mechanism by which
vorapaxar led to improved limb outcomes is required
to fully understand these effects
CELL-BASED AND ANGIOGENIC THERAPIES
Modulation and enhancement of lower-extremity
blood 1047298ow via angiogenesis arteriogenesis or vas-
culogenesis could provide a promising breakthrough
therapy for patients with PAD (88) Additionally

there has been much interest in the use of stem cellndash
derived endothelial cells or modi1047297cation of resident
stem cells (89) Potential bene1047297ts of these therapies
include improved wound healing and limb salvage
among patients with CLI as well as improved clau-
dication distance To date numerous cell-based and
angiogenic therapies have been tested and despite
promising results in early clinical trials none of these
agents have shown bene1047297t in larger trials
ONGOING CLINICAL TRIALS
There are currently 2 clinical trials studying novel
antiplatelet and anticoagulant agents to reduce MACE
and potentially modify limb-related outcomes
EUCLID (Study Comparing Cardiovascular Effects of
Ticagrelor and Clopidogrel in Patients With Periph-eral Artery Disease) is a randomized blinded double-
dummy trial comparing ticagrelor 90 mg twice daily
to clopidogrel monotherapy among 13500 patients
with PAD (90) All patients are tested for clopidogrel
resistance before randomization The primary
endpoint is a composite of MACE and results are
expected in late 2016 The COMPASS (Rivaroxaban for
the Prevention of Major Cardiovascular Events in
Coronary or Peripheral Artery Disease) trial is evalu-
ating low-dose rivaroxaban alone versus placebo
aspirin alone or rivaroxaban and aspirin among
21400 patients with a history of myocardial infarc-tion or PAD the primary endpoint of this trial is a
composite of MACE (91)
ENDOVASCULAR THERAPY
Endovascular revascularization plays a key role in the
management of patients with PAD Patients with sta-
ble cl audication have a low ris k of lim b loss but may be
severely limited by their symptoms In most circum-
stances patients with claudication should be offered a
trial of cilostazol and an exercise program as initial
therapy If the patient is not satis1047297ed after a trial of
medical therapy endovascular revascularization can be consi dere d Patie nts with CLI require more urgent
revascularization because of an increased riskof tissue
loss and amputation as well as an extremely high risk
of cardiovascular events (92)
There are 2 well-established classi1047297cation schemes
to describe the severity of PAD The 1047297rst is a func-
tional assessment (Fontaine or Rutherford classi1047297ca-
tion [RC]) (Table 2) and the second is an anatomic
lesion classi1047297cation (Trans-Atlantic Inter-Society
Consensus [TASC]) (Table 3) (45) In addition there
has been recent interest in the angiosome concept in
helping to in1047298uence optimal revascularization stra-tegies for limb salvage (93) An angiosome is an
anatomic unit of tissue (consisting of skin subcu-
taneous tissue fascia muscle and bone) that is fed
by a source arte ry and drai ned by speci1047297c veins
If the patient is a candidate for either endovascular
or open surgery the less invasive option (ie an
endovascular-1047297rst strategy) is the current standard of
care The selection of a complex lesion (TASC D) for
endovascular therapy will vary with the skill and
experience of the interventionalist The goal in
treating a patient who has functional impairment
because of claudi cation is dura ble relief of symptoms
In patients with CLI and a threatened limb or tissueloss the goal is rapid reperfusion of the ischemic

AORTOILIAC OCCLUSIVE DISEASE
There has been a practice shift over the past 25 years
as the treatment of aortoiliac disease transitioned
from open surgery with aortobiiliac or aortobifemoral
bypass to endovascular trea tment s for comple x and
diffuse disease (TASC D) This preference for less
invasive therapy is evidence based and driven by
shorter length of stay (or treatment as an outpatient
entirely) and lower periprocedural morbidity and
mortality rates while achieving comparable patency
rates (4- to 5-year primary patency of 60 to 86
with secondary patency rates of 80 to 98) (94)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) In 2011 the European Society of Car-
diology (ESC) (3) and ACCAHA PAD guidelines (2)
recommended an endovascular-1047297rst approach for
aortoiliac lesions recommended that borderline
lesions be assessed with hemodynamic gradients and
supported primary stent placement in the aortoiliac
arteries (Table 4) The current expert consensus
document from the Society for Cardiac Angiography
and Interventions (SCAI) on appropriate use criteria
(AUC) for aortoiliac intervention are similar to the
current guidelines (95)

Treatment of TASC A B C and D Iliac Lesions) re-
ported 100 technical success in 325 patients with
aortoiliac lesions with a 24-month primary patency
rate of 879 (96) Neither TASC category nor lesion
length was predictive of restenosis These data
further support the endovascular-1047297rst strategy
regardless of TASC classi1047297cation and take into
consideration the evolution of devices (ie re-entry
catheters crossing devices and stents) which
improve success rates for the most complex lesions
COMMON FEMORAL DISEASE
Patients with common femoral artery (CFA) disease
are particularly symptomatic because the obstruction
not only occurs proximal to the super1047297cial femoral
artery (SFA) but also proximal to the deep femoralartery (profunda femoris) which is the major collat-
eral artery supplying blood to the lower limb when
there is SFA obstruction Traditionally common
femoral endarterectomy has been the CFA revascu-
larization procedure of choice (23) although
advances in endovascular therapy have shown some
promising results (97) A review of the National Sur-
gical Quality Improvement Program database for 2005
to 2010 found a combined mortality and morbidity
rate of 15 for common femoral endarterectomy
which was higher than expected (98) Patients
requiring CFA revascularization who are at increasedsurgical risk may be considered for less invasive
endovascular options
FEMORAL-POPLITEAL DISEASE
This segment begins at the bifurcation of the CFA into
the SFA and the deep femoral (profunda femoris)
artery The SFA is subject to 1047298exion elongation
compression and torsion unlike any other lower-
extremity artery This complexity leads to many
challenges for endovascular technology but despite
this an endovascular-1047297rst approach is currently thestandard of therapy for the majority of lesions
becau se of the very high proce dural success rate and
low risk (3) Some of the most lengthy and complex
lesions (TASC D) are more approachable because of
the re-entry and crossing devices more experienced
operators drug-eluting stents (DES) (99100) and
drug-coated balloons (DCBs) (101ndash107) that promise
improved long-term patency for patients with clau-
dication (99100103105)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines and the AUC documentfrom the SCAI recommend revascularization in
femoral-popliteal lesions for patients with CLI or for
patients with claudication who have had a suboptimal
r espon se to a tr ial of e xer cise (Tab le 5) An
endovascular-1047297rst approach is recommended for
TASC A through C lesions and is a reasonable option
for TASC D lesions depending on the experience of
the operator the patientrsquos comorbidities and proce-
dure safety (Table 5) (2395)
The 2 guidelines are in con1047298ict over the use of
primary stent placement in the femoral-popliteal ar-
teries with the ACCAHA guideline giving it a Class III
recommendation (do not do) and the ESC guideline
making primary femoral stenting reasonable 1047297rst-line
therapy (Class IIa) for intermediate-length lesions
(108109) The current evidence from several ran-
domized controlled trials supports primary stenting
in intermediate-length femoral stenoses and occlu-
sions (108ndash110) The soon-to-be-published updatedACCAHA guidelines will readdress this issue In
current practice the standard is to primarily stent
intermediate to long SFA lesions
The ACCAHA guideline broadly lump stents
togetherwith atherectomy devicescryotherapy laser
and cutting balloons stating they may be useful as
salvage therapy (Class IIa) but also stating that their
effectiveness remains to proven (Class IIb) Stents
should be removed from this group because their
effectiveness has been established in intermediate-
length femoral lesions Other than the use of the cut-
ting balloon and rotational atherectomy in lesions thatare resistant to dilation there is no comparative

evidence suggesting that the more expensive athe-
rectomy devices cryoplasty or laser angioplasty
should be preferred over conventional therapy
(percutaneous transluminal angioplasty [PTA] and
bare- metal stents [BMS] ) The ESC guideline disti n-
guishes bare-metal self-expanding stents from
adjunctive devices such as atherectomy devices cit-
i ng the p roven bene1047297t of BMS over PTA in
intermediate-length femoral-popliteal lesions
CLINICAL TRIAL UPDATE Three randomized controlledtrials of self-expanding BMS compared with PTA have
shown that the advantage for primary stenting is
related to lesion length For relatively discrete lesions
(mean 45 mm) (110) there was no advantage for pri-
mary stent placement however 2 other trials
(108109) with longer lesions (gt70 mm) showed a
signi1047297cant patency and functional bene1047297t for primary
femoral-popliteal BMS (Figure 3 Table 6) The proce-
dural success rate of endovascular therapy in
femoral-popliteal lesions is very high but in stable
limb ischemia durable patency remains a barrier
Cilostazol has been shown to reduce 1-year restenosis by more than one-half (20 vs 49 p frac14 00001) in
intermediate-length (128 mm) femoral lesions treated
with self-expanding BMS (114) These results need to
be con1047297rmed before this can be recommended as
standard therapy
Recent randomized controlled trials demonstrating
bene1047297t f or DE S (99100) DC B (103105106) and
covered stents (115ndash117) in femoral-popliteal arteries
will likely result in a change in the guidelines and
indications (Table 6 Figure 3)
There hasbeen some enthusiasm for self-expanding
covered (expanded polytetra1047298uoroethylene) stent
grafts in complex or lengthy femoral-popliteal seg-
ments Two randomized trials comparing covered
stents to BMS had divergent results One showed a
bene1047297t for 2-year primary patency but no difference in
target-lesion revascularization (TLR) or clinical out-
comes (116) whereas the other in longer (gt8 cm) le-
sions found no difference for primary patency (115ndash
117) When covered stents were compared with
above-the-knee femoral bypass with synthetic graft
material in a broad range of SFA lesion types (TASC A
thru D) no difference was found in the 4-year primary
patency between the 2 options (118)
The Zilver paclitaxel-eluting self-expanding DES
was superior to PTA in a randomized femoral-
popliteal trial with 1-year patency rates of 831 for
primary DES and 328 for PTA (p lt 0001) (Figure 3
Table 6) (99) There was also a 1-year patency
advantage for provisional DES after failed PTA
(899) compared with provisional BMS (730
p frac14 001) The bene1047297t was sustained at 2 years with
primary patency for the DES (748) signi1047297cantly
better t han PTA (265 p lt 001) (100) To date there
has been no head-to-head comparison of primary DES
to either BMS or DCB in femoral-popliteal arteries
but Zelle r et al (104) published a propensity scorendash
based compar ison of DES and DCB in conse cutive
patients with TASC C and D long (gt10 cm) lesions and
found no signi1047297cant differences in 1-year patency
(Figure 3 Table 6)
DCBs offer the promise of improved patency with areduced need for stents This is particularly important
in the dynamic environment of the super1047297cial femoral
and popliteal arteries where mechanical fatigue may
lead to stent fracture and increased risk of in-stent
restenosis Each DCB is unique with respect to the
paclitaxel dose (varying from 2 to 35 mgmm2) the
carrier molecule (excipient) the balloon material and
the coating technology used Superiority for paclitaxel
DCB over PTA was 1047297rst reported in 2008 (101102)

Endovascular procedures are indicated for patientswith a vocational or lifestyle-limiting disabilitydue to intermittent claudication when clinicalfeatures suggest a reasonable likelihood of symptomatic improvement with endovascularintervention and 1) there has been aninadequate response to exercise orpharmacological therapy andor 2) there is avery favorable risk-bene1047297t ratio (eg focalstenosis) (Class I Level of Evidence A)
When revascularization is indicated anendovascular-1047297rst strategy isrecommended in all femoropoplitealTASC AndashC lesions (Class I Level of
Evidence C)
Stents (and other adjunctive techniques such aslasers cutting balloons atherectomy devicesand thermal devices) can be useful in thefemoral popliteal and tibial arteries as salvagetherapy for a suboptimal or failed result fromballoon dilation (eg persistent translesionalgradient residual diameter stenosis gt50 or1047298ow-limiting dissection) (Class IIa Level of
Evidence C)
Primary stent implantation should beconsidered in femoropopliteal TASCB lesions (Class IIa Level of
Evidence A)
The effectiveness of stents atherectomy cuttingballoons thermal devices and lasers for thetreatment of femoral-popliteal arterial lesions isnot well established (except to salvage asuboptimal result from balloon dilation) (Class
IIb Level of Evidence A)
A primary endovascular approach mayalso be considered in TASC D lesionsin patients with severe comorbiditiesif an experienced interventionist isavailable (Class IIb Level of
Evidence C)
Primary stent placement is not recommended in thefemoral popliteal or tibial arteries (Class III
Level of Evidence C)
Endovascular intervention is not indicated asprophylactic therapy in an asymptomatic patientwith lower-extremity PAD (Class III Level of
Evidence C)

TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

reducing variation Accreditation for Cardiovascular
Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous
improvement Payers and regulators should require
or reward independent accreditation to support
value-based health care
CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

those taking aspirin monotherapy (83) The discor-
dant 1047297ndings between this study and the CHARISMA
trial may be explained by inclusion of a cohort
with more advanced atherosclerotic disease under-
going endovascular intervention including gt50 of
patients with CLI
The CASPAR (Clopidogrel and Acetylsalicylic Acid
in Bypass Surgery for Peripheral Arterial Disease) trial
studied DAPT versus aspirin 75 to 100 mg daily among
patients undergoing below-knee surgical bypass for
treatment of CLI (84) The primary endpoint of death
major amputation index-graft occlusion or revascu-
larization was not different for DAPT versus
acetylsalicylic acid (ASA) monotherapy In a pre-
speci1047297ed subgroup analysis there was a signi1047297cant
bene1047297t of DAPT in patients treated with prosthetic
grafts (HR 065 95 CI 045 to 095 p frac14 0025) but
not in those treated with vein grafts A similar trial
the CAMPER study (Clopidogrel and Aspirin in the
Management of peripheral Endovascular Revascular-
ization) tested DAPT versus aspirin in patients un-
dergoing infrainguinal endovascular therapy The
study was never completed because of poor enroll-
ment (doctors would not randomize patients to ASA
alone) continued funding could not be justi1047297ed
DAPT is often prescribed after endovascular inter-
vention although the data supporting duration of
DAPTare sparseIn practice most physicians prescribe
DAPTfor a time periodrangingfrom1 to3 monthspost-intervention The ASPIRE-PAD study (Antiplatelet
Strategy for Peripheral Arterial Interventions for
Revascularization of Lower Extremities) is currently
evaluating comparative outcomes of 1 versus 12
months of DAPT after endovascular intervention (85)
VORAPAXAR
Thrombin acts through platelets via a unique mecha-
nism binding of the protease activating receptor-1
(PAR-1) a G protein-coupled receptor expressed on
the platelet surface leads to receptor activation
and increased intracellular Ca2thorn cyclic adenosine
monophosphate (cAMP) levels subsequently decrease
which leads to increased platelet aggregation and
releaseof further activatingfactors Vorapaxar inhibits
PAR-1 thereby signi1047297cantly reducing thrombin-
mediated platelet activation
T he T RA 2P-TIMI 50 trial (Thrombin Receptor
Antagonist for Secondary PreventionndashThrombolysis
in Myocardial Infarction Study Group) studied vor-
apaxar sulfate 25 mg daily versus placebo (ASA and
or clopidogrel therapy at the investigatorsrsquo discre-
tion) among 26449 patients with a recent myocardial
infarction recent ischemic stroke or symptomatic
PAD At 3 years there was a signi1047297cant reduction in
the primary endpoint of MACE (absolute event rates
93 vs 105 HR 087 95 CI 080 to 094
p lt 0001) (79) After 2 years the data and safety
monitoring board recommended stopping the study
drug in the patient subgroup entered with prior
ischemic stroke because of an increased risk of
intracranial hemorrhage Among the 3787 patients
with PAD the majority were treated with aspirin
monotherapy plus vorapaxar or placebo The reduc-
tion in MACE was not statistically signi1047297cant in those
assigned to vorapaxar (absolute event rates 113 vs
119 HR 094 95 CI 078 to 114) Similarly
negative results were observed among patients with
PAD who were enrolled in the TRACER (Thrombin
Receptor Antagonist for Clinical Event Reduction in
Acute Coronary Syndrome) trial (86) Additionally
vorapaxar is associated with a signi1047297cantly increased
risk of major bleeding However in both of these
trials there were relatively few MACE in the PAD
subgroup The PAD group was underpowered to draw
any conclusions on ef 1047297cacy
Pre-speci1047297ed analysis of limb-related outcomes in
the TRA 2P-TIMI 50 trial demonstrated that patients
assigned to vorapaxar had signi1047297cantly reduced rates
of acute limb ischemia (23 vs 39 HR 058 95
CI 039 to 086 p frac14 0006) as well as peripheral
artery revascularization (184 vs 222 HR 084
95 CI 073 to 097 p frac14 0017) during the 3-yearfollow-up (Figure 2) (87) These ef 1047297cacy endpoints
must be balanced by a signi1047297cantly increased rate of
major bleeding among patients prescribed vorapaxar
Further research into the mechanism by which
vorapaxar led to improved limb outcomes is required
to fully understand these effects
CELL-BASED AND ANGIOGENIC THERAPIES
Modulation and enhancement of lower-extremity
blood 1047298ow via angiogenesis arteriogenesis or vas-
culogenesis could provide a promising breakthrough
therapy for patients with PAD (88) Additionally

there has been much interest in the use of stem cellndash
derived endothelial cells or modi1047297cation of resident
stem cells (89) Potential bene1047297ts of these therapies
include improved wound healing and limb salvage
among patients with CLI as well as improved clau-
dication distance To date numerous cell-based and
angiogenic therapies have been tested and despite
promising results in early clinical trials none of these
agents have shown bene1047297t in larger trials
ONGOING CLINICAL TRIALS
There are currently 2 clinical trials studying novel
antiplatelet and anticoagulant agents to reduce MACE
and potentially modify limb-related outcomes
EUCLID (Study Comparing Cardiovascular Effects of
Ticagrelor and Clopidogrel in Patients With Periph-eral Artery Disease) is a randomized blinded double-
dummy trial comparing ticagrelor 90 mg twice daily
to clopidogrel monotherapy among 13500 patients
with PAD (90) All patients are tested for clopidogrel
resistance before randomization The primary
endpoint is a composite of MACE and results are
expected in late 2016 The COMPASS (Rivaroxaban for
the Prevention of Major Cardiovascular Events in
Coronary or Peripheral Artery Disease) trial is evalu-
ating low-dose rivaroxaban alone versus placebo
aspirin alone or rivaroxaban and aspirin among
21400 patients with a history of myocardial infarc-tion or PAD the primary endpoint of this trial is a
composite of MACE (91)
ENDOVASCULAR THERAPY
Endovascular revascularization plays a key role in the
management of patients with PAD Patients with sta-
ble cl audication have a low ris k of lim b loss but may be
severely limited by their symptoms In most circum-
stances patients with claudication should be offered a
trial of cilostazol and an exercise program as initial
therapy If the patient is not satis1047297ed after a trial of
medical therapy endovascular revascularization can be consi dere d Patie nts with CLI require more urgent
revascularization because of an increased riskof tissue
loss and amputation as well as an extremely high risk
of cardiovascular events (92)
There are 2 well-established classi1047297cation schemes
to describe the severity of PAD The 1047297rst is a func-
tional assessment (Fontaine or Rutherford classi1047297ca-
tion [RC]) (Table 2) and the second is an anatomic
lesion classi1047297cation (Trans-Atlantic Inter-Society
Consensus [TASC]) (Table 3) (45) In addition there
has been recent interest in the angiosome concept in
helping to in1047298uence optimal revascularization stra-tegies for limb salvage (93) An angiosome is an
anatomic unit of tissue (consisting of skin subcu-
taneous tissue fascia muscle and bone) that is fed
by a source arte ry and drai ned by speci1047297c veins
If the patient is a candidate for either endovascular
or open surgery the less invasive option (ie an
endovascular-1047297rst strategy) is the current standard of
care The selection of a complex lesion (TASC D) for
endovascular therapy will vary with the skill and
experience of the interventionalist The goal in
treating a patient who has functional impairment
because of claudi cation is dura ble relief of symptoms
In patients with CLI and a threatened limb or tissueloss the goal is rapid reperfusion of the ischemic

AORTOILIAC OCCLUSIVE DISEASE
There has been a practice shift over the past 25 years
as the treatment of aortoiliac disease transitioned
from open surgery with aortobiiliac or aortobifemoral
bypass to endovascular trea tment s for comple x and
diffuse disease (TASC D) This preference for less
invasive therapy is evidence based and driven by
shorter length of stay (or treatment as an outpatient
entirely) and lower periprocedural morbidity and
mortality rates while achieving comparable patency
rates (4- to 5-year primary patency of 60 to 86
with secondary patency rates of 80 to 98) (94)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) In 2011 the European Society of Car-
diology (ESC) (3) and ACCAHA PAD guidelines (2)
recommended an endovascular-1047297rst approach for
aortoiliac lesions recommended that borderline
lesions be assessed with hemodynamic gradients and
supported primary stent placement in the aortoiliac
arteries (Table 4) The current expert consensus
document from the Society for Cardiac Angiography
and Interventions (SCAI) on appropriate use criteria
(AUC) for aortoiliac intervention are similar to the
current guidelines (95)

Treatment of TASC A B C and D Iliac Lesions) re-
ported 100 technical success in 325 patients with
aortoiliac lesions with a 24-month primary patency
rate of 879 (96) Neither TASC category nor lesion
length was predictive of restenosis These data
further support the endovascular-1047297rst strategy
regardless of TASC classi1047297cation and take into
consideration the evolution of devices (ie re-entry
catheters crossing devices and stents) which
improve success rates for the most complex lesions
COMMON FEMORAL DISEASE
Patients with common femoral artery (CFA) disease
are particularly symptomatic because the obstruction
not only occurs proximal to the super1047297cial femoral
artery (SFA) but also proximal to the deep femoralartery (profunda femoris) which is the major collat-
eral artery supplying blood to the lower limb when
there is SFA obstruction Traditionally common
femoral endarterectomy has been the CFA revascu-
larization procedure of choice (23) although
advances in endovascular therapy have shown some
promising results (97) A review of the National Sur-
gical Quality Improvement Program database for 2005
to 2010 found a combined mortality and morbidity
rate of 15 for common femoral endarterectomy
which was higher than expected (98) Patients
requiring CFA revascularization who are at increasedsurgical risk may be considered for less invasive
endovascular options
FEMORAL-POPLITEAL DISEASE
This segment begins at the bifurcation of the CFA into
the SFA and the deep femoral (profunda femoris)
artery The SFA is subject to 1047298exion elongation
compression and torsion unlike any other lower-
extremity artery This complexity leads to many
challenges for endovascular technology but despite
this an endovascular-1047297rst approach is currently thestandard of therapy for the majority of lesions
becau se of the very high proce dural success rate and
low risk (3) Some of the most lengthy and complex
lesions (TASC D) are more approachable because of
the re-entry and crossing devices more experienced
operators drug-eluting stents (DES) (99100) and
drug-coated balloons (DCBs) (101ndash107) that promise
improved long-term patency for patients with clau-
dication (99100103105)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines and the AUC documentfrom the SCAI recommend revascularization in
femoral-popliteal lesions for patients with CLI or for
patients with claudication who have had a suboptimal
r espon se to a tr ial of e xer cise (Tab le 5) An
endovascular-1047297rst approach is recommended for
TASC A through C lesions and is a reasonable option
for TASC D lesions depending on the experience of
the operator the patientrsquos comorbidities and proce-
dure safety (Table 5) (2395)
The 2 guidelines are in con1047298ict over the use of
primary stent placement in the femoral-popliteal ar-
teries with the ACCAHA guideline giving it a Class III
recommendation (do not do) and the ESC guideline
making primary femoral stenting reasonable 1047297rst-line
therapy (Class IIa) for intermediate-length lesions
(108109) The current evidence from several ran-
domized controlled trials supports primary stenting
in intermediate-length femoral stenoses and occlu-
sions (108ndash110) The soon-to-be-published updatedACCAHA guidelines will readdress this issue In
current practice the standard is to primarily stent
intermediate to long SFA lesions
The ACCAHA guideline broadly lump stents
togetherwith atherectomy devicescryotherapy laser
and cutting balloons stating they may be useful as
salvage therapy (Class IIa) but also stating that their
effectiveness remains to proven (Class IIb) Stents
should be removed from this group because their
effectiveness has been established in intermediate-
length femoral lesions Other than the use of the cut-
ting balloon and rotational atherectomy in lesions thatare resistant to dilation there is no comparative

evidence suggesting that the more expensive athe-
rectomy devices cryoplasty or laser angioplasty
should be preferred over conventional therapy
(percutaneous transluminal angioplasty [PTA] and
bare- metal stents [BMS] ) The ESC guideline disti n-
guishes bare-metal self-expanding stents from
adjunctive devices such as atherectomy devices cit-
i ng the p roven bene1047297t of BMS over PTA in
intermediate-length femoral-popliteal lesions
CLINICAL TRIAL UPDATE Three randomized controlledtrials of self-expanding BMS compared with PTA have
shown that the advantage for primary stenting is
related to lesion length For relatively discrete lesions
(mean 45 mm) (110) there was no advantage for pri-
mary stent placement however 2 other trials
(108109) with longer lesions (gt70 mm) showed a
signi1047297cant patency and functional bene1047297t for primary
femoral-popliteal BMS (Figure 3 Table 6) The proce-
dural success rate of endovascular therapy in
femoral-popliteal lesions is very high but in stable
limb ischemia durable patency remains a barrier
Cilostazol has been shown to reduce 1-year restenosis by more than one-half (20 vs 49 p frac14 00001) in
intermediate-length (128 mm) femoral lesions treated
with self-expanding BMS (114) These results need to
be con1047297rmed before this can be recommended as
standard therapy
Recent randomized controlled trials demonstrating
bene1047297t f or DE S (99100) DC B (103105106) and
covered stents (115ndash117) in femoral-popliteal arteries
will likely result in a change in the guidelines and
indications (Table 6 Figure 3)
There hasbeen some enthusiasm for self-expanding
covered (expanded polytetra1047298uoroethylene) stent
grafts in complex or lengthy femoral-popliteal seg-
ments Two randomized trials comparing covered
stents to BMS had divergent results One showed a
bene1047297t for 2-year primary patency but no difference in
target-lesion revascularization (TLR) or clinical out-
comes (116) whereas the other in longer (gt8 cm) le-
sions found no difference for primary patency (115ndash
117) When covered stents were compared with
above-the-knee femoral bypass with synthetic graft
material in a broad range of SFA lesion types (TASC A
thru D) no difference was found in the 4-year primary
patency between the 2 options (118)
The Zilver paclitaxel-eluting self-expanding DES
was superior to PTA in a randomized femoral-
popliteal trial with 1-year patency rates of 831 for
primary DES and 328 for PTA (p lt 0001) (Figure 3
Table 6) (99) There was also a 1-year patency
advantage for provisional DES after failed PTA
(899) compared with provisional BMS (730
p frac14 001) The bene1047297t was sustained at 2 years with
primary patency for the DES (748) signi1047297cantly
better t han PTA (265 p lt 001) (100) To date there
has been no head-to-head comparison of primary DES
to either BMS or DCB in femoral-popliteal arteries
but Zelle r et al (104) published a propensity scorendash
based compar ison of DES and DCB in conse cutive
patients with TASC C and D long (gt10 cm) lesions and
found no signi1047297cant differences in 1-year patency
(Figure 3 Table 6)
DCBs offer the promise of improved patency with areduced need for stents This is particularly important
in the dynamic environment of the super1047297cial femoral
and popliteal arteries where mechanical fatigue may
lead to stent fracture and increased risk of in-stent
restenosis Each DCB is unique with respect to the
paclitaxel dose (varying from 2 to 35 mgmm2) the
carrier molecule (excipient) the balloon material and
the coating technology used Superiority for paclitaxel
DCB over PTA was 1047297rst reported in 2008 (101102)
(Figure 3 Table 6) Subsequently new DCBs have
emerged including the INPACT (105106111113) and
the Lutonix (103106) balloons both of which showedclinical superiority to PTA in femoral-popliteal lesions

fewer repeat interventions Five-year follow-up

TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

For individuals with combined in1047298ow andout1047298ow disease with CLI in1047298ow lesionsshould be addressed 1047297rst (Class I Level
of Evidence C)
For patients with limb-threatening lower-extremity ischemia and an estimated lifeexpectancy 2 years in whom anautogenous vein conduit is not availableballoon angioplasty is reasonable toperform when possible as the initialprocedure to improve distal blood 1047298ow(Class IIa Level of Evidence B)
For infrapopliteal lesionsangioplasty is the preferredtechnique and stentimplantation should beconsidered only in the caseof insuf 1047297cient PTA (Class IIa

The effectiveness of uncoateduncoveredstents atherectomy cutting balloonsthermal devices and lasers for thetreatment of infrapopliteal lesions(except to salvage a suboptimal resultfrom balloon dilation) is not wellestablished (Class IIb Level of

When revascularization in theinfrapopliteal segment isindicated the endovascular-1047297rst strategy should beconsidered (Class IIa Level
of Evidence C)
Primary stent placement is not recommendedin the femoral popliteal or tibial arteries(Class III Level of Evidence C)
Surgical and endovascular intervention is notindicated in patients with severedecrements in limb perfusion (egABI lt04) in the absence of clinicalsymptoms of CLI (Class III Level of

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

reducing variation Accreditation for Cardiovascular
Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous
improvement Payers and regulators should require
or reward independent accreditation to support
value-based health care
CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

there has been much interest in the use of stem cellndash
derived endothelial cells or modi1047297cation of resident
stem cells (89) Potential bene1047297ts of these therapies
include improved wound healing and limb salvage
among patients with CLI as well as improved clau-
dication distance To date numerous cell-based and
angiogenic therapies have been tested and despite
promising results in early clinical trials none of these
agents have shown bene1047297t in larger trials
ONGOING CLINICAL TRIALS
There are currently 2 clinical trials studying novel
antiplatelet and anticoagulant agents to reduce MACE
and potentially modify limb-related outcomes
EUCLID (Study Comparing Cardiovascular Effects of
Ticagrelor and Clopidogrel in Patients With Periph-eral Artery Disease) is a randomized blinded double-
dummy trial comparing ticagrelor 90 mg twice daily
to clopidogrel monotherapy among 13500 patients
with PAD (90) All patients are tested for clopidogrel
resistance before randomization The primary
endpoint is a composite of MACE and results are
expected in late 2016 The COMPASS (Rivaroxaban for
the Prevention of Major Cardiovascular Events in
Coronary or Peripheral Artery Disease) trial is evalu-
ating low-dose rivaroxaban alone versus placebo
aspirin alone or rivaroxaban and aspirin among
21400 patients with a history of myocardial infarc-tion or PAD the primary endpoint of this trial is a
composite of MACE (91)
ENDOVASCULAR THERAPY
Endovascular revascularization plays a key role in the
management of patients with PAD Patients with sta-
ble cl audication have a low ris k of lim b loss but may be
severely limited by their symptoms In most circum-
stances patients with claudication should be offered a
trial of cilostazol and an exercise program as initial
therapy If the patient is not satis1047297ed after a trial of
medical therapy endovascular revascularization can be consi dere d Patie nts with CLI require more urgent
revascularization because of an increased riskof tissue
loss and amputation as well as an extremely high risk
of cardiovascular events (92)
There are 2 well-established classi1047297cation schemes
to describe the severity of PAD The 1047297rst is a func-
tional assessment (Fontaine or Rutherford classi1047297ca-
tion [RC]) (Table 2) and the second is an anatomic
lesion classi1047297cation (Trans-Atlantic Inter-Society
Consensus [TASC]) (Table 3) (45) In addition there
has been recent interest in the angiosome concept in
helping to in1047298uence optimal revascularization stra-tegies for limb salvage (93) An angiosome is an
anatomic unit of tissue (consisting of skin subcu-
taneous tissue fascia muscle and bone) that is fed
by a source arte ry and drai ned by speci1047297c veins
If the patient is a candidate for either endovascular
or open surgery the less invasive option (ie an
endovascular-1047297rst strategy) is the current standard of
care The selection of a complex lesion (TASC D) for
endovascular therapy will vary with the skill and
experience of the interventionalist The goal in
treating a patient who has functional impairment
because of claudi cation is dura ble relief of symptoms
In patients with CLI and a threatened limb or tissueloss the goal is rapid reperfusion of the ischemic

There has been a practice shift over the past 25 years
as the treatment of aortoiliac disease transitioned
from open surgery with aortobiiliac or aortobifemoral
bypass to endovascular trea tment s for comple x and
diffuse disease (TASC D) This preference for less
invasive therapy is evidence based and driven by
shorter length of stay (or treatment as an outpatient
entirely) and lower periprocedural morbidity and
mortality rates while achieving comparable patency
rates (4- to 5-year primary patency of 60 to 86
with secondary patency rates of 80 to 98) (94)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) In 2011 the European Society of Car-
diology (ESC) (3) and ACCAHA PAD guidelines (2)
recommended an endovascular-1047297rst approach for
aortoiliac lesions recommended that borderline
lesions be assessed with hemodynamic gradients and
supported primary stent placement in the aortoiliac
arteries (Table 4) The current expert consensus
document from the Society for Cardiac Angiography
and Interventions (SCAI) on appropriate use criteria
(AUC) for aortoiliac intervention are similar to the
current guidelines (95)

Treatment of TASC A B C and D Iliac Lesions) re-
ported 100 technical success in 325 patients with
aortoiliac lesions with a 24-month primary patency
rate of 879 (96) Neither TASC category nor lesion
length was predictive of restenosis These data
further support the endovascular-1047297rst strategy
regardless of TASC classi1047297cation and take into
consideration the evolution of devices (ie re-entry
catheters crossing devices and stents) which
improve success rates for the most complex lesions
COMMON FEMORAL DISEASE
Patients with common femoral artery (CFA) disease
are particularly symptomatic because the obstruction
not only occurs proximal to the super1047297cial femoral
artery (SFA) but also proximal to the deep femoralartery (profunda femoris) which is the major collat-
eral artery supplying blood to the lower limb when
there is SFA obstruction Traditionally common
femoral endarterectomy has been the CFA revascu-
larization procedure of choice (23) although
advances in endovascular therapy have shown some
promising results (97) A review of the National Sur-
gical Quality Improvement Program database for 2005
to 2010 found a combined mortality and morbidity
rate of 15 for common femoral endarterectomy
which was higher than expected (98) Patients
requiring CFA revascularization who are at increasedsurgical risk may be considered for less invasive
endovascular options
FEMORAL-POPLITEAL DISEASE
This segment begins at the bifurcation of the CFA into
the SFA and the deep femoral (profunda femoris)
artery The SFA is subject to 1047298exion elongation
compression and torsion unlike any other lower-
extremity artery This complexity leads to many
challenges for endovascular technology but despite
this an endovascular-1047297rst approach is currently thestandard of therapy for the majority of lesions
becau se of the very high proce dural success rate and
low risk (3) Some of the most lengthy and complex
lesions (TASC D) are more approachable because of
the re-entry and crossing devices more experienced
operators drug-eluting stents (DES) (99100) and
drug-coated balloons (DCBs) (101ndash107) that promise
improved long-term patency for patients with clau-
dication (99100103105)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines and the AUC documentfrom the SCAI recommend revascularization in
femoral-popliteal lesions for patients with CLI or for
patients with claudication who have had a suboptimal
r espon se to a tr ial of e xer cise (Tab le 5) An
endovascular-1047297rst approach is recommended for
TASC A through C lesions and is a reasonable option
for TASC D lesions depending on the experience of
the operator the patientrsquos comorbidities and proce-
dure safety (Table 5) (2395)
The 2 guidelines are in con1047298ict over the use of
primary stent placement in the femoral-popliteal ar-
teries with the ACCAHA guideline giving it a Class III
recommendation (do not do) and the ESC guideline
making primary femoral stenting reasonable 1047297rst-line
therapy (Class IIa) for intermediate-length lesions
(108109) The current evidence from several ran-
domized controlled trials supports primary stenting
in intermediate-length femoral stenoses and occlu-
sions (108ndash110) The soon-to-be-published updatedACCAHA guidelines will readdress this issue In
current practice the standard is to primarily stent
intermediate to long SFA lesions
The ACCAHA guideline broadly lump stents
togetherwith atherectomy devicescryotherapy laser
and cutting balloons stating they may be useful as
salvage therapy (Class IIa) but also stating that their
effectiveness remains to proven (Class IIb) Stents
should be removed from this group because their
effectiveness has been established in intermediate-
length femoral lesions Other than the use of the cut-
ting balloon and rotational atherectomy in lesions thatare resistant to dilation there is no comparative

evidence suggesting that the more expensive athe-
rectomy devices cryoplasty or laser angioplasty
should be preferred over conventional therapy
(percutaneous transluminal angioplasty [PTA] and
bare- metal stents [BMS] ) The ESC guideline disti n-
guishes bare-metal self-expanding stents from
adjunctive devices such as atherectomy devices cit-
i ng the p roven bene1047297t of BMS over PTA in
intermediate-length femoral-popliteal lesions
CLINICAL TRIAL UPDATE Three randomized controlledtrials of self-expanding BMS compared with PTA have
shown that the advantage for primary stenting is
related to lesion length For relatively discrete lesions
(mean 45 mm) (110) there was no advantage for pri-
mary stent placement however 2 other trials
(108109) with longer lesions (gt70 mm) showed a
signi1047297cant patency and functional bene1047297t for primary
femoral-popliteal BMS (Figure 3 Table 6) The proce-
dural success rate of endovascular therapy in
femoral-popliteal lesions is very high but in stable
limb ischemia durable patency remains a barrier
Cilostazol has been shown to reduce 1-year restenosis by more than one-half (20 vs 49 p frac14 00001) in
intermediate-length (128 mm) femoral lesions treated
with self-expanding BMS (114) These results need to
be con1047297rmed before this can be recommended as
standard therapy
Recent randomized controlled trials demonstrating
bene1047297t f or DE S (99100) DC B (103105106) and
covered stents (115ndash117) in femoral-popliteal arteries
will likely result in a change in the guidelines and
indications (Table 6 Figure 3)
There hasbeen some enthusiasm for self-expanding
covered (expanded polytetra1047298uoroethylene) stent
grafts in complex or lengthy femoral-popliteal seg-
ments Two randomized trials comparing covered
stents to BMS had divergent results One showed a
bene1047297t for 2-year primary patency but no difference in
target-lesion revascularization (TLR) or clinical out-
comes (116) whereas the other in longer (gt8 cm) le-
sions found no difference for primary patency (115ndash
117) When covered stents were compared with
above-the-knee femoral bypass with synthetic graft
material in a broad range of SFA lesion types (TASC A
thru D) no difference was found in the 4-year primary
patency between the 2 options (118)
The Zilver paclitaxel-eluting self-expanding DES
was superior to PTA in a randomized femoral-
popliteal trial with 1-year patency rates of 831 for
primary DES and 328 for PTA (p lt 0001) (Figure 3
Table 6) (99) There was also a 1-year patency
advantage for provisional DES after failed PTA
(899) compared with provisional BMS (730
p frac14 001) The bene1047297t was sustained at 2 years with
primary patency for the DES (748) signi1047297cantly
better t han PTA (265 p lt 001) (100) To date there
has been no head-to-head comparison of primary DES
to either BMS or DCB in femoral-popliteal arteries
but Zelle r et al (104) published a propensity scorendash
based compar ison of DES and DCB in conse cutive
patients with TASC C and D long (gt10 cm) lesions and
found no signi1047297cant differences in 1-year patency
(Figure 3 Table 6)
DCBs offer the promise of improved patency with areduced need for stents This is particularly important
in the dynamic environment of the super1047297cial femoral
and popliteal arteries where mechanical fatigue may
lead to stent fracture and increased risk of in-stent
restenosis Each DCB is unique with respect to the
paclitaxel dose (varying from 2 to 35 mgmm2) the
carrier molecule (excipient) the balloon material and
the coating technology used Superiority for paclitaxel
DCB over PTA was 1047297rst reported in 2008 (101102)
(Figure 3 Table 6) Subsequently new DCBs have
emerged including the INPACT (105106111113) and
the Lutonix (103106) balloons both of which showedclinical superiority to PTA in femoral-popliteal lesions

TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

reducing variation Accreditation for Cardiovascular
Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous
improvement Payers and regulators should require
or reward independent accreditation to support
value-based health care
CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

AORTOILIAC OCCLUSIVE DISEASE
There has been a practice shift over the past 25 years
as the treatment of aortoiliac disease transitioned
from open surgery with aortobiiliac or aortobifemoral
bypass to endovascular trea tment s for comple x and
diffuse disease (TASC D) This preference for less
invasive therapy is evidence based and driven by
shorter length of stay (or treatment as an outpatient
entirely) and lower periprocedural morbidity and
mortality rates while achieving comparable patency
rates (4- to 5-year primary patency of 60 to 86
with secondary patency rates of 80 to 98) (94)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) In 2011 the European Society of Car-
diology (ESC) (3) and ACCAHA PAD guidelines (2)
recommended an endovascular-1047297rst approach for
aortoiliac lesions recommended that borderline
lesions be assessed with hemodynamic gradients and
supported primary stent placement in the aortoiliac
arteries (Table 4) The current expert consensus
document from the Society for Cardiac Angiography
and Interventions (SCAI) on appropriate use criteria
(AUC) for aortoiliac intervention are similar to the
current guidelines (95)

Treatment of TASC A B C and D Iliac Lesions) re-
ported 100 technical success in 325 patients with
aortoiliac lesions with a 24-month primary patency
rate of 879 (96) Neither TASC category nor lesion
length was predictive of restenosis These data
further support the endovascular-1047297rst strategy
regardless of TASC classi1047297cation and take into
consideration the evolution of devices (ie re-entry
catheters crossing devices and stents) which
improve success rates for the most complex lesions
COMMON FEMORAL DISEASE
Patients with common femoral artery (CFA) disease
are particularly symptomatic because the obstruction
not only occurs proximal to the super1047297cial femoral
artery (SFA) but also proximal to the deep femoralartery (profunda femoris) which is the major collat-
eral artery supplying blood to the lower limb when
there is SFA obstruction Traditionally common
femoral endarterectomy has been the CFA revascu-
larization procedure of choice (23) although
advances in endovascular therapy have shown some
promising results (97) A review of the National Sur-
gical Quality Improvement Program database for 2005
to 2010 found a combined mortality and morbidity
rate of 15 for common femoral endarterectomy
which was higher than expected (98) Patients
requiring CFA revascularization who are at increasedsurgical risk may be considered for less invasive
endovascular options
FEMORAL-POPLITEAL DISEASE
This segment begins at the bifurcation of the CFA into
the SFA and the deep femoral (profunda femoris)
artery The SFA is subject to 1047298exion elongation
compression and torsion unlike any other lower-
extremity artery This complexity leads to many
challenges for endovascular technology but despite
this an endovascular-1047297rst approach is currently thestandard of therapy for the majority of lesions
becau se of the very high proce dural success rate and
low risk (3) Some of the most lengthy and complex
lesions (TASC D) are more approachable because of
the re-entry and crossing devices more experienced
operators drug-eluting stents (DES) (99100) and
drug-coated balloons (DCBs) (101ndash107) that promise
improved long-term patency for patients with clau-
dication (99100103105)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines and the AUC documentfrom the SCAI recommend revascularization in
femoral-popliteal lesions for patients with CLI or for
patients with claudication who have had a suboptimal
r espon se to a tr ial of e xer cise (Tab le 5) An
endovascular-1047297rst approach is recommended for
TASC A through C lesions and is a reasonable option
for TASC D lesions depending on the experience of
the operator the patientrsquos comorbidities and proce-
dure safety (Table 5) (2395)
The 2 guidelines are in con1047298ict over the use of
primary stent placement in the femoral-popliteal ar-
teries with the ACCAHA guideline giving it a Class III
recommendation (do not do) and the ESC guideline
making primary femoral stenting reasonable 1047297rst-line
therapy (Class IIa) for intermediate-length lesions
(108109) The current evidence from several ran-
domized controlled trials supports primary stenting
in intermediate-length femoral stenoses and occlu-
sions (108ndash110) The soon-to-be-published updatedACCAHA guidelines will readdress this issue In
current practice the standard is to primarily stent
intermediate to long SFA lesions
The ACCAHA guideline broadly lump stents
togetherwith atherectomy devicescryotherapy laser
and cutting balloons stating they may be useful as
salvage therapy (Class IIa) but also stating that their
effectiveness remains to proven (Class IIb) Stents
should be removed from this group because their
effectiveness has been established in intermediate-
length femoral lesions Other than the use of the cut-
ting balloon and rotational atherectomy in lesions thatare resistant to dilation there is no comparative

evidence suggesting that the more expensive athe-
rectomy devices cryoplasty or laser angioplasty
should be preferred over conventional therapy
(percutaneous transluminal angioplasty [PTA] and
bare- metal stents [BMS] ) The ESC guideline disti n-
guishes bare-metal self-expanding stents from
adjunctive devices such as atherectomy devices cit-
i ng the p roven bene1047297t of BMS over PTA in
intermediate-length femoral-popliteal lesions
CLINICAL TRIAL UPDATE Three randomized controlledtrials of self-expanding BMS compared with PTA have
shown that the advantage for primary stenting is
related to lesion length For relatively discrete lesions
(mean 45 mm) (110) there was no advantage for pri-
mary stent placement however 2 other trials
(108109) with longer lesions (gt70 mm) showed a
signi1047297cant patency and functional bene1047297t for primary
femoral-popliteal BMS (Figure 3 Table 6) The proce-
dural success rate of endovascular therapy in
femoral-popliteal lesions is very high but in stable
limb ischemia durable patency remains a barrier
Cilostazol has been shown to reduce 1-year restenosis by more than one-half (20 vs 49 p frac14 00001) in
intermediate-length (128 mm) femoral lesions treated
with self-expanding BMS (114) These results need to
be con1047297rmed before this can be recommended as
standard therapy
Recent randomized controlled trials demonstrating
bene1047297t f or DE S (99100) DC B (103105106) and
covered stents (115ndash117) in femoral-popliteal arteries
will likely result in a change in the guidelines and
indications (Table 6 Figure 3)
There hasbeen some enthusiasm for self-expanding
covered (expanded polytetra1047298uoroethylene) stent
grafts in complex or lengthy femoral-popliteal seg-
ments Two randomized trials comparing covered
stents to BMS had divergent results One showed a
bene1047297t for 2-year primary patency but no difference in
target-lesion revascularization (TLR) or clinical out-
comes (116) whereas the other in longer (gt8 cm) le-
sions found no difference for primary patency (115ndash
117) When covered stents were compared with
above-the-knee femoral bypass with synthetic graft
material in a broad range of SFA lesion types (TASC A
thru D) no difference was found in the 4-year primary
patency between the 2 options (118)
The Zilver paclitaxel-eluting self-expanding DES
was superior to PTA in a randomized femoral-
popliteal trial with 1-year patency rates of 831 for
primary DES and 328 for PTA (p lt 0001) (Figure 3
Table 6) (99) There was also a 1-year patency
advantage for provisional DES after failed PTA
(899) compared with provisional BMS (730
p frac14 001) The bene1047297t was sustained at 2 years with
primary patency for the DES (748) signi1047297cantly
better t han PTA (265 p lt 001) (100) To date there
has been no head-to-head comparison of primary DES
to either BMS or DCB in femoral-popliteal arteries
but Zelle r et al (104) published a propensity scorendash
based compar ison of DES and DCB in conse cutive
patients with TASC C and D long (gt10 cm) lesions and
found no signi1047297cant differences in 1-year patency
(Figure 3 Table 6)
DCBs offer the promise of improved patency with areduced need for stents This is particularly important
in the dynamic environment of the super1047297cial femoral
and popliteal arteries where mechanical fatigue may
lead to stent fracture and increased risk of in-stent
restenosis Each DCB is unique with respect to the
paclitaxel dose (varying from 2 to 35 mgmm2) the
carrier molecule (excipient) the balloon material and
the coating technology used Superiority for paclitaxel
DCB over PTA was 1047297rst reported in 2008 (101102)
(Figure 3 Table 6) Subsequently new DCBs have
emerged including the INPACT (105106111113) and
the Lutonix (103106) balloons both of which showedclinical superiority to PTA in femoral-popliteal lesions

A CC A HA P AD G ui de li ne s ( 20 06 2 01 1) E SC P AD G ui de li ne s ( 20 11 )
Endovascular procedures are indicated for patientswith a vocational or lifestyle-limiting disabilitydue to intermittent claudication when clinicalfeatures suggest a reasonable likelihood of symptomatic improvement with endovascularintervention and 1) there has been aninadequate response to exercise orpharmacological therapy andor 2) there is avery favorable risk-bene1047297t ratio (eg focalstenosis) (Class I Level of Evidence A)
When revascularization is indicated anendovascular-1047297rst strategy isrecommended in all femoropoplitealTASC AndashC lesions (Class I Level of
Evidence C)
Stents (and other adjunctive techniques such aslasers cutting balloons atherectomy devicesand thermal devices) can be useful in thefemoral popliteal and tibial arteries as salvagetherapy for a suboptimal or failed result fromballoon dilation (eg persistent translesionalgradient residual diameter stenosis gt50 or1047298ow-limiting dissection) (Class IIa Level of
Evidence C)
Primary stent implantation should beconsidered in femoropopliteal TASCB lesions (Class IIa Level of
Evidence A)
The effectiveness of stents atherectomy cuttingballoons thermal devices and lasers for thetreatment of femoral-popliteal arterial lesions isnot well established (except to salvage asuboptimal result from balloon dilation) (Class
IIb Level of Evidence A)
A primary endovascular approach mayalso be considered in TASC D lesionsin patients with severe comorbiditiesif an experienced interventionist isavailable (Class IIb Level of
Evidence C)
Primary stent placement is not recommended in thefemoral popliteal or tibial arteries (Class III
Level of Evidence C)
Endovascular intervention is not indicated asprophylactic therapy in an asymptomatic patientwith lower-extremity PAD (Class III Level of
Evidence C)

fewer repeat interventions Five-year follow-up

(117) The TLR bene1047297t in femoral-popliteal arterieswas

TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

For individuals with combined in1047298ow andout1047298ow disease with CLI in1047298ow lesionsshould be addressed 1047297rst (Class I Level
of Evidence C)
For patients with limb-threatening lower-extremity ischemia and an estimated lifeexpectancy 2 years in whom anautogenous vein conduit is not availableballoon angioplasty is reasonable toperform when possible as the initialprocedure to improve distal blood 1047298ow(Class IIa Level of Evidence B)
For infrapopliteal lesionsangioplasty is the preferredtechnique and stentimplantation should beconsidered only in the caseof insuf 1047297cient PTA (Class IIa

The effectiveness of uncoateduncoveredstents atherectomy cutting balloonsthermal devices and lasers for thetreatment of infrapopliteal lesions(except to salvage a suboptimal resultfrom balloon dilation) is not wellestablished (Class IIb Level of

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

reducing variation Accreditation for Cardiovascular
Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous
improvement Payers and regulators should require
or reward independent accreditation to support
value-based health care
CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

COMMON FEMORAL DISEASE
Patients with common femoral artery (CFA) disease
are particularly symptomatic because the obstruction
not only occurs proximal to the super1047297cial femoral
artery (SFA) but also proximal to the deep femoralartery (profunda femoris) which is the major collat-
eral artery supplying blood to the lower limb when
there is SFA obstruction Traditionally common
femoral endarterectomy has been the CFA revascu-
larization procedure of choice (23) although
advances in endovascular therapy have shown some
promising results (97) A review of the National Sur-
gical Quality Improvement Program database for 2005
to 2010 found a combined mortality and morbidity
rate of 15 for common femoral endarterectomy
which was higher than expected (98) Patients
requiring CFA revascularization who are at increasedsurgical risk may be considered for less invasive
endovascular options
FEMORAL-POPLITEAL DISEASE
This segment begins at the bifurcation of the CFA into
the SFA and the deep femoral (profunda femoris)
artery The SFA is subject to 1047298exion elongation
compression and torsion unlike any other lower-
extremity artery This complexity leads to many
challenges for endovascular technology but despite
this an endovascular-1047297rst approach is currently thestandard of therapy for the majority of lesions
becau se of the very high proce dural success rate and
low risk (3) Some of the most lengthy and complex
lesions (TASC D) are more approachable because of
the re-entry and crossing devices more experienced
operators drug-eluting stents (DES) (99100) and
drug-coated balloons (DCBs) (101ndash107) that promise
improved long-term patency for patients with clau-
dication (99100103105)
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines and the AUC documentfrom the SCAI recommend revascularization in
femoral-popliteal lesions for patients with CLI or for
patients with claudication who have had a suboptimal
r espon se to a tr ial of e xer cise (Tab le 5) An
endovascular-1047297rst approach is recommended for
TASC A through C lesions and is a reasonable option
for TASC D lesions depending on the experience of
the operator the patientrsquos comorbidities and proce-
dure safety (Table 5) (2395)
The 2 guidelines are in con1047298ict over the use of
primary stent placement in the femoral-popliteal ar-
teries with the ACCAHA guideline giving it a Class III
recommendation (do not do) and the ESC guideline
making primary femoral stenting reasonable 1047297rst-line
therapy (Class IIa) for intermediate-length lesions
(108109) The current evidence from several ran-
domized controlled trials supports primary stenting
in intermediate-length femoral stenoses and occlu-
sions (108ndash110) The soon-to-be-published updatedACCAHA guidelines will readdress this issue In
current practice the standard is to primarily stent
intermediate to long SFA lesions
The ACCAHA guideline broadly lump stents
togetherwith atherectomy devicescryotherapy laser
and cutting balloons stating they may be useful as
salvage therapy (Class IIa) but also stating that their
effectiveness remains to proven (Class IIb) Stents
should be removed from this group because their
effectiveness has been established in intermediate-
length femoral lesions Other than the use of the cut-
ting balloon and rotational atherectomy in lesions thatare resistant to dilation there is no comparative

evidence suggesting that the more expensive athe-
rectomy devices cryoplasty or laser angioplasty
should be preferred over conventional therapy
(percutaneous transluminal angioplasty [PTA] and
bare- metal stents [BMS] ) The ESC guideline disti n-
guishes bare-metal self-expanding stents from
adjunctive devices such as atherectomy devices cit-
i ng the p roven bene1047297t of BMS over PTA in
intermediate-length femoral-popliteal lesions
CLINICAL TRIAL UPDATE Three randomized controlledtrials of self-expanding BMS compared with PTA have
shown that the advantage for primary stenting is
related to lesion length For relatively discrete lesions
(mean 45 mm) (110) there was no advantage for pri-
mary stent placement however 2 other trials
(108109) with longer lesions (gt70 mm) showed a
signi1047297cant patency and functional bene1047297t for primary
femoral-popliteal BMS (Figure 3 Table 6) The proce-
dural success rate of endovascular therapy in
femoral-popliteal lesions is very high but in stable
limb ischemia durable patency remains a barrier
Cilostazol has been shown to reduce 1-year restenosis by more than one-half (20 vs 49 p frac14 00001) in
intermediate-length (128 mm) femoral lesions treated
with self-expanding BMS (114) These results need to
be con1047297rmed before this can be recommended as
standard therapy
Recent randomized controlled trials demonstrating
bene1047297t f or DE S (99100) DC B (103105106) and
covered stents (115ndash117) in femoral-popliteal arteries
will likely result in a change in the guidelines and
indications (Table 6 Figure 3)
There hasbeen some enthusiasm for self-expanding
covered (expanded polytetra1047298uoroethylene) stent
grafts in complex or lengthy femoral-popliteal seg-
ments Two randomized trials comparing covered
stents to BMS had divergent results One showed a
bene1047297t for 2-year primary patency but no difference in
target-lesion revascularization (TLR) or clinical out-
comes (116) whereas the other in longer (gt8 cm) le-
sions found no difference for primary patency (115ndash
117) When covered stents were compared with
above-the-knee femoral bypass with synthetic graft
material in a broad range of SFA lesion types (TASC A
thru D) no difference was found in the 4-year primary
patency between the 2 options (118)
The Zilver paclitaxel-eluting self-expanding DES
was superior to PTA in a randomized femoral-
popliteal trial with 1-year patency rates of 831 for
primary DES and 328 for PTA (p lt 0001) (Figure 3
Table 6) (99) There was also a 1-year patency
advantage for provisional DES after failed PTA
(899) compared with provisional BMS (730
p frac14 001) The bene1047297t was sustained at 2 years with
primary patency for the DES (748) signi1047297cantly
better t han PTA (265 p lt 001) (100) To date there
has been no head-to-head comparison of primary DES
to either BMS or DCB in femoral-popliteal arteries
but Zelle r et al (104) published a propensity scorendash
based compar ison of DES and DCB in conse cutive
patients with TASC C and D long (gt10 cm) lesions and
found no signi1047297cant differences in 1-year patency
(Figure 3 Table 6)
DCBs offer the promise of improved patency with areduced need for stents This is particularly important
in the dynamic environment of the super1047297cial femoral
and popliteal arteries where mechanical fatigue may
lead to stent fracture and increased risk of in-stent
restenosis Each DCB is unique with respect to the
paclitaxel dose (varying from 2 to 35 mgmm2) the
carrier molecule (excipient) the balloon material and
the coating technology used Superiority for paclitaxel
DCB over PTA was 1047297rst reported in 2008 (101102)
(Figure 3 Table 6) Subsequently new DCBs have
emerged including the INPACT (105106111113) and
the Lutonix (103106) balloons both of which showedclinical superiority to PTA in femoral-popliteal lesions

TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

reducing variation Accreditation for Cardiovascular
Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous
improvement Payers and regulators should require
or reward independent accreditation to support
value-based health care
CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

evidence suggesting that the more expensive athe-
rectomy devices cryoplasty or laser angioplasty
should be preferred over conventional therapy
(percutaneous transluminal angioplasty [PTA] and
bare- metal stents [BMS] ) The ESC guideline disti n-
guishes bare-metal self-expanding stents from
adjunctive devices such as atherectomy devices cit-
i ng the p roven bene1047297t of BMS over PTA in
intermediate-length femoral-popliteal lesions
CLINICAL TRIAL UPDATE Three randomized controlledtrials of self-expanding BMS compared with PTA have
shown that the advantage for primary stenting is
related to lesion length For relatively discrete lesions
(mean 45 mm) (110) there was no advantage for pri-
mary stent placement however 2 other trials
(108109) with longer lesions (gt70 mm) showed a
signi1047297cant patency and functional bene1047297t for primary
femoral-popliteal BMS (Figure 3 Table 6) The proce-
dural success rate of endovascular therapy in
femoral-popliteal lesions is very high but in stable
limb ischemia durable patency remains a barrier
Cilostazol has been shown to reduce 1-year restenosis by more than one-half (20 vs 49 p frac14 00001) in
intermediate-length (128 mm) femoral lesions treated
with self-expanding BMS (114) These results need to
be con1047297rmed before this can be recommended as
standard therapy
Recent randomized controlled trials demonstrating
bene1047297t f or DE S (99100) DC B (103105106) and
covered stents (115ndash117) in femoral-popliteal arteries
will likely result in a change in the guidelines and
indications (Table 6 Figure 3)
There hasbeen some enthusiasm for self-expanding
covered (expanded polytetra1047298uoroethylene) stent
grafts in complex or lengthy femoral-popliteal seg-
ments Two randomized trials comparing covered
stents to BMS had divergent results One showed a
bene1047297t for 2-year primary patency but no difference in
target-lesion revascularization (TLR) or clinical out-
comes (116) whereas the other in longer (gt8 cm) le-
sions found no difference for primary patency (115ndash
117) When covered stents were compared with
above-the-knee femoral bypass with synthetic graft
material in a broad range of SFA lesion types (TASC A
thru D) no difference was found in the 4-year primary
patency between the 2 options (118)
The Zilver paclitaxel-eluting self-expanding DES
was superior to PTA in a randomized femoral-
popliteal trial with 1-year patency rates of 831 for
primary DES and 328 for PTA (p lt 0001) (Figure 3
Table 6) (99) There was also a 1-year patency
advantage for provisional DES after failed PTA
(899) compared with provisional BMS (730
p frac14 001) The bene1047297t was sustained at 2 years with
primary patency for the DES (748) signi1047297cantly
better t han PTA (265 p lt 001) (100) To date there
has been no head-to-head comparison of primary DES
to either BMS or DCB in femoral-popliteal arteries
but Zelle r et al (104) published a propensity scorendash
based compar ison of DES and DCB in conse cutive
patients with TASC C and D long (gt10 cm) lesions and
found no signi1047297cant differences in 1-year patency
(Figure 3 Table 6)
DCBs offer the promise of improved patency with areduced need for stents This is particularly important
in the dynamic environment of the super1047297cial femoral
and popliteal arteries where mechanical fatigue may
lead to stent fracture and increased risk of in-stent
restenosis Each DCB is unique with respect to the
paclitaxel dose (varying from 2 to 35 mgmm2) the
carrier molecule (excipient) the balloon material and
the coating technology used Superiority for paclitaxel
DCB over PTA was 1047297rst reported in 2008 (101102)
(Figure 3 Table 6) Subsequently new DCBs have
emerged including the INPACT (105106111113) and
the Lutonix (103106) balloons both of which showedclinical superiority to PTA in femoral-popliteal lesions

TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The

Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

reducing variation Accreditation for Cardiovascular
Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous
improvement Payers and regulators should require
or reward independent accreditation to support
value-based health care
CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

For infrapopliteal lesionsangioplasty is the preferredtechnique and stentimplantation should beconsidered only in the caseof insuf 1047297cient PTA (Class IIa

Primary stent placement is not recommendedin the femoral popliteal or tibial arteries(Class III Level of Evidence C)

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

reducing variation Accreditation for Cardiovascular
Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous
improvement Payers and regulators should require
or reward independent accreditation to support
value-based health care
CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

les (Figure 3 Table 6) Thedurability of a paclitaxel-eluting DCB in the SFA has
been demonstra ted at 2 and 5 years (107111)At2years
patients treated with DCB showed signi1047297cantly higher
primary patency than those treated with PTA (789
vs 501 p lt 0001) including lower clinically driven
TLR and similar functional status improvement with
fewer repeat interventions Five-year follow-up
demonstrated thatTLR remainedsigni1047297cantlylower in
the DCB group (21) than for PTA (56 p frac14 00005)
(117) The TLR bene1047297t in femoral-popliteal arterieswas
independent of lesion length There have been no
safety concerns raised for DCB regarding aneurysmformation or 1047297 brotic constr iction
TIBIAL-PERONEAL DISEASE
Infrapopliteal or below-the-knee disease begins with
the popliteal artery at the knee joint and continues
to the tibial and peroneal arteries to the ankle
Revascularization is indicated in patients with CLI
and rarely for those with claudication The BASIL
(Bypass Versus Angioplasty in Severe Ischaemia
of the Leg) trial compared PTA (balloon alone) to
surgery in 452 CLI patients and found no difference
for amputation-free survival but a lower cost withPTA (119)
In general nonambulatory patients with a short-
ened life expectancy and extensive lower-extremity
tissue necrosis should undergo amputation Patients
who have the opportunity to regain ambulatory
function should undergo magnetic resonance angi-
ography computed tomography angiography or
catheter-based angiography to visualize the extent of
lower-extremity vascular disease The goal for
revascularization in patients with CLI is to establish
straight-line 1047298ow from the hip to the foot
CURRENT BEST PRACTICES (EVIDENCE-BASED AND
GUIDELINES) The ACCAHA (2006 2011) and ESC
(2011) PAD guidelines agree that an endovascular-1047297rst
approach is reasonable in patients with CLI and
infrapopliteal arterial disease (Table 7) (23) In can-
didates for endovascular treatment both guidelinessupport PTA as the initial approach with the use of
BMS as needed for bailout lesions (Table 7) (23) The
guidelines however have lagged behind the most
recent evidence demonstrating that DES and DCBs are
superior to angioplasty alone and BMS for infrapo-
pliteal disease (Table 8)
The expert consensus infrapopliteal AUC document
from the SCAI supports endovascular intervention
for patients with severe claudication and focal target
lesions as well as for anatomically suitable lesions
in patients with CLI (RC 4 to 6) (126) Endovascular
therapy may be appropriate in patients with moderateto severe claudication with occlusions or diffuse dis-
ease of 2 or 3 infrapopliteal vessels and for ischemic
rest pain or minor tissue loss with 1- or 2-vessel
infrapopliteal disease It would rarely be appropriate
to perform infrapopliteal intervention for mild clau-
dication (RC 1) or for moderate to severe claudication
with major tissue loss for single-vessel infrapopliteal
obstruction (ie 2 vessels are patent to the foot)
CLINICAL TRIAL UPDATES There have been 4 ran-
domized trials (Table 8) (120ndash122125127) demon-
strating superiority for infrapopliteal DES versus
either PTA BMS or DCB These data provideconvincing evidence favoring infrapopliteal DES over
PTA BMS or DCB for 1) patency 2) reduced rein-
terventions 3) reduced amputation and 4) improved
event-free survival These results are not limited to
patients with CLI because most trials have included
patients with severe claudication It would be
appropriate to revise the guideline statements in
favor of DES for infrapopliteal lesions at this time
The evidence supporting the use of DCB for infra-
popliteal lesions is less certain The DEBATE-BTK
(Drug-Eluting Balloon in Peripheral Intervention for
Below the Knee Angioplasty Evaluation) trial ran-domized 158 infrapopliteal lesions in diabetic

patients with CLI to either DCB (InPact Amphirion
Medtronic Minneapolis Minnesota) or PTA (123) The
mean lesion length was 129 83 mm signi1047297cantly
(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-
nosis at 1 year occurred in 27 of patients in the DCB
gr ou p and 743 of t ho se in th e P TA g rou p
(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor
(124) The trial enrolled 358 CLI patients with infra-
popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

reducing variation Accreditation for Cardiovascular
Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous
improvement Payers and regulators should require
or reward independent accreditation to support
value-based health care
CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

(w100 mm) longer than those in the infrapopliteal
DES randomized trials The primary endpoint reste-

(p lt 0001) Twelve-month major adverse events
occurred less frequently in the DEB (31) than in the
PTA (51) group (p frac14 002) driven mainly by a
reduction in TLR and better ulcer healing However
there was no difference in the rate of amputation
limb salvage or mortality between the groups
In contrast the results of the InPact Deep CLI trial
resulted in the DCB (InPact Amphirion) being with-
drawn from the market worldwide by the sponsor

popliteal lesions and randomized them 21 to DCB and
PTA respectively The restenosis rate and TLR were
not different between the 2 groups There was anonsigni1047297cant trend toward higher amputation rates
in the DEB (88) compared with the PTA group
(36 p frac14 008) It seems clear that more data and
more experience are needed to understand the rela-
tive bene1047297ts of DEB for infrapopliteal lesions (124)
In practical terms an endovascular-1047297rst approach
is the current standard of care for symptomatic
infrainguinal atherosclerotic disease Adverse peri-
procedural events with endovascular therapy for
the treatment of infrapopliteal disease appear to be
low with mortality rates in observational series lt1
The recent technological advances of DES and DEBswill strengthen this consensus recommendation The
BEST-CLI (Best Endovascular Versus Best Surgical
Therapy in Patients With CLI) trial has just been
launched and will answer the question of whether
surgery in selected patients with CLI and with
good-quality saphenous veins is a better choice than
endovascular therapy (128)
THE FUTURE OF ENDOVASCULAR THERAPY
The emphasis on value-based care that offers the
right procedure for the right patient at the right time
requires justi1047297cation of expensive devices in the
context of cost-conscious medical care Unfortu-
nately we often lack head-to-head comparative data
to determine which device or strategy is preferred for
speci1047297c clinical situations It is reasonable to choose
lower-cost strategies unless there is evidence justi-
fying a more expensive choice
AUC have been introduced in a variety of cardio-
vascular subspecialties AUC are intended to aidclinicians in improving patient quality and safety by
reducing (but not eliminating) variation in clinical
practice Essentially AUC offer care pathways that
are meant to offer guidance It is recognized that
deviation from the care pathway will be the right
thing to do in speci1047297c cases Responsible clinicians
should be able to articulate their reasons for deviating
from the ldquoappropriaterdquo care pathway thereby navi-
gating the Scylla and Charybdis of cost-effectiveness
and clinical necessity
Independent accreditation of hospital facilities
such as noninvasive and invasive laboratories is avaluable tool for benchmarking quality of care and

reducing variation Accreditation for Cardiovascular
Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous
improvement Payers and regulators should require
or reward independent accreditation to support
value-based health care
CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)

reducing variation Accreditation for Cardiovascular
Excellence (ACE) offers on-site reviews for cardiac
peripheral carotid electrophysiology and congenital
heart disease Importantly accreditation must be
independent of professional societies regulators
and payers to avoid bias The value of accreditation
is in establishing ongoing procedures to ensure
quality and safety When done properly independent
accreditation functions more like a coach than a
policeman to promote a culture of continuous
improvement Payers and regulators should require
or reward independent accreditation to support
value-based health care
CONCLUSIONS
Despite the increased prevalence over the past 20
years PAD continues to be underdiagnosed and
undertreated compared with CAD Because most
deaths in patients with PAD are attributable to car-
diovascular disease patients with PAD (even those
who are asymptomatic) who are not diagnosed or
treated will needlessly experience MACE There are
effective therapies to prevent cardiovascular events
yet they are still not offered to a large percentage of
patients with PAD Additionally there have been
many advances in minimally invasive techniques to
improve the circulation to the lower extremities and
in the past decade more physicians have become
competent to provide high-level care to patients with
claudication and CLI The endovascular arena has
changed so dramatically over the past 5 years that it is
dif 1047297cult for the guidelines to keep up with these
changes The goal for the future should be early
identi1047297cation of the PAD patient so that progression to
CLI and amputation can be prevented and appropriate
therapy to prevent MACE can be implemented The
optimal treatment of an individual patient involves a
combination of exercise pharmacological therapy
and revascularization (endovascular or open surgery)
