Patient case 1
• 28 year-old-female
• Correction of a partial atrio-ventricular septal defect at
the age of 4 year
• Progressive shortness of breath, no other complaints
• ECG: sinus rhythm
• Echo: no residual shunt at atrio-ventricular level

Importance of recognizing MR mechanism
Asks for valve repair or repacement
May improve with
• medical therapy (ACE-inhibitors,
beta-blockers, diuretics)
• resynchronization therapy
• coronary revascularisation
![Page 11: Mechanisms of mitral regurgitation from Geleijnse - November 2012](https://reader038.vdocuments.site/reader038/viewer/2022103011/5870add11a28ab962d8b62a7/html5/thumbnails/11.jpg)
Importance of recognizing MR mechanism
Primary MR: due to a valvular problem
- valve repair or replacement
Secondary or functional MR: due to a LV problem
- heart failure therapy (ACE-inhibitors, beta-
blockers, diuretics)
- cardiac resynchronization therapy (CRT)
- coronary revascularisation (PCI or CABG)

Importance of MR mechanism: axioma 1
Successful valve repair is preferable to
valve replacement for most patients valve replacement for most patients
with mitral valve disease
![Page 14: Mechanisms of mitral regurgitation from Geleijnse - November 2012](https://reader038.vdocuments.site/reader038/viewer/2022103011/5870add11a28ab962d8b62a7/html5/thumbnails/14.jpg)
Importance of MR mechanism: axiomas
1) successful mitral valve repair is preferable to mitral valve replacement for most patients
2) accurate assessment of the functional anatomy is a prerequisite for successful anatomy is a prerequisite for successful and long-lasting mitral valve repair
3) surgical inspection of the mitral valve in a flaccid arrested heart at the time of surgery does not reflect true functional pathology of the diseased mitral valve

Importance of MR mechanism: axioma 3
Surgical inspection of the mitral
valve in a flaccid arrested heart at
the time of surgery does not reflect the time of surgery does not reflect
true functional pathology of the
diseased mitral valve

Importance of MR mechanism: axioma 4
The preoperative assessment of
the functional pathology of the
mitral valve is as relevant to a mitral valve is as relevant to a
surgeon as a well-charted route to
Curacao is to a pilot before take-off

Type II - Increased motion of the valve leaflets
• Normal = closure below the annular plane with a
coaptation zone of at least 5-8mm
• Billowing = superior displacement past the annular
plane of the body of the leaflet
• PMVL
• AMVL >2mm in LAX or >5mm in 4CH
• Prolapse = superior displacement past the annular
plane of the free margin of the leaflet
• Flail = severe prolapse due to chordal or papillary
muscle rupture or extreme chordal elongation

Recognizing site and extent of prolaps
defines the difficulty of surgery
and (hopefully) thereby and (hopefully) thereby
defines the selection of the surgeon

Patient Case = Mitral valve cleft
• Unusual congenital lesion most often encountered in
association with other congenital heart defects (atrio-
ventricular endocardial cushion defects)
• Responsible for 1/3 of congenital mitral regurgitation
• Cleft diagnosis is difficult because of the position, • Cleft diagnosis is difficult because of the position,
dimensions and shape of the lesion

Conclusions 3D TEE
• easier to understand (surgeon)
• faster (only one recording)
• more accurate (extent)• more accurate (extent)
