Key issuesKey issues
LV dilatation no longer required Class IV patients should be ambulatory Reasonable expectation of survival with good functional status for 1 y for CRT-D Evidence is strongest for patients with typical LBBB Similar level of evidence for CRT-P and CRT-D

In favour of implantation of CRT-D♥ Predominantly or exclusively implanted CRT-D♥ Younger age, lower comorbidity and longer life expectancy
In favour of implantation of CRT-P♥ Survival advantage with CRT-D was not shown♥ LVEF increase to > 35% (NO ICD indication in HF)♥ Higher risk of device-related complications with CRT-D

Key issuesKey issues
MADIT-CRT and REVERSE demonstrate reduced morbidity In REVERSE and in MADIT-CRT NYHA I pts had been previously symptomatic Improvement primarily seen in pts with QRS ≥150 ms and/or typical LBBB. In MADIT-CRT, women with LBBB demonstrated a particularly favourable response Survival advantage not established In MADIT-CRT the extent of reverse remodelling was concordant with and predictive of improvement in clinical outcomes

CRT and PERMANENT AFibCRT and PERMANENT AFib
Key issuesKey issues
Approximately one-fifth of CRT implantations in Europe are inpatients with permanent AF NYHA class III/IV symptoms and an LVEF of ≤35% are well-established indications for ICD Frequent pacing is defined as ≥95% pacemaker dependency Evidence is strongest for patients with an LBBB pattern Insufficient evidence for mortality recommendation

Key issuesKey issues
In patients with a conventional indication for pacing, NYHA III/IV symptoms, an LVEF of ≤35%, and a QRS width of ≥120 ms, a CRT-P/CRT-D is indicated RV pacing will induce dyssynchrony Chronic RV pacing in patients with LV dysfunction should be avoided CRT may permit adequate up-titration of b-blocker treatment

CRT and CRT and RENAL FAILURERENAL FAILURE
Key issuesKey issues
RF is associated with an increased risk for all-cause mortality, largely explained by an increased risk for pump-failure death High creatinine remaines an independent predictor of mortality in CRT recipients RF pts despite ICD implantation extract little, if any, survival benefit from this therapy

Key issuesKey issues
HF is predominantly a disorder of older adults Very few pts over age 75 were enrolled in the major ICD trials None of the CRT trials included pts in this age range With respect to ICDs: high procedural complication rates , short life expectancy, high risk of dying from causes other than SCD ICD is unlikely to be favorable for most pts
