Key result
Comparative effectiveness of CRT-D versus ICD alone remains unmeasured in this cohort.
Why the study?
The comparative effectiveness of cardiac resynchronization therapy with an ICD versus ICD alone in patients with heart failure and ventricular dyssynchrony was unclear.
Observational
Implantable cardioverter-defibrillators (ICDs) are recommended for many patients with reduced left ventricular ejection fractions. Cardiac resynchronization therapy with an ICD (CRT-D), involving placement of an additional lead in the coronary sinus, is recommended for ICD-eligible patients with heart failure (HF) and electrocardiographic evidence of ventricular dyssynchrony (QRS prolongation). To compare the effectiveness of the two devices …

Joel M. Gore (2014) conducted an observational in Heart failure with reduced left ventricular ejection fraction and ventricular dyssynchrony. Cardiac resynchronization therapy with an ICD (CRT-D) vs. Implantable cardioverter-defibrillators (ICDs) was evaluated. The effectiveness of cardiac resynchronization therapy with an ICD (CRT-D) compared to ICD alone was not reported in the truncated abstract.
