Relative Merits of Left Ventricular Dyssynchrony, Left Ventricular Lead Position, and Myocardial Scar to Predict Long-Term Survival of Ischemic Heart Failure Patients Undergoing Cardiac Resynchronization Therapy

Study Questions:

Does myocardial scar, left ventricular (LV) lead position, or dyssynchrony predict response to cardiac resynchronization therapy (CRT) in heart failure?
