Cardiac resynchronization treatment (CRT) has moved into the mainstream of patient care after several randomized studies have demonstrated improved quality of life, reversed remodeling, and decreased heart failure hospitalizations. More recently, 2 large studies have demonstrated a mortality benefit of CRT independent of implantable cardioverter defibrillator

This review presents a substudy analysis of the Defibrillators in Non-Ischemic Cardiomyopathy Treatment Evaluation (DEFINITE) trial, which examined the role of prophylactic implantable cardioverter defibrillator (ICD) implantation in patients with nonischemic cardiomyopathy.
