Biventricular Implantable Cardioverter Defibrillators Improve Survival Compared with Biventricular Pacing Alone in Patients with Severe Left Ventricular Dysfunction

Abstract

The findings in this study, although necessarily limited in their interpretation by the absence of treatment randomization, suggest that biventricular ICDs offer a survival benefit compared to biventricular pacing alone. Furthermore, this benefit may be most apparent if other clinical factors do not preclude patient survival >1 year postimplant.
