B-Left HF: Biventricular Versus Left Univentricular Pacing With Implantable Cardiac Defibrillator (ICD) Back-Up in Heart Failure Patients
The purpose of this study is to demonstrate that biventricular pacing (BiV) and left univentricular (left ventricular [LV] only) pacing are safe and effective for cardiac resynchronization therapy in heart failure patients implanted with a cardiac resynchronization therapy defibrillator (CRT-D) device.
The hypothesis to be tested by this clinical investigation is that patients indicated for an ICD with cardiac resynchronization therapy respond as well to LV only pacing as to BiV pacing.
Device: Cardiac Resynchronization Therapy
|Study Design:||Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Primary Purpose: Treatment
|Official Title:||Biventricular Versus Left Univentricular Pacing With ICD Back-up in Heart Failure Patients|
- The primary objective is to demonstrate that left univentricular pacing is equivalent to biventricular pacing in improving the functional capacity and inducing reverse remodeling.
- The secondary objective of this clinical investigation is to evaluate the proportion of improved patients in each group, using the Heart Failure Clinical Composite Response.
