Study Description

Brief Summary:
Cardiac resynchronization therapy (CRT) is a demonstrably effective device intervention for patients with heart failure with reduced ejection fraction and specific indication. However, many patients with heart failure (HF) are unable to maintain sinus rhythm and approximately 30-36% of CRT patients are in atrial fibrillation (AF).

Condition or disease Intervention/treatment Phase
Systolic Heart Failure Atrial Fibrillation (Permanent) Procedure: Atrioventricular junctional (AVJ) ablation Device: Cardiac resynchronization therapy - defibrillator Not Applicable

Detailed Description:
This study is designed to evaluate if patients with AF indicated for CRT will have significant reduction in left ventricular end-systolic volume when randomized to atrioventricular junction (AVJ) ablation. In this study, subjects will be randomized to receive CRT-D or CRT-D with AVJ ablation. Randomization will be stratified by enrolling center (1:1 ratio).

Arm Intervention/treatment
Active Comparator: CRT-D
Patients will be randomized at enrollment. Patients in this arm of the study will receive cardiac resynchronization therapy with defibrillator (CRT-D).
 Device: Cardiac resynchronization therapy - defibrillator
Insertion of device capable of providing biventricular pacing and cardiac defibrillation
Other Name: CRT-D
Experimental: CRT-D and AVJ Ablation
Patients in this arm of the study will receive CRT-D and undergo atrioventricular junctional (AVJ) ablation.
 Procedure: Atrioventricular junctional (AVJ) ablation
RF energy delivery to AV node to create complete AV block

Device: Cardiac resynchronization therapy - defibrillator
Insertion of device capable of providing biventricular pacing and cardiac defibrillation
Other Name: CRT-D
