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

PRIMARY outcome

Timeframe: Baseline to 6 months

Population: Some patients did not undergo outcome measures due to inability to come for follow-up due to COVID-19.

Number of patients with reduction ≥ 15% in left ventricular end-systolic volume (LVESV) in each arm of the study.

SECONDARY outcome

Timeframe: Baseline to 6 months

Population: A small number patients were unable to return for follow-up due the the outbreak of COVID-19 and some outcome measures were not completed.

Change in left ventricular ejection fraction from baseline to 6 months. Units are expressed in percent and change may vary from -20% to 20%. More negative numbers are desired representing improvement from baseline to 6 months.
