Summary

This is a randomized, prospective, single-blinded trial to determine the overall rate of successful His-Purkinje conduction system pacing Optimized Trial of Cardiac Resynchronization Therapy (HOT-CRT) versus biventricular pacing using coronary sinus lead (BVP) to compare acute and mid-term outcomes. Acute outcomes include change in QRS duration pre-and post-pacing (degree of QRS narrowing) and incidence of major periprocedural complications (pericardial tamponade, need for lead revision, etc.). Mid-term outcomes include echocardiographic response at 6 months along with a composite clinical outcome of heart failure hospitalization, ventricular arrhythmias, crossover, and all-cause mortality.

Conditions

  • Heart Failure，Congestive
  • Cardiomyopathies
  • Left Ventricular Dysfunction

Interventions

DEVICE

HOT-CRT

Subjects enrolled in the study will receive a permanent cardiac implantable electronic device (CIED) (CRT-pacemaker or CRT-defibrillator) as clinically indicated. Subjects randomized to HOT-CRT will have His bundle pacing lead placed initially to achieve CRT. If complete resynchronization is achieved (BBB normalization) but capture thresholds are high (1.5-2V), the lead may be placed in the distal conduction system (left bundle branch area). If only partial QRS narrowing is achieved, a coronary sinus lead may be placed and left ventricular timing may be optimized to achieve maximal resynchronization.

DEVICE

Biventricular Pacing

Subjects enrolled in the study will receive a permanent CIED (CRT-pacemaker or CRT-defibrillator) as clinically indicated. Subjects randomized to Biventricular pacing will undergo left ventricular lead placement in the coronary sinus venous branches.
