Summary

This trial tests how different pacemakers affect quality of life, physical activity, heart failure hospitalizations, and mortality in those with heart failure.

See full description

Who is the study for?

This trial is for adults over 18 with heart failure and left ventricular dysfunction (LVEF≤50%), who are on standard heart failure meds, have a wide QRS (≥130 ms), or need/already have >40% right ventricular pacing. It's not for those with short life expectancy, certain preexisting conditions, recent heart attacks or procedures, reversible cardiomyopathies, severe valve disease, or women who are pregnant.Check my eligibility

What is being tested?

The study compares His bundle or Left bundle branch pacing against standard biventricular pacing in improving quality of life and reducing hospitalizations and mortality in patients with systolic dysfunction and wide QRS complex. It also assesses the safety regarding device complications like lead dislodgement and infection.See study design

What are the potential side effects?

Potential side effects may include issues related to the pacemaker such as local infection at the implant site, lead dislodgement requiring re-intervention, bleeding or bruising around the area where the device was implanted.

Trial Design

2Treatment groups

Active Control

Group I: Biventricular Pacing (BiVP)Active Control1 Intervention

Patients with LVEF≤35% at entry will receive a BiV defibrillator which includes implantation of three leads, an endocardial right atrial lead, an endocardial right ventricular ICD lead, and and an epicardial left ventricular lead implanted in a branch of the coronary sinus. Patients with LVEF 36-50% at entry will receive BiV pacemaker which includes implantation of three leads, an endocardial right atrial lead, an endocardial right ventricular pacing lead, and and an epicardial left ventricular lead implanted in a branch of the coronary sinus.

Group II: His/Left Bundle Branch Pacing (His/LBBP)Active Control1 Intervention

Patients with LVEF≤35% at entry will receive a His/LBB defibrillator which includes implantation of three leads, an endocardial right atrial lead, an endocardial right ventricular ICD lead, and an endocardial His-bundle or left bundle branch pacing lead directly pacing the intrinsic conduction system. Patients with LVEF 36-50% at entry will receive His/LBB pacemaker which includes implantation of two leads, an endocardial right atrial lead, and an endocardial His-bundle or left bundle branch pacing lead directly pacing the intrinsic conduction system.
