Biventricular vs left bundle pacing for heart failure outcomes
Part of Heart & circulation clinical trials.
This trial compares two types of heart pacing to see which improves outcomes for people with heart failure. It may help those who need pacing to better coordinate heartbeats and relieve symptoms.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have heart failure symptoms for at least 3 months and feel limited by your condition (NYHA class II or higher).
- You’re between 18 and 80 years old, and you can understand the study and sign consent.
- Your heart failure type fits one of these groups: sinus rhythm with weak heart pumping and certain ECG (electrical signal) patterns, or atrial fibrillation with fast/uncontrolled heart rate, or you need continuous heart pacing for a slow heart rate, or you developed heart failure despite a prior pacemaker/defibrillator.
- Your ECG and heart pumping measurements in the last 6 weeks must match the study’s thresholds (including specific QRS duration and LBBB or non-LBBB patterns).
- Your kidney function is not severely reduced (estimated kidney filtration must be 30 or higher).
- You have an expected survival of more than 12 months and can attend follow-up visits.

This trial tests whether a different pacing approach called left bundle branch pacing can improve outcomes and heart structure changes in people who did not improve with standard biventricular CRT. It may help some patients with ongoing heart failure symptoms and weak heart pumping.
This trial compares two types of pacing for people with permanent atrial fibrillation (AF) and a weak heart pump (ejection fraction less than 50%). It tests whether pacing the left bundle branch area works as well as or better than standard biventricular pacing to improve heart function.
This trial compares two types of “left-side” heart pacing to see which one works better in people with weak heart pumping. It may help guide the best pacing choice for improving heart function and symptoms.
This study tests a new way to place a pacemaker lead inside the heart to help it beat more effectively, aiming to improve heart function and symptoms in people with heart failure and a specific electrical problem (left bundle branch block). If you meet the criteria, this could be an option to discuss with your heart doctor.
This trial tests a pacing approach designed to improve how the heart beats in some people with heart failure and a specific heart rhythm pattern on ECG. If you already need a device (CRT-D) based on your results, the study may help see whether this pacing correction improves outcomes.
This study compares different ways of pacing the heart to improve its pumping ability in people with heart failure. It aims to find the best pacing method to help your heart work more efficiently and improve symptoms.
