Comparing two pacing methods for lead failure in heart failure
Part of Heart & circulation clinical trials.
This study compares two ways to fix a failed lead in a heart failure pacemaker: placing a new lead on the outside of the heart or using the heart's own electrical system. It follows people whose CRT lead stopped working and was replaced, to see which method works best.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have heart failure with a weak pump (HFrEF).
- You had a special pacemaker called a biventricular pacemaker (CRT).
- One of the leads in a vein on the back of your heart (coronary sinus) stopped working and was replaced with a lead placed either on the heart's surface or deeper in the heart's own wiring.
- Your CRT pacemaker is still helping your symptoms and survival.

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 compares two ways to place a pacemaker lead in the heart for people who have heart failure and a type of irregular heartbeat called atrial fibrillation. The goal is to see which pacing method helps the heart pump blood better.
This study tracks how well a new type of pacemaker lead works for people who need cardiac resynchronization therapy (a special pacemaker for heart failure). It aims to see if this lead is safe and effective for everyday use.
This trial compares two types of pacemaker placement to improve heart function in people with heart failure. One method paces the heart's natural conduction system, while the other paces the lower chambers of the heart. The goal is to find which approach works better for heart resynchronization therapy.
This study compares two ways of using a pacemaker to improve heart function in people with heart failure. It aims to see which method works better for helping the heart pump more efficiently.
This trial compares three types of advanced pacemakers (cardiac resynchronization therapy devices) to see which works best for improving heart function and reducing abnormal heart rhythms in people with heart failure.
