This study is looking at different ways to help people with heart failure (Heart Failure With Reduced Ejection Fraction, or HFrEF) who have had issues with their heart device leads. Specifically, it compares two methods: Coronary Sinus Lead Revision and surgical Left Ventricular Epicardial Pacing. These are both ways to fix problems when the wires (leads) of a special heart device (biventricular pacing resynchronization, or BVP-CRT) stop working correctly. The study wants to see which of these two approaches is more often needed again (lead revision) right after the procedure. You might be able to join if you are over 18, have HFrEF, and have experienced a problem with your heart device lead that was then fixed using one of these two methods. The study is currently unclear on its recruitment status and plans to include 100 participants.

Study design

This is an observational study, meaning researchers will look at existing patient information rather than giving new treatments. It is a single-center, retrospective study involving 100 participants.

What's involved
