Phase 4 — The treatment has already been approved. Researchers are tracking how it works in a large number of people over time.
This study compares two approaches for patients who need a mechanical heart pump device (called an LVAD) and have a history of dangerous irregular heartbeats. Half of the patients will receive a catheter ablation procedure — a minimally invasive treatment that uses heat to correct problem areas in the heart — before their pump surgery. The other half will continue taking heart rhythm medications only. The study will track both groups for 18 months to see which approach keeps people healthier and reduces hospital visits.
Dangerous heart rhythms are common in patients needing mechanical heart pumps and can cause serious complications after surgery. Doctors want to know if fixing these rhythms before the pump is implanted — rather than waiting and treating them afterward — helps patients recover better and stay out of the hospital.

If you enroll, you will be randomly assigned to one of two groups. One group will have the ablation procedure done during the same surgery when your heart pump is implanted; the other group will continue taking heart rhythm medications as recommended. After your pump surgery, you will have routine follow-up appointments over 18 months where doctors will monitor your heart rhythm, any complications, hospital visits, and overall health. The study team will collect information about your arrhythmias, medications, and any additional procedures or tests you may need.
