Compare two heart-rhythm strategies after CRT for atrial fibrillation
Part of Heart & circulation clinical trials.
This study looks at whether a “rate control” or “rhythm control” approach works better for people with CRT devices who still have atrial fibrillation. It aims to improve heart failure symptoms and help the heart pace more effectively.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You can understand the study, agree to take part, and attend follow-up visits
- You have a CRT device (or are getting one/it is being upgraded) with an atrial lead in place
- Your ECG shows a wide QRS (more than 120 ms), and your heart’s pumping is reduced (EF 35% or less) with heart failure symptoms
- At least 3 months after the CRT procedure, your biventricular pacing is under 95% mainly because of atrial fibrillation
- A doctor recommends AV node ablation as part of your care
- You are expected to live at least 1 year (not less than 1 year)

This study compares two different ablation procedures (treatments that target heart rhythm triggers) for people with atrial fibrillation and reduced heart pumping. It aims to see which approach works best and is safest for improving your heart rhythm when you also have heart failure.
This study compares two treatments for people with atrial fibrillation and heart failure: one is a procedure to fix the irregular heartbeat (AF ablation), and the other involves a different type of pacing for the heart. It aims to find which approach helps you feel better and stay out of the hospital.
This study tests a new way to place pacing leads (thin wires) in the heart to help it beat more effectively in patients with atrial fibrillation (irregular heartbeat) and heart failure. The goal is to improve how well the heart pumps blood and reduce symptoms.
This trial studies whether a strategy to regularize (control) heart rate can improve outcomes in people who have permanent atrial fibrillation and heart failure. It focuses on people with recent heart-failure hospitalization and checks several heart, kidney, and health-condition limits to keep the study safe.
This trial tests a special pacing method (conduction system pacing) combined with a small ablation to control heart rate in people with permanent atrial fibrillation and advanced heart failure. It aims to improve symptoms and potentially avoid the need for a heart transplant or LVAD.
This trial tests whether a catheter procedure that treats atrial fibrillation works better than standard care for people with heart failure with preserved ejection fraction. It aims to improve heart rhythm symptoms and overall outcomes compared with conventional treatment.
