Heat vs. Freezing for the Back of the Heart
Part of Brain & nervous system, Heart & circulation clinical trials.
This trial tests two ways to treat the back wall of the heart's left chamber in people with stubborn atrial fibrillation. It compares radiofrequency (heat) and cryoablation (freezing) to see which is safer and works better.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You have atrial fibrillation that does not get better with medicine.
- Your atrial fibrillation is persistent (lasting more than 7 days) or long-persisting (lasting more than a year).
- You have not had open-heart surgery before.
- You do not have other serious heart problems that need surgery, like a damaged heart valve or a birth defect.

This study compares a newer, faster type of ablation (high-power short-duration) with the standard approach for treating atrial fibrillation. The goal is to see which method is safer and more effective at restoring a normal heart rhythm.
This trial tests a freezing treatment (cryoablation) to fix abnormal heart rhythms during surgery for heart valve problems. It aims to see if the treatment is safe and effective, possibly reducing the need for future heart rhythm issues.
This trial tests whether using freezing (cryoablation) as the first treatment for persistent atrial fibrillation is better than starting with anti-arrhythmic drugs. The goal is to restore a normal heart rhythm and reduce symptoms.
This study compares two heart procedures to treat atrial fibrillation in people who also have valve disease. One is a standard approach and the other adds a bit more treatment to try to prevent the arrhythmia from coming back.
This trial compares two ways to treat persistent atrial fibrillation (an irregular heartbeat that lasts for months or years). One method uses pulsed field energy and the other uses radiofrequency heat to fix the heart's electrical signals. The goal is to see which method is safer and more effective for patients having their first ablation procedure.
This study tests an extra heart ablation procedure for people with persistent atrial fibrillation. It aims to improve the success of the standard treatment by also isolating the back wall of the left atrium, which may help keep your heart rhythm normal longer.
