Second heart procedure with or without extra ablation for atrial fibrillation
Part of Heart & circulation clinical trials.
This study compares two ways of doing a repeat heart procedure for atrial fibrillation (an irregular heartbeat). It tests whether adding extra ablation (using energy to destroy small areas of heart tissue) on the back wall of the heart's upper left chamber helps prevent the irregular heartbeat from coming back.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have had atrial fibrillation (irregular heartbeat) that came back after a previous heart procedure to treat it.
- You are at least 18 years old.
- You are planning to have another heart procedure for atrial fibrillation.
- You have been on blood thinners for at least 4 weeks before the procedure, or you have had a special heart scan to make sure there are no blood clots.
- You have not had more than one previous heart procedure for atrial fibrillation, and that procedure only treated the areas around the lung veins.

This trial compares different techniques for a second heart ablation procedure in people with atrial fibrillation (AFib) who have already had one ablation. It aims to find the best approach to stop AFib from coming back.
This study compares two types of ablation (a procedure that uses energy to fix irregular heartbeats) for people with persistent atrial fibrillation. It tests whether adding extra treatment to the back of the heart's left upper chamber helps improve outcomes compared to standard treatment alone.
This trial compares two catheter ablation techniques for people with persistent atrial fibrillation (a type of irregular heartbeat that doesn't go away on its own). It will test whether a more extensive ablation (burning more heart tissue) works better than the standard procedure of isolating the pulmonary veins (the veins that bring blood from the lungs to the heart). If you have this condition and have had at least one episode in the past year, this study might help you find a more effective treatment.
This study compares two extra ablation procedures done along with standard pulmonary vein isolation in people with persistent atrial fibrillation. Both aim to stop abnormal electrical signals that drive atrial fibrillation, and the study will see which approach is safer and more effective.
This study compares two treatments for people with atrial fibrillation (an irregular heartbeat) that keeps coming back after a previous ablation. One treatment is a repeat ablation, and the other is a pacemaker plus a procedure called AV node ablation to control the heart rate. The study aims to see which approach works better.
This trial tests whether adding extra ablation to the standard treatment for atrial fibrillation improves outcomes for patients who do not have damaged heart tissue. It may help people with AF who haven't had ablation before and have a specific area in their heart that could be targeted.
