Repeat ablation for atrial fibrillation: with or without back wall treatment
Part of Heart & circulation clinical trials.
This study compares two types of repeat ablation procedures for people with atrial fibrillation that has come back after a first ablation. One procedure targets only the lung veins, and the other also targets the back wall of the heart's upper chamber. The goal is to find out which approach is better at preventing further episodes.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older.
- You have had one previous catheter ablation for atrial fibrillation, but the irregular heartbeats came back.
- Your atrial fibrillation must be confirmed by a doctor within the last 2 years.
- You must be on a blood thinner for at least 4 weeks before the procedure, or have a special heart scan to rule out blood clots.
- You must not have certain heart conditions, like severe heart failure, very large left atrium, or prior heart surgery.

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 ways to treat persistent atrial fibrillation during a catheter ablation procedure. It tests whether adding isolation of the back wall of the left atrium or using alcohol to ablate a small vein near the heart can improve outcomes compared to standard pulmonary vein isolation alone.
This study compares two ways to perform a heart procedure called ablation to treat atrial fibrillation, a condition that causes an irregular heartbeat. The goal is to find out which approach is safer and more effective at restoring a normal heart rhythm.
This trial compares two types of repeat ablation for people whose persistent atrial fibrillation (AF) has come back after a prior procedure. It tests whether adding isolation of the back wall of the heart's left atrium to the standard vein isolation improves outcomes. If you have had up to two prior AF ablations and are willing to be followed, you may qualify.
