Comparing two procedures for persistent atrial fibrillation with enlarged left atrium
Part of Heart & circulation clinical trials.
This study compares two procedures to treat persistent atrial fibrillation in people whose upper left heart chamber is enlarged: catheter ablation (a minimally invasive procedure using a tube through a vein) versus thoracoscopic ablation (a surgical approach using small chest incisions). The goal is to see which method better restores a normal heart rhythm.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 19 years or older.
- You have persistent atrial fibrillation (a heart rhythm problem that lasts for more than a week).
- You have tried or cannot take anti-arrhythmic medications (drugs to control heart rhythm).
- You have an enlarged left atrium (the upper left chamber of the heart is bigger than normal).
- Your symptoms from atrial fibrillation are significant enough to affect daily activities.

This study compares two ways to treat persistent atrial fibrillation (an irregular heartbeat that lasts for a long time). One method uses a catheter to treat the heart from the inside, and the other combines that with a small procedure on the outside of the heart. The goal is to see which approach works better for people whose symptoms haven't improved with medication.
This study compares different ways of doing a procedure called catheter ablation to treat a type of atrial fibrillation that lasts longer than 7 days. They want to see if adding an extra step to the standard treatment helps more than just doing the standard treatment alone. If you join, you will be randomly assigned to one of the three treatment groups.
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 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 study compares two techniques for treating persistent atrial fibrillation: one uses standard anatomy-based ablation, and the other uses a special mapping system to guide the procedure. It aims to find which method works better for people who have not had prior ablation.
This study compares two procedures to treat persistent atrial fibrillation (an irregular heartbeat that lasts more than a week). It looks at whether a newer method (pulsed-field ablation) works better than the standard method (radiofrequency ablation), both combined with a chemical injection to improve treatment success.
