Comparing two procedures for repeat treatment of atrial fibrillation
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have had at least one prior procedure to treat atrial fibrillation (called a 'scarring' treatment or ablation).
- Your atrial fibrillation symptoms must still be present or your heart rate not well controlled despite medication, at least 2 months after your last procedure.
- You must have either an enlarged left upper heart chamber (atrium) or a high HATCH score (a score based on your health history that estimates stroke risk).
- You must be healthy enough to be able to have both a repeat ablation and a pacemaker with a special procedure to control heart rate.
- You must be willing to fill out questionnaires and give written consent.
- You cannot have severe valve disease, a recent heart attack or stroke (within 3 months), a weak heart pump (ejection fraction below 40%), or an ICD (implanted defibrillator).

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 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.
This trial compares two minimally invasive heart procedures for persistent atrial fibrillation (a type of irregular heartbeat). The aim is to see which one is safer and more effective at restoring a normal heart rhythm.
This trial compares two ways to control atrial fibrillation (an irregular heartbeat) in older patients: destroying a small area of the heart's electrical pathway and implanting a pacemaker, versus a procedure to isolate the veins that trigger the irregular beats. The goal is to see which approach gives you better results and fits your preferences.
This study compares two procedures for people who have both atrial fibrillation (AFib) and heart failure: one that slows the heart's electrical signals (AV node ablation) and one that helps the heart pump in a more coordinated way (cardiac resynchronization). Both are options when medications alone aren't enough, and the goal is to improve symptoms and quality of life.
