Pulsed field vs. cryoballoon ablation for persistent atrial fibrillation
Part of Heart & circulation clinical trials.
This trial compares two techniques—pulsed field ablation and cryoballoon ablation—to treat persistent atrial fibrillation (a type of irregular heartbeat that lasts less than a year). The goal is to see which method works better and is safer for patients.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 85 years old.
- You have been diagnosed with persistent atrial fibrillation that has lasted less than one year, or you have needed a procedure to restore a normal heartbeat (cardioversion).
- You are eligible for catheter ablation based on current Japanese medical guidelines.
- You do not have atrial fibrillation that comes and goes (paroxysmal) or that has lasted longer than one year (long-standing persistent).
- You are willing and able to give written informed consent.

This trial tests a new type of ablation (pulsed-field) to treat persistent atrial fibrillation (AFib) that lasts more than 7 days. You may qualify if you have symptoms and haven't had other heart ablation procedures except for one specific type.
This trial compares a newer type of ablation (pulsed field) with the standard radiofrequency ablation for people with persistent atrial fibrillation that hasn't been treated with ablation before. The goal is to see which method works better and has fewer risks.
This trial tests a balloon catheter that uses pulsed field energy to treat atrial fibrillation (AF) in people who have tried medication without success. It aims to see how well it works in real-world use.
This trial tests a newer type of ablation (pulsed field ablation) for people with persistent atrial fibrillation who have already had one ablation. The goal is to see if it can fix the heart rhythm problem again.
This trial tests a new procedure called pulsed field ablation to treat persistent atrial fibrillation (long-lasting irregular heartbeat). It compares different ways of using the procedure and may be an option if heart rhythm medicines haven't worked for you.
This trial tests a new type of ablation (pulsed field ablation) against standard radiofrequency ablation for people with persistent atrial fibrillation that hasn't been controlled well by medication. The goal is to see which method works better and is safer.
