Pulsed-field ablation for atrial fibrillation
Part of Heart & circulation clinical trials.
This study tests a new way to do a heart procedure (catheter ablation) for people with ongoing atrial fibrillation (an irregular heartbeat). It uses pulsed-field energy to create a block in the heart that stops abnormal electrical signals. The goal is to improve the procedure's success and reduce risks.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are an adult with ongoing atrial fibrillation (not just occasional episodes) that causes symptoms.
- Your doctor has already recommended a catheter ablation (a procedure to fix your heartbeat).
- You have not had a previous ablation on the left upper heart chamber.
- Your heart pumping strength (ejection fraction) is at least 30%.
- You do not have severe lung disease or sleep apnea that would make sedation risky.

This trial tests a new way to treat non-paroxysmal atrial fibrillation (AF) using a focused type of ablation (pulsed-field energy) on specific areas of the heart. It aims to see if targeting the left atrial wall and mitral isthmus can improve outcomes for people who have not had this procedure before.
This trial tests a new type of heart procedure called pulsed field ablation for people with persistent atrial fibrillation (a long-lasting irregular heartbeat). It compares three different ways to use this ablation to try to restore a normal heart rhythm and reduce symptoms.
This trial tests a newer ablation technique called pulsed field ablation to treat atrial fibrillation, a heart rhythm disorder. The goal is to see if this method works well and is safe for patients who need treatment.
This study tests a newer, gentler way to fix irregular heartbeats in people with paroxysmal AF. The treatment uses special energy (pulsed fields) guided by 3D imaging to target the heart tissue causing the problem, and the goal is to restore a normal rhythm with fewer risks.
This study tests a new way to create a 'block' in the heart tissue to help control atrial fibrillation (an irregular heartbeat). The procedure uses a special energy called pulsed field ablation to target a specific area in the heart's left upper chamber and a nearby vein, which may improve the success of the treatment.
This study tests a special catheter that uses pulsed field energy to ablate (destroy) the tiny areas in the heart causing irregular heartbeats. It is designed for people with paroxysmal atrial fibrillation (episodes that come and go) that hasn't been controlled by medication.
