Comparing two catheters for repeat atrial fibrillation ablation
Part of Heart & circulation clinical trials.
This study compares two types of catheters (AFFERA vs. standard contact-force guided) for a repeat ablation procedure in people whose atrial fibrillation or related symptoms returned after a first ablation. It aims to find which catheter works best for a second treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 85 years old.
- You have already had one catheter ablation for atrial fibrillation, and after that your symptoms or heart rhythm problems came back.
- You are able to follow the study plan and use a small device that checks your heart rhythm at home.
- You have not had more than one previous ablation that included isolating the pulmonary veins.
- Your left upper heart chamber is not too large (under 55 mm on imaging).
- You do not have atrial fibrillation that has been constant for more than 12 months.

This study compares two different catheters used in ablation procedures to treat persistent atrial fibrillation, a type of irregular heartbeat that lasts for weeks or months. The goal is to find out which catheter is more effective at restoring normal rhythm, and you will receive a small monitor under your skin to track your heart for a year.
This trial tests a newer type of energy (pulsed field ablation) against the standard heat-based method (radiofrequency) for people who have already had one ablation and now have atrial fibrillation again. The goal is to see which works better for keeping your heart in a normal rhythm.
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 trial tests a new catheter system to treat atrial fibrillation (AF) by creating small scars in the heart to block faulty signals. It may help people with symptoms that continue despite medication and who are scheduled for a standard ablation procedure.
This trial tests two different catheters that use pulsed field energy to treat atrial fibrillation (a heart rhythm problem). It aims to find which one works better for people who need blood thinners but have a high risk of bleeding.
This trial compares two ways to treat persistent atrial fibrillation (an irregular heartbeat that lasts for months or years). One method uses pulsed field energy and the other uses radiofrequency heat to fix the heart's electrical signals. The goal is to see which method is safer and more effective for patients having their first ablation procedure.
