Comparing two catheter types for atrial fibrillation ablation
Part of Heart & circulation clinical trials.
This trial compares two types of special catheters (thin tubes) used during a procedure called ablation to treat atrial fibrillation (irregular heartbeat). It aims to see which catheter works better during the procedure, and may help improve future treatments for people with heart rhythm problems.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have been diagnosed with atrial fibrillation (a type of irregular heartbeat) confirmed by a standard test such as an ECG (electrocardiogram), Holter monitor, or heart device.
- Your doctor has determined that you are a good candidate for a procedure called ablation (which uses a catheter to stop the irregular signals in your heart).
- You are 18 years or older.
- You have not had a previous ablation or surgery on the left upper chamber of your heart.
- You do not have a blood clot inside your heart, and you do not have severe mitral valve disease (valve leakage or narrowing).
- If you are a woman under 50, you will need a pregnancy test before the 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 types of specialized catheters used during heart rhythm ablation procedures to help doctors confirm they've created the right burn patterns. If you're having ablation for persistent atrial fibrillation or flutter with complex burn lines planned, this trial may help improve how your procedure is done.
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.
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 different ways of delivering pulsed field ablation—a newer, targeted energy that zaps abnormal heart tissue—for people with atrial fibrillation. It aims to see if a single broader application works as well as a more focused, two-step approach, and it may help you feel better if you have symptoms from this irregular heartbeat.
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.
