New ablation approach for persistent atrial fibrillation with stroke risk
Part of Heart & circulation clinical trials.
This trial tests a new type of catheter ablation (using heat to create scar lines in the heart) for people with persistent atrial fibrillation who have a higher risk of stroke or bleeding. It aims to see if this approach can help prevent strokes and reduce the need for long-term blood thinners.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have atrial fibrillation (AF) that has lasted more than 7 days.
- You have a higher risk of stroke (CHA2DS2-VASc score of 2 or more).
- You also have at least one of the following: you cannot take blood thinners safely, you had a stroke despite taking blood thinners, you have a high bleeding risk, or you choose not to take blood thinners long-term.
- You have not had a prior catheter ablation for AF.
- Your left atrium is not severely enlarged (smaller than 60 mm on an echo).
- Your AF has not lasted more than 10 years.
- You are not scheduled for heart surgery, and you do not have a blood clot in your heart.

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 study tests a special catheter that uses two types of energy to fix the irregular heartbeats in people with persistent atrial fibrillation (AFib). It aims to see if it's safe and effective in helping restore a normal heart rhythm.
This study tests a new way to treat persistent atrial fibrillation (a type of irregular heartbeat) during your first catheter ablation procedure. The goal is to see if this approach offers better results than the usual care.
This study compares different ways of doing a procedure called catheter ablation to treat a type of atrial fibrillation that lasts longer than 7 days. They want to see if adding an extra step to the standard treatment helps more than just doing the standard treatment alone. If you join, you will be randomly assigned to one of the three treatment groups.
This trial compares two catheter ablation techniques for people with persistent atrial fibrillation (a type of irregular heartbeat that doesn't go away on its own). It will test whether a more extensive ablation (burning more heart tissue) works better than the standard procedure of isolating the pulmonary veins (the veins that bring blood from the lungs to the heart). If you have this condition and have had at least one episode in the past year, this study might help you find a more effective treatment.
This study tests a new way to treat long-lasting atrial fibrillation using focused energy (pulse field ablation) guided by special heart mapping. It may help people who have not improved with medications or have other heart problems like heart failure.
