Comparing two ablation methods for long-standing atrial fibrillation
Part of Heart & circulation clinical trials.
This study tests whether adding extra scar lines (linear ablation) to the standard pulmonary vein isolation (CPVI) is better than CPVI alone for people with long-standing persistent AF that has lasted 1 to 3 years. The goal is to see which approach reduces AF better.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have had continuous atrial fibrillation (AF) for at least 1 year but no more than 3 years.
- You still have AF symptoms despite taking at least one heart rhythm medication.
- Your age is between 18 and 75 years old.
- Your left atrium (upper heart chamber) is enlarged (43–55 mm on an echo).
- You have not had a prior catheter ablation for AF.
- You do not have severe heart disease, other serious health conditions, or a BMI outside 18.5–30.
- You are willing to follow the study plan and sign a consent form.

This trial tests whether adding extra ablation lines to the standard pulmonary vein isolation procedure is more effective for people with persistent atrial fibrillation that hasn't been helped by medications. The goal is to improve symptoms like palpitations, fatigue, and shortness of breath.
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 trial tests a newer, possibly safer way to treat persistent atrial fibrillation using pulsed field ablation. It compares standard vein isolation alone to adding extra ablation spots to improve success.
This study compares two types of ablation (a procedure that uses energy to fix irregular heartbeats) for people with persistent atrial fibrillation. It tests whether adding extra treatment to the back of the heart's left upper chamber helps improve outcomes compared to standard treatment alone.
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 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.
