Comparing three ablation methods for persistent atrial fibrillation
Part of Heart & circulation clinical trials.
This study compares three approaches to treat persistent atrial fibrillation (AF) that lasts more than 7 days. It tests whether isolating the pulmonary veins alone is enough, or if also targeting low-voltage areas (scarred heart tissue) during either normal rhythm or AF works better.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You have non-paroxysmal atrial fibrillation (AF episodes lasting more than 7 days).
- You have not had a previous ablation for AF, atrial tachycardia, or atypical atrial flutter.
- Your left atrium (upper heart chamber) is not larger than 55 mm on an ultrasound.
- You have not had a bleeding stroke in the last 6 months or a mini-stroke in the last month.
- You are able to sign consent forms and attend follow-up visits.

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 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 study compares two treatments for persistent atrial fibrillation (AF) that lasts more than 7 days but less than 2 years: electrical cardioversion (a shock to reset your heart rhythm) versus catheter ablation (using radio waves to fix the heart's electrical pathways). It aims to find which option works better for patients like you.
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 trial tests two different ablation techniques to treat a type of irregular heartbeat that doesn't go away on its own. It aims to find which approach works better and is safer.
