Comparing two ablation catheters for persistent atrial fibrillation
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You have persistent atrial fibrillation (continuous for more than 7 days but less than a year)
- You have symptoms from atrial fibrillation, like palpitations, shortness of breath, or fatigue (score of II or higher on the EHRA scale)
- Your doctor plans to do a catheter ablation, either because medications didn't work or as your first-line treatment
- You are willing to have a small implantable heart monitor (loop recorder) placed under your skin to track your heart rhythm for a year
- You have no severe heart enlargement, no blood clot in the left atrium, no prior ablation for afib, no pacemaker/ICD, and no serious heart failure (NYHA class III or IV)

Other trials that look related to this one.
This study compares two ways to treat persistent atrial fibrillation (an irregular heartbeat that lasts for a long time). One method uses a catheter to treat the heart from the inside, and the other combines that with a small procedure on the outside of the heart. The goal is to see which approach works better for people whose symptoms haven't improved with medication.
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 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 trial tests a catheter ablation procedure for people with persistent atrial fibrillation (a type of irregular heartbeat that lasts more than 7 days but less than a year). It aims to see if the procedure is safe and effective for restoring a normal heart rhythm.
