Study of heart rhythm mapping during AF ablation
Part of Heart & circulation clinical trials.
This is an observational study that looks at how a special heart mapping system may affect the procedure and outcomes for people having ablation for persistent atrial fibrillation (AF). It may help doctors better understand what works best and how procedures turn out.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You have persistent AF that has lasted more than 7 days but less than 2 years continuously
- You previously had pulmonary vein isolation, but your AF came back
- At your first procedure, you only had limited extra ablation (for example, a right atrial flutter line)
- You do not have prior ablation in more than one area of the left atrium besides the pulmonary veins
- You can safely take blood thinners (no contraindication), and kidney function is adequate (eGFR 30 or higher)

This study tests a new mapping system that helps doctors see the electrical signals in your heart more clearly during a standard ablation for persistent atrial fibrillation. It may improve the accuracy of the treatment.
This trial tests a new way to treat persistent atrial fibrillation (a type of irregular heartbeat that lasts more than 7 days) using a specialized mapping system. It aims to help people who have not gotten relief from medications or cannot tolerate them.
This study tests a heart rhythm procedure that uses electrical mapping to guide ablation (controlled scarring) of a specific area in the heart's left upper chamber to treat persistent atrial fibrillation—a condition where the heart beats irregularly for more than a week at a time. The goal is to see if this targeted approach helps restore normal heart rhythm.
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.
This trial tests a special catheter to map abnormal heart rhythms like ventricular tachycardia or atrial fibrillation. It may help patients who need a procedure to find and treat the source of these fast or irregular heartbeats.
This trial tests whether using a special heart-mapping device during ablation (a procedure to fix irregular heartbeats) can improve outcomes for people with persistent atrial fibrillation and an enlarged left heart chamber.
