Left Atrial Ablation for Persistent Atrial Fibrillation
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Age 18 or older
- Diagnosed with persistent atrial fibrillation (irregular heartbeat lasting more than 7 days, confirmed on an ECG or heart monitor in the past 12 months)
- Able to understand the study, willing to participate, and able to complete follow-up visits as scheduled
- No prior heart ablation or surgical procedures for atrial fibrillation
- No significant heart valve disease, blood clots in the heart, severely weakened heart function, or very enlarged left atrium
- No recent heart attack, unstable chest pain, or recent heart stent/bypass surgery (within 3 months)

Other trials that look related to this one.
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 two-step procedure for persistent atrial fibrillation that combines a heart ablation with isolation of a small heart pouch. It aims to see if this approach is more effective than standard care.
This study tests a new way to treat persistent atrial fibrillation using short bursts of electricity (pulsed fields) to carefully reset the heart's rhythm. It may help people whose irregular heartbeat has not improved with medication.
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 new type of ablation (pulsed-field) to treat persistent atrial fibrillation (AFib) that lasts more than 7 days. You may qualify if you have symptoms and haven't had other heart ablation procedures except for one specific type.
This study tests a new way to perform ablation (a type of heart procedure) for people with persistent atrial fibrillation (AF) that hasn't responded well to medication. The goal is to see if a targeted approach to the left atrium's back wall works better than standard ablation.
