Ablation plan guided by left-heart scar map for persistent atrial fibrillation
Part of Heart & circulation clinical trials.
This study tests whether using a 3D heart “scar map” helps doctors choose a better catheter ablation strategy for people with persistent atrial fibrillation (AF). It may help reduce ongoing AF by targeting the scar area in the left atrium.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 19 years old or older.
- You have symptomatic persistent atrial fibrillation and need catheter ablation because symptoms continue despite anti-arrhythmia medicines, or because your scar area meets specific scan thresholds.
- Your doctors can create a high-quality 3D electrical map during the procedure so your scar (LVA) burden can be measured.
- You can safely take blood thinners (heparin during the procedure and/or oral anticoagulation).
- You do NOT have certain heart and health limits (examples: very enlarged left atrium size, prior AF ablation/surgery, a heart blood clot, very weak heart pumping, major valve disease, or recent stroke/heart attack).

This trial tests a new type of catheter ablation (using heat to create scar lines in the heart) for people with persistent atrial fibrillation who have a higher risk of stroke or bleeding. It aims to see if this approach can help prevent strokes and reduce the need for long-term blood thinners.
This study tests whether an AI software can help doctors identify which people with persistent atrial fibrillation might need more than just a standard ablation procedure. The software analyzes heart signals during the ablation to guide treatment, potentially improving outcomes for people whose condition is more complex.
This trial tests a new catheter system to treat atrial fibrillation (AF) by creating small scars in the heart to block faulty signals. It may help people with symptoms that continue despite medication and who are scheduled for a standard ablation procedure.
This study compares two techniques for treating persistent atrial fibrillation: one uses standard anatomy-based ablation, and the other uses a special mapping system to guide the procedure. It aims to find which method works better for people who have not had prior ablation.
This trial tests whether a “virtual” computer map created from your heart scans can help doctors do catheter ablation to treat atrial fibrillation (AF). It aims to improve the procedure for people whose AF symptoms were not controlled well with anti-arrhythmia medicines.
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.
