Catheter ablation has been shown to be more effective than medications for controlling symptoms and reducing the risk of these complications; however, recurrence of AF after ablation remains a significant challenge, often due to incomplete or ineffective initial procedures. This clinical trial aims to determine whether a novel, patient-tailored ablation strategy can improve outcomes compared to the current standard-of-care approach. Participants will be randomly assigned to undergo either standard pulmonary vein isolation or a more individualized ablation procedure that identifies and targets patient-specific sources of AF. All participants will undergo the ablation procedure, receive continuous heart rhythm monitoring, and be followed over time to assess recurrence and safety outcomes.",[106,107,108],"Atrial Fibrillation","Catheter Ablation","Radiofrequency Catheter Ablation","2026-04-23",{"date":111,"type":112},"2026-04-29","ACTUAL",{"date":114,"type":112},"2026-03-23",{"date":116,"type":100},"2030-03",{"name":5,"class":6},2]
