Introduction:Catheter ablation (CA) is superior to medical therapy in the management of atrial fibrillation (AF). The median follow-up duration for the patient population was 1168 days post-ablation. Catheter ablation was presumed successful in 19/32 patients who experienced a CVA. Conclusions:CVA occurred in 1.4%
