Long-term efficacy and health consumption before and after ablation of AF

Abstract Background Atrial fibrillation (AF), the most common arrhythmia worldwide, is associated with increased morbidity and mortality. Catheter ablation of AF effective treatment option for symptomatic patients. The long-term efficacy however not very well studied nor health consumption before after an atrial fibrillation. Purpose To study in 1453 consecutive patients undergoing our institution. Methods Consecutive radiofrequency were included prospectively. 4 mm irrigated (Biosense Webster) catheters Carto® used all procedures. After a mean period years survey measuring symptoms was sent out to who treated between 1st January 2010 31st December 2016. Data collected from local registries, national registry catheter ablations registry. Health measured as in-hospital visits two procedure assessed. Results 877 (72.7%) had no further four procedure. Among 329 still reported 237 (72%) milder, 65 (20%) unchanged 20 (8%, 1.3% total) worsened e ablation. total number 2 4067. There 2594 1473 ablation, decrease by 43%. majority these related, 2264 908, respectively, 60%. Seven stroke five after. median length stay 1 day both Conclusion significantly decreased AF. effect good freedom approximately 70% years.
