What is the efficacy and safety of catheter ablation for atrial fibrillation in worldwide practice?
A worldwide survey demonstrates that catheter ablation for atrial fibrillation is highly effective, achieving success in about 80% of patients and allowing 70% to remain off antiarrhythmic drugs.
Supports real-world AF ablation benchmarks; leaves open need for RCTs to confirm durability and guide selection.
When analyzed in a large number of electrophysiology laboratories worldwide, catheter ablation of AF shows to be effective in approximately 80% of patients after 1.3 procedures per patient, with approximately 70% of them not requiring further antiarrhythmic drugs during intermediate follow-up.
