Arrhythmias & electrophysiology
Four-year follow-up of outcomes of the hybrid epicardial-endocardial ablation: A single-center experience
Authors' conclusion
The hybrid convergent procedure reduces AF recurrence and the need for antiarrhythmic drugs and, while maintaining a good safety profile, for the treatment of persistent and long-standing persistent AF.
