Long-term Outcome Following Concomitant Surgical Ablation for Atrial Fibrillation at University Hospital Basel: A Retrospective Study

Completed

• Conditions: Atrial Fibrillation; Maze Procedure

• Registration Number: NCT05542017
• Lead Sponsor: University Hospital, Basel, Switzerland

Brief Summary

This retrospective single-centre study aims to examine the success rate of concomitant surgical ablation in patients with atrial fibrillation (AF) with an up to eight years follow-up period. Moreover, the focus of this study was to identify variables which predict freedom from AF, such as the type of AF, lesion set performed, energy source used and the patient's characteristics.
