Combined Endoscopic Epicardial and Percutaneous Endocardial Ablation Versus Repeated Catheter Ablation in Persistent and Longstanding Persistent Atrial Fibrillation

Not Applicable

Completed

• Conditions: Persistent and Longstanding Persistent Atrial Fibrillation; Atrial Fibrillation

• Registration Number: NCT02695277
• Lead Sponsor: AtriCure, Inc.

Brief Summary

This is a prospective, randomized (2:1) multicenter trial to investigate the optimal treatment of Persistent and Longstanding Persistent AF referred for Radiofrequency (RF) ablation.The study objective is to compare the efficacy and safety of two interventional approaches, in preventing the recurrence of AF in symptomatic, drug refractory patients with persistent or longstanding persistent atrial fibrillation.
