Ablation of Complex Fractionated Electrograms With or Without Additional Linear Lesions for Persistent Atrial Fibrillation

Not Applicable

Completed

• Conditions: Atrial Fibrillation; Recurrence
• Interventions: Procedure: PVI+CFAE+DCC; Procedure: PVI, CFAE, anterior and roof line, DCC

• Registration Number: NCT02059369
• Lead Sponsor: Deutsches Herzzentrum Muenchen

Brief Summary

While there is a consensus to perform pulmonary vein isolation (PVI) as a cornerstone for paroxysmal and persistent atrial fibrillation (AF), different additional ablation approaches are used for substrate modification: linear lesions, ablation of complex fractionated atrial electrograms (CFAE) or a combination of both. The aim of this study is to determine whether there is a difference in terms of freedom from arrhythmia recurrence between PVI with CFAE ablation in combination or not with linear lesions in patients with persistent AF.
