Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
While there is a consensus to perform pulmonary vein isolation (PVI) as a cornerstone for the ablation of paroxysmal and persistent AF ablation, different additional ablation strategies are used to achieve a modification of the substrate that perpetuates the arrhythmia: linear lesions (anterior and roof lines) or ablation of complex fractionated atrial electrograms (CFAE). In the stepwise approach PVI, CFAE ablation and/or LL are combined according to the presenting arrhythmia during procedure.
The aim of the study is to determine whether there is a difference in terms of freedom from arrhythmia between a stepwise approach and a linear ablation for repeat procedure in patient with recurrence of persistent atrial fibrillation.
