BACKGROUND Pulmonary vein (PV) isolation (PVI) remains the cornerstone of catheter ablation (CA) in persistent atrial fibrillation (AF) (PeAF), although less successful than for paroxysmal AF. Whether rapid or fibrillatory (PV AF) PV firing may identify patients with PeAF more likely to benefit from a PV-based ablation approach is unclear. OBJECTIVE The purpose of this study was to determine the relationship between the PV cycle length (PVCL) and the PV AF outcome after CA. METHODS Before… CONTINUE READING
