The objective of the study was to investigate whether early pulmonary vein reconnection (PVR) is a predictor of late arrhythmia recurrence after a single ablation procedure for paroxysmal atrial fibrillation (AF). Further ablation was delivered to patients with acute PVR to test whether this strategy could reduce recurrences. ⋯ In patients with paroxysmal AF undergoing a single ablation procedure, PVR 30 min after the initial PVI is associated with late AF recurrence. However, the strategy of 30 min waiting and reablating does not appear to be superior to immediate termination of the procedure after initial PVI.
