Is the time of atrial fibrillation recurrence after cryoballoon ablation of paroxysmal atrial fibrillation influenced by the pattern of PV reconnections?

ConclusionsAt redo ablation, most patients with recurrence of AF after CB PVI had PV reconnection(s). Patients with PV reconnection(s) showed a negative correlation between the number of reconnected PVs and the time of AF recurrence with more extensive PV reconnections resulting in earlier PV recurrences after the blanking period. Patients without PV reconnection experienced early AF recurrences, indicating non-PV triggers contributing for paroxysmal AF recurrences in these patients.
