Differential Gap Location after Radiofrequency versus Cryoballoon Pulmonary Vein Isolation: Insights from a Randomized Trial with Protocol-Mandated Repeat Procedure.

Although RF and CRYO produce similar proportions of durably isolated PVs, gap locations appear to develop in procedure-specific patterns. After RF, ipsilateral PV reconduction is more frequent and gap sites cluster by the carina, suggesting that this region should be selectively ablated for more durable PVI.
