Are there pulmonary vein geometrical features associated with reconnection after pulsed field ablation of atrial fibrillation?

Background: Pulmonary vein (PV) isolation (PVI) using pulsed field ablation (PFA) is an emerging technique for the treatment of atrial fibrillation (AF). However, the recurrence rate of AF remains significant, and the durability of PVI is insufficient.

Objective: This study aimed to assess the impact of anatomical and geometrical features of the PV ostia on the PVI durability.
