Reconduction patterns after cryoballoon ablation may guide redo targets in recurrent AF; hypothesis-generating for durability-focused techniques.
What is the rate and anatomical distribution of pulmonary vein reconduction in patients with atrial tachyarrhythmia recurrences after second-generation cryoballoon ablation?
Second-generation cryoballoon ablation is associated with a high rate of persistent pulmonary vein isolation (69% of PVs), with the right inferior PV being a predilection site for reconduction in patients with recurrent arrhythmias.
