Comparative StudyPulmonary vein isolation in patients with a left common pulmonary vein: Comparison between second-generation cryoballoon and radiofrequency ablation.
Adaptability of cryoballoons to anatomic pulmonary vein (PV) variations is limited due to the fixed geometrical shape, and use for left common PVs (LCPVs) is controversial. We compared the procedural and clinical outcomes in patients with LCPVs after cryoballoon and radiofrequency ablation, and explored the morphological parameters associated with procedural difficulty in LCPV isolations using cryoballoons. ⋯ Cryoballoon ablation was similarly as effective as radiofrequency ablation in patients with LCPVs, and morphological evaluations aided in predicting procedural difficulty in LCPV isolations.
