BACKGROUND 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. METHODS AND RESULTS Eighty-nine consecutive atrial fibrillation patients… Expand

Two randomized, prospective, multicenter studies confirmed no difference in 1‐year efficacy between point‐by‐point radiofrequency (RF) and cryoballoon (CB) ablation for pulmonary vein isolation (PVI) in patients with paroxysmal atrial fibrillation (AF) and two retrospective studies demonstrated equivalence in clinical outcomes.

Evaluated the effectiveness of PVI performed by contact force–guided radiofrequency (CF‐RF) versus second‐generation cryoballoon‐based ablation in patients with LCPV. Expand


Second-generation cryoballoon ablation in the setting of left common pulmonary veins: Procedural findings and clinical outcome.
CB-A ablation in LCPV+ patients is effective and showed no difference in clinical outcome compared to LCPVs, and electrical isolation could be achieved in all left-sided veins. Expand

Pulmonary vein ostium shape and orientation evaluated by MSCT proved to be useful in predicting the degree of occlusion obtained during CA. Expand
Association between pulmonary vein orientation and atrial fibrillation-free survival in patients undergoing endoscopic laser balloon ablation.
PV orientation assessment may be useful for selecting the most suitable patients for EAS PVI, and is associated with AF-free survival after EAS Fibrillation PVI. Expand
Pulmonary venous isolation by antral ablation with a large cryoballoon for treatment of paroxysmal and persistent atrial fibrillation: medium-term outcomes and non-randomised comparison with pulmonary venous isolation by radiofrequency ablation
PVI isolation can be achieved in less than 2 h by a simple cryoablation protocol with excellent results after a single intervention, particularly for paroxysmal AF. Expand

In this multicenter experience, PNI was a rare complication (0.48%) of AF ablation and complete or partial recovery was observed in the majority, and ablation of the right superior PV, SVC, and left atrial appendage were associated with PNI. Expand
Clinical assessment of cryoballoon ablation in cases with atrial fibrillation and a left common pulmonary vein
