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

The impact of left common pulmonary vein on cryoballoon ablation of atrial fibrillation. A meta-analysis
TLDR
The presence of LCPV does not affect the long-term outcome of paroxysmal and persistent atrial fibrillation ablation with 28 mm CB-A compared to normal left PVs pattern. Expand

TLDR
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.

TLDR
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

TLDR
Comparable results with regard to clinical success and durability of PVI were shown when comparing patients of the LCPV group and the control group, and a high acute success rate was shown. Expand

TLDR
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.
TLDR
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

TLDR
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

TLDR
Eccentricity index measured from pre-procedural CT/MR imaging can predict difficulty of PV isolation and PN injury during cryoballoon ablation for paroxysmal AF. Expand

TLDR
Pulmonary vein isolation with the 2nd generation cryoballoon appears to be an effective treatment for symptomatic atrial fibrillation also in patients over 75 years of age. Expand

TLDR
The ostial PV anatomy seems to have an important impact on clinical outcome and should be considered when planning and performing cryoballoon AF ablation procedures. Expand

TLDR
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
