Incidence and characteristics of complications in the setting of second-generation cryoballoon ablation: A large single-center study of 500 consecutive patients

The present findings highlight that PV isolation using CB-A technology can be safely performed with a low incidence of adverse events. The incidence of major complications after atrial fibrillation ablation procedures using CB-A technology was 2% in our study. The most frequent complication consisted of vascular complications at the puncture site. No deaths related to the procedure occurred.
