BACKGROUND: The aim of this study was to assess the overall incidence of complications in a large sample of consecutive @entity1 having undergone pulmonary vein (PV) isolation, evaluating also the rate of complications in radiofrequency (RF) and cryoballoon (CB) ablation technologies. METHODS AND RESULTS: From January 2008 to December 2014, 1352 consecutive PV isolation procedures were performed in our center; a total amount of 1233 AF ablation procedures fulfilling inclusion criteria was finally taken into consideration for our analysis. A total of 642 procedures were performed using RF ablation technology and 591 using CB system. Serious adverse events occurred in 36 procedures (2.9%): specifically, vascular complications in 14 (1.1%); @entity2293 in 13 (1.0%); a @entity1031 event in 4 (0.3%); and @entity1727 , PV intramural @entity1410 , retroperitoneal @entity1410 , @entity1410 and persisting @entity129 all occurred in 1 @entity1 individually (0.1%). No deaths related to the procedure occurred. The complication rate did not significantly differ in the RF and CB groups (respectively, 3.6% vs 2.2%; p=0.1). Complication rates considerably decreased over the study period from 4.67% in 2008 to 1.55% in 2014. Interestingly, each 1-point increase in the CHA2DS2-VASc score was found to increase by 51% the likelihood of a serious adverse event. CONCLUSIONS: The incidence of serious adverse events following AF ablation procedures was 2.9%. @entity455 were the most frequent complication followed by tamponade and @entity1031 events. The rate of complications considerably decreased over time. CHA2DS2-VASc score was found to be associated with higher risk of complications.
