OP-128 Localization of Conduction Gaps Following Pulmonary Vein Isolation Using the Second Generation Cryoballoon




Objective


Conduction recovery characterizations after pulmonary vein isolation (PVI) using the first generation cryoballoon (CB) were already described. The aim of this study was to characterize the conduction recovery localization in case of recurrence after second generation CB – PVI.




Methods


Patients with recurrent atrial fibrillation (AF) after previous CB-PVI underwent repeat ablation. Pulmonary vein (PV) reisolation was performed by irrigated radiofrequency ablation using three dimensional (3-D) electroanatomic mapping. For analysis of the location of conduction gaps, the ipsilateral LA-PV junction was divided into four equally distributed quadrants.
