Pulmonary Vein Isolation Using a Second‐Generation Cryoballoon Catheter: A Randomized Comparison of Ablation Duration and Method of Deflation

Abstract

A single application with the second-generation cryoballoon catheter results in a high rate of PV isolation. The degree of vascular injury was not increased by active balloon deflation and no differences in acute efficacy or mature transmural circumferential lesions were observed with 2- versus 4-minute applications.
