Impact of 3D mapping on procedural characteristics and outcomes in cryoballoon pulmonary vein isolation for atrial fibrillation

Purpose The use of 3D mapping during cryoballoon pulmonary vein isolation (PVI) is optional with added cost but potential benefit in aiding vein identification, reducing fluoroscopy, and post-ablation testing. Data are limited evaluating procedural characteristics and outcomes in patients undergoing cryoballoon PVI with mapping vs. no mapping. In the present study, we compare procedural characteristics and recurrence-free rates in patients undergoing cryoballoon PVI among patients using CARTO®, NavX™, or no mapping system.
