Repeat procedures after second-generation cryoballoon ablation as an index procedure for persistent atrial fibrillation: one-year follow-up

摘要

Data indicate that the second-generation cryoballoon (Arctic Front Advance, Medtronic, Minnesota, USA) could be effective for persistent atrial fibrillation. However, electrophysiological findings and the midterm clinical outcome of repeat procedures following second-generation cryoballoon ablation are lacking.
