Pulmonary vein isolation cryoablation for patients with persistent and long-standing persistent atrial fibrillation: Clinical outcomes from the real-world multicenter observational project

In this multicenter evaluation of cryoballoon ablation, the PVI procedure was safe, effective, and efficient with regard to the treatment of patients with persistent and long-standing persistent AF. The reasonable mid-term success rates agree with current clinical studies that establish PVI as a cornerstone index ablation strategy.
