Two versus one repeat freeze-thaw cycle(s) after cryoballoon pulmonary vein isolation: the alster extra pilot study.

abstract：BACKGROUND:Stroke risk is a significant concern in patients with atrial fibrillation (AF). Low stroke risk patients (CHADS2 VASc 0-2) are often treated long-term with aspirin after catheter ablation. Defining the long-term risks versus benefits of aspirin therapy, after an ablation, is essential to validate this common...
