Safety and efficacy outcomes of protamine administration for heparin reversal following cryoballoon-based pulmonary vein isolation

摘要

Anticoagulation with heparin is required during catheter ablation of atrial fibrillation (AF) to reduce systemic thromboembolism. In this study, we aim to compare safety and efficacy outcomes between patients who receive protamine administration for reversal of heparin and those who do not, following cryoballoon-based pulmonary vein isolation (PVI) for AF.
