| 其它 | Brief Summary Cryoballoon pulmonary vein isolation (PVI) has emerged as an alternative to radiofrequency in the treatment of drug-resistant atrial fibrillation (AF). (1) Cryoablation offers potential advantages over radiofrequency, including shorter procedure times, decreased fluoroscopy time, shorter hospital length of stay, and different rates and types of complications. (2) The efficacy over a mean follow-up of one year with cryoablation for AF is comparable to that of radiofrequency ablation in a prospective randomized trial, with a lower major complication rate (3, 4). In recent years, AF cryoablation has established itself as a real alternative to RF ablation, to the point that this ablative source is chosen in one out of five European patients undergoing PV isolation. 70-80% of patients maintain sinus rhythm after a first procedure, showing an efficacy rate equivalent to ablation by RF. |
