第二代冷冻球囊消融非瓣膜性阵发性心房颤动疗效分析
Efficacy analysis of second-generation cryoballoon ablation for non-valvular paroxysmal atrial fibrillation
摘要
Abstract
Objective To evaluate the safety and efficacy of the Medtronic second-generation cryoballoon ablation(CBA)in treating non-valvular paroxysmal atrial fibrillation(PAF).Methods Sixty-five patients with non-valvular PAF who had not previously undergone pulmonary vein isolation(PVI)were enrolled.All patients were treated by using the Medtronic second-generation cryoballoon ablation system.Baseline data,procedure-related parameters,and 12-month follow-up results were collected.Based on whether atrial fibrillation recurred,these patients were divided into a non-recurrence group and a recurrence group.General clinical data,immediate procedural success rate,intraoperative parameters,and procedure-related complications were compared between the two groups.Results All 65 patients successfully achieved circumferential PVI solely through CBA,with an immediate procedural success rate of 100％.The atrial fibrillation ablation success rate at 12-month follow-up was 90.8％.The mean procedure time was(98.68±19.13)min.The overall incidence of intraoperative and postoperative complications was 7.7％,with phrenic nerve injury occurring in 3.1％of cases.Conclusion Second-generation CBA demonstrates high safety and efficacy in treating non-valvular PAF,supporting its clinical utility for tailored therapeutic strategies.关键词
