心房颤动冷冻球囊消融术常见并发症及其防治

Common Complications of Cryoballoon Ablation of Atrial Fibrillation and Its Prevention and Treatment

对于药物控制不佳的症状性心房颤动患者,导管消融已经成为一线治疗方案。冷冻球囊消融术作为心房颤动治疗的新技术,在临床上越来越多地得到应用。通常,在单次冷冻后就可以取得满意的肺静脉电隔离效果,相对于传统的基于逐点消融的射频消融术有着巨大优势。但冷冻球囊消融术投入临床使用时间较短,目前仍有一些并发症存在。现总结其常见并发症的发生机制及防治措施。

Catheter ablation has become the first-line treatment for patients with symptomatic atrial fibrillation who are poorly controlled with drugs.As a new technique for the treatment of atrial fibrillation,cryoballon ablation has been applied more and more in clinic.In general,pulmonary vein isolation can be achieved after a single cryopreservation,which has advantages over traditional point-by-point ablation-based radiofrequency ablation.However,the clinical application of cryoballon ablation is short,and there are still some complications.This article summarized the mechanism and prevention and treatment measures of its common complications.
