摘　　要：肺静脉隔离是心房颤动导管消融的基础,目前主流术式是通过逐点射频消融策略实现肺静脉隔离,但由于传统消融模式只能实现40 W以下的安全输出,各点均需较长时间才能实现透壁毁损,不利于推广。近年来,随着消融设备的进步,可实现高功率(45-90 W)输出,大幅缩短手术时间,即高功率短时程消融,可以避免导管长时间操作及放电带来的一系列问题,在一定程度上可提高手术成功率。现从基础和临床研究两方面对高功率短时程消融的现状进行总结,并就其优势及局限性进行综述。Pulmonary vein isolation(PVI)is the cornerstone of atrial fibrillation catheter ablation,the current mainstream procedure is to achieve PVI through a point-by-point radiofrequency ablation strategy,but the traditional ablation mode can only achieve the safe output of below 40 W,it takes a long time for each point to accomplish transmural destruction,which is not conducive to promotion.Recently,with the improvement of ablation equipment,high power(45~90 W)output can be realized,and the operation time can be greatly shortened,that is,high-power short-duration(HPSD)ablation,which can avoid a series of problems caused by prolonged catheter operation and discharge,and improves the success rate of the procedure.This article summarizes the current research on HPSD ablation from basic and clinical studies and reviews its advantages and limitations.
