This article reviews and compares the rationale and evidence supporting high-power, short-duration radiofrequency (RF) ablation with those of conventional-power, conventional-duration RF ablation for atrial fibrillation (AF). The pros and cons of each approach, biophysics of ablation, pre-clinical studies informing clinical utilization, and the accumulated clinical evidence are presented. Both conventional-power, conventional-duration RF ablation and high-power, short-duration ablation are similarly safe, and effective approaches for AF ablation. Theoretical advantages of high-power, short-duration ablation, including greater procedure efficiency and limited conductive heating of collateral structures, must be weighed against the narrower safety margin related to rapid energy delivery during high power ablation.

房颤的高功率、短时消融:利弊

本文回顾并比较了支持高功率、短时射频 (RF) 消融与常规功率、常规持续时间射频消融治疗心房颤动 (AF) 的基本原理和证据。介绍了每种方法的优缺点、消融的生物物理学、告知临床应用的临床前研究以及积累的临床证据。常规功率、常规持续时间 RF 消融和高功率、短持续时间消融对于 AF 消融同样安全有效。高功率、短时间消融的理论优势,包括更高的手术效率和有限的侧支结构传导加热,必须与高功率消融期间与快速能量输送相关的较窄安全裕度进行权衡。
