摘要

脉冲场消融(PFA)是一种用于心脏消融手术的非热能源。在脉冲场消融过程中,细胞通过电穿孔死亡:超快速(微秒至纳秒)电脉冲可破坏细胞膜的稳定性,造成不可逆的孔隙。PFA 可优先消融心肌细胞,而不损伤食道或膈神经等邻近组织。初步临床研究显示,接受肺静脉隔离术的心房颤动患者疗效高,安全性好。但问题是,这项新技术是否会在未来 5 年内取代射频电流或低温消融等知名的成熟热能源。

[Pulsed-field ablation-is it the only energy source for ablation in the future? : Pro/Contra].

Pulsed field ablation (PFA) is a nonthermal energy source used for cardiac ablation procedures. Cell death during PFA occurs via electroporation: ultrarapid (micro- to nanosecond) electrical pulses are applied to destabilize cell membranes causing irreversible pores. PFA leads to preferential ablation of myocardiocytes, sparing adjacent tissue like the esophagus or phrenic nerve. Preliminary clinical studies show high efficacy and a good safety profile in atrial fibrillation patients undergoing pulmonary vein isolation. The question remains, however, whether this new technology will replace well-known and established thermal energy sources like radiofrequency current or cryoablation within the next 5 years.
