摘要

脉冲场消融利用不可逆电穿孔破坏细胞膜,诱导心肌细胞凋亡。可逆电穿孔已用于其他专业,但其在心脏消融术中的应用尚不清楚。本文中,一名69岁女性因非典型心房扑动接受反复消融,在心脏手术(包括MAZE)和既往消融后出现广泛疤痕,导致宏观再入回路。为了减少多余的病变和进一步的心律失常,我们使用单脉冲确认峡部位置,心律失常停止。作为结论,可逆电穿孔可用于在不可逆病变产生之前测试感兴趣的区域。

Using a Novel Pulsed Field Ablation Technique to Identify the Critical Isthmus Within a Tachycardia Circuit.

Pulsed field ablation uses irreversible electroporation to interrupt cellular membranes and induce myocyte apoptosis. Reversible electroporation has been used in other specialties, but its utility in cardiac ablation is unknown. Here, a 69-year-old woman undergoing repeat ablation for atypical atrial flutter presented with extensive scar after cardiac surgery (including MAZE) and previous ablation, leading to a macro re-entry circuit. To minimize superfluous lesions and further arrhythmia, we used a single pulse confirming the isthmus location, with cessation of the arrhythmia. As a conclusion, reversible electroporation may be used to test areas of interest prior to irreversible lesion creation.
