Abstract

Radiofrequency ablation (RFA) is a commonly performed procedure for symptomatic atrial fibrillation (AF). Herein, we describe a case of transient ST elevation during the isolation of right-sided pulmonary veins. The patient was hemodynamically stable and due to the transient nature of ST-elevation, the procedure was completed successfully. Subsequently, the cardiac catheterization was performed which did not reveal any significant obstructive coronary lesion or a thrombus. In this report, we attempt to explain possible mechanisms for ST-elevation during RFA of AF.

摘要

射频消融术(RFA)是治疗症状性心房颤动(AF)的常用方法。在此,我们描述一例在右侧肺静脉隔离过程中出现短暂性ST段抬高的病例。患者血流动力学稳定,由于ST段抬高具有短暂性,手术得以成功完成。随后进行了心导管检查,未发现任何明显的阻塞性冠状动脉病变或血栓。在本报告中,我们试图解释房颤射频消融术中ST段抬高的可能机制。
