A case of asymptomatic acute coronary occlusion secondary to radiofrequency catheter ablation of a left lateral accessory pathway is reported. Due to post-procedural ST modifications of the surface ECG, a coronary angiography was performed which disclosed total occlusion of the first marginal branch of the left circumflex coronary artery. Acute myocardial infarction was confirmed by moderate cardiac enzyme release, abnormal myocardial perfusion scan and mild lateral hypokinesia at echocardiography. This rare but potentially harmful complication of interventional electrophysiology should be kept in mind and coronary angiography performed immediately when coronary occlusion related to radiofrequency application is suspected.
报告了一例因左侧旁路途径射频导管消融继发无症状性急性冠状动脉闭塞的病例。由于术后体表心电图ST段改变，进行了冠状动脉造影，结果显示左旋支冠状动脉第一钝缘支完全闭塞。通过适度的心肌酶释放、异常的心肌灌注扫描以及超声心动图显示的轻度侧壁运动减弱，证实了急性心肌梗死。这种介入性电生理罕见但潜在有害的并发症应予以重视，当怀疑与射频应用相关的冠状动脉闭塞时，应立即进行冠状动脉造影。
