Abstract

Coronary artery aneurysms are uncommon and are usually described as dilatations larger than 1.5 times the diameter of the adjacent coronary arteries. The aneurysms vary between 0.15% and 4.9% and usually affect the right coronary artery, followed by the circumflex and anterior descending artery. Left main coronary artery (LMCA) aneurysm is an extremely rare clinical entity. Herein, we present a case in a 69-year-old man with a prior history of chest pain and palpitations. Significant ischemic ST changes were registered on Holter electrocardiography during paroxysmal atrial fibrillation.

摘要

冠状动脉瘤并不常见，通常被描述为直径大于相邻冠状动脉直径1.5倍的扩张。动脉瘤的发生率在0.15%至4.9%之间，通常累及右冠状动脉，其次是回旋支和前降支动脉。左冠状动脉主干（LMCA）动脉瘤是一种极其罕见的临床情况。在此，我们报告一例69岁男性病例，该患者既往有胸痛和心悸病史。动态心电图监测显示，在阵发性心房颤动期间出现明显的缺血性ST段改变。
