Abstract

The incidence of lesions involving the left main coronary artery (LMCA) during coronary angiography is approximately 5% to 8%. It usually presents with acute coronary syndrome and can be fatal. Total occlusion of the LMCA is rare, often accompanied by myocardial infarction and cardiogenic shock. We present an LMCA chronic total occlusion case in a 60-year-old female patient with chronic coronary syndrome. In our case, the LMCA was selectively visualized, and it was found to be occluded. The right coronary artery fed the entire left system through the collateral network. The patient had no risk of coronary artery disease other than hypertension. Successful coronary artery bypass grafting was performed without any complications.

摘要

在冠状动脉造影期间，累及左主冠状动脉（LMCA）的病变发生率约为5％至8％。它通常表现为急性冠状动脉综合征，可能是致命的。LMCA的完全闭塞是罕见的，常伴有心肌梗死和心源性休克。我们介绍了一名60岁女性慢性冠状动脉综合征患者的LMCA慢性完全闭塞病例。在我们的案例中,LMCA被选择性地可视化，发现它被遮挡了。右冠状动脉通过侧支网络供给整个左系统。该患者除高血压外没有冠状动脉疾病的风险。成功进行了冠状动脉旁路移植术，没有任何并发症。
