Coronary artery anomalies are rare congenital variants of coronary artery anatomy accounting second most common cause of sudden cardiac death in young competitive athletes. A single ostium coronary artery anomalous is an extremely rare variant with an incidence of less than 0.004%. They may present as chest pain, arrhythmia, or sudden death. Recently, advanced imaging techniques such as computed tomography and magnetic resonance imaging coronary angiography are becoming the alternatives investigation for diagnosis. We reported a rare case of 50 years old lady who presented with acute chest pain with normal electrocardiography, echocardiography, and cardiac markers. Coronary Computed tomography angiography revealed anomalous coronary artery anatomy with both right and left coronary artery arising from the large common trunk of the right coronary cusp, left main coronary artery having trans-septal course, there was no flow-limiting coronary artery disease. She was medically managed with a single antiplatelet, beta-blocker, and statin therapy.
冠状动脉异常是冠状动脉解剖的罕见先天性变异，是年轻竞技运动员心脏性猝死的第二大常见原因。单一开口冠状动脉异常是一种极为罕见的变异，发病率低于 0.004%。它们可能表现为胸痛、心律失常或猝死。最近，计算机断层扫描和磁共振成像冠状动脉造影等先进的成像技术正成为诊断的替代研究方法。我们报告了一例罕见的 50 岁女性病例，她表现为急性胸痛，心电图、超声心动图和心脏标志物正常。冠状动脉计算机断层血管造影显示异常的冠状动脉解剖结构，右冠状动脉瓣的大共同干发出左右冠状动脉，左主干冠状动脉有穿隔行程，没有限制血流的冠状动脉疾病。她接受了单一抗血小板、β受体阻滞剂和他汀类药物治疗。
