Single coronary artery is a rare anomaly, with a reported incidence of 0.024%. It can be diagnosed on coronary computed tomography angiography, where the presence of ostial narrowing and compression between the great vessels must be carefully excluded, since these malignant forms can lead to sudden cardiac death and other ischemic complications. We describe a case of single coronary artery arising from the right sinus of Valsalva presenting with symptoms of ischemic chest pain.
单支冠状动脉是一种罕见的异常情况,报告发病率为0.024%。它可在冠状动脉计算机断层血管造影上被诊断出来,在此过程中,必须仔细排除大血管之间存在的开口狭窄和受压情况,因为这些恶性形式可导致心源性猝死和其他缺血性并发症。我们描述了一例起源于瓦尔萨尔瓦右窦的单支冠状动脉病例,该病例表现为缺血性胸痛症状。
