Reports of incidental coronary artery abnormalities range from 0.6% to 1.3% during routine angiography, and 0.3% in autopsies. An isolated single coronary artery is a particularly rare congenital anomaly. Clinical presentation is usually nonspecific; patients with an isolated single coronary anomaly may present with symptoms such as angina, myocardial infarction or sudden cardiac death. The therapeutic options depend on origin, course and termination. It is dangerous and potentially lethal if a single coronary artery is associated with obstructive coronary artery disease. Two cases of anomalous origin of a coronary artery from a single Valsalva sinus without any other visible coronary artery detected by aortography are reported.
在常规血管造影术中,偶然发现的冠状动脉异常报告发生率为0.6%至1.3%,尸检中为0.3%。孤立的单支冠状动脉是一种极为罕见的先天性异常。临床表现通常不具特异性;孤立性单支冠状动脉异常的患者可能出现心绞痛、心肌梗死或心源性猝死等症状。治疗方案取决于其起源、走行和终止情况。如果单支冠状动脉与阻塞性冠状动脉疾病相关,则很危险且可能致命。本文报告了两例冠状动脉起源于单个主动脉窦且主动脉造影未检测到任何其他可见冠状动脉的病例。
