An extremely rare congenital abnormality is reported in which the anterior descending branch of the left main coronary artery arises independently from the pulmonary trunk in a young patient who presented with unstable angina. Its clinical presentation, angiographic identification and surgical treatment are described. It appears to be a distinct entity with few of the features of the classical form of anomalous origin of the left main coronary artery.
报道了一种极为罕见的先天性异常情况，即一名出现不稳定型心绞痛的年轻患者，其左冠状动脉前降支独立起源于肺动脉干。文中描述了其临床表现、血管造影识别及外科治疗情况。它似乎是一种独特的实体，几乎没有典型的左冠状动脉异常起源形式的特征。
