A single coronary artery (SCA) is a rare congenital anomaly that can be incidentally found as a part of ischemic heart disease or angina workup. A modified Lipton classification is used to categorize the disease. The majority of diseases do not need surgical correction, with the exception of a few conditions. This report presented the case of a 49-year-old man who presented with stable angina with a single coronary artery arising from the right coronary sinus with an intraseptal course of the left main coronary artery. This is categorized as RII-S in the modified Lipton classification and is considered a high-risk anomaly. He underwent an unroofing procedure to decompress the left coronary artery with a resolution of symptoms.
单支冠状动脉（SCA）是一种罕见的先天性异常，可在缺血性心脏病或心绞痛检查中偶然发现。采用改良的利普顿分类法对该病进行分类。大多数病例无需手术矫正，少数情况除外。本报告介绍了一名49岁男性患者，该患者表现为稳定型心绞痛，其单支冠状动脉起源于右冠状动脉窦，左主冠状动脉走行于室间隔内。在改良的利普顿分类中，此病例归类为RII-S型，被认为是高危异常。他接受了开窗手术以解除左冠状动脉受压，症状得以缓解。
