A dual left anterior descending (LAD) artery is a rare congenital anomaly which is classified into different types based on the origin, course and termination of the short and long LAD arteries. To date, 10 variants of dual LAD artery anomalies have been described. We report a 44-year-old woman who was referred to the Department of Radiology, Royal Hospital, Muscat, Oman, in 2017. Coronary computed tomography angiography revealed a dual LAD artery anomaly in which the short and long LAD arteries shared a common with the right coronary artery from the right coronary sinus. To the best of the authors' knowledge, this type of variant has not been previously reported in the literature.
双左前降支（LAD）动脉是一种罕见的先天性异常，根据短LAD动脉和长LAD动脉的起源、走行和终末情况可分为不同类型。迄今为止，已描述了10种双LAD动脉异常的变体。我们报告一名44岁女性，她于2017年被转诊至阿曼马斯喀特皇家医院放射科。冠状动脉计算机断层扫描血管造影显示双LAD动脉异常，其中短LAD动脉和长LAD动脉从右冠状动脉窦起与右冠状动脉共用一个共同开口。据作者所知，这种类型的变体此前在文献中尚未有报道。
