English abstract
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 Depart ment 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 ostium with the right coron ary artery from the right coronary sinus. To the best of the authors' knowledge, this type of variant has not been prev iously reported in the literature.
