[Congenital anomalies of the origin and/or distribution of coronary arteries originating from the aorta. Angiographic study of 39 cases].

39 cases of congenital anomalies in the origin and/or in the distribution of the coronary arteries arisen from the aorta, without associated cardiac abnormality, seen in the course of 6 525 selective coronary arteriographies in adults, are reported and integrated into a general classification of coronary arteries abnormalities. The clinical correlation of these anomalies is specified. The authors emphasize the importance of their diagnosis in the surgery of valve replacement or of myocardial revascularization.
