Congenital anomalies of coronary arteries are rare diseases, often diagnosed randomly during selective coronarography. They occur in approximately 1% of the adult patient population undergoing coronarography from another indication. They are divided into anomalies of origin, course or termination. These congenital anomalies may be clinically silent or present with various symptoms such as angina pectoris, ventricular ar- rhythmia, syncope or sudden cardiac death.^1,2 The article describes a case report of a 56-year-old man with anomalous origin of left anterior descending artery (LAD), manifested by exertional stenocardia. Selective coronarography showed smooth coronary artery contours, without atherosclerosis, the secondary finding was the LAD originating from right coronary artery, the ramus circumflexus and the ramus diagonalis originating from the left coronary artery and had a normal course. Supplemented CT coronarography subsequently showed LAD with an interarterial course between the aorta and pulmonary artery and an intramural course of the anomalous artery.
