Abstract

The coronary arteries are also subject to congenital anomalies of both minor and major consequence. Hemodynamically significant primary anomalies of the coronary arteries are those which alter myocardial perfusion. There are four major types : coronary artery fistula, origin of the left voronary artery from the pulmonary artery, congenital coronary stenosis or atresia and origin of the left or right coronary artery from the opposite sinus of Valsalva with subsequent passage of the vessel between the aorta and right ventricular infundibulum. Minor anomlies are the variation of the origin of the coronary arteries from the aorta with normal distal circulation. We can see more coronary anomalies associated with congenital cardiac anomalies, probably representing a circulatory response to the primary intracardiac defect. We present a total of 76 cases of congenital coronary anomalies, reviewing 3946 cases of angiocardiography or selective coronary arteriography, performed during last 8 years at Sejong General Hospital.
