Unusual Association of Three Types of Congenital Coronary Artery Diseases.

Congenital coronary artery disease (CAD) is commonly asymptomatic and often benign. Investigation of potential myocardial ischemia is also necessary. We report an original observation of abnormal origin and course of the right coronary artery (RCA), abnormal left main artery, and agenesis of the left anterior descending (LAD) artery. This is the first report of an association of 3 types of congenital coronary artery anomaly according to the modified Angelini's classification. This high-risk condition was successfully treated surgically.
