Congenital anomalies of the coronary arteries. Classification and significance.

Abstract

An understanding of the anomalies of the coronary arteries is imperative for physicians dealing with diagnosis and treatment of coronary artery disease. Although not as common as acquired coronary artery disease, congenital coronary anomalies contribute to significant morbidity and mortality. In addition, they may present difficulties for the angiographer at the time of catheterization, as well as a challenge for the radiologist in interpretation. To facilitate a better understanding of these anomalies, a new classification is presented, together with illustrations and discussion of the clinical significance.
