Anomalous Origin of Right Coronary Artery from the Left Anterior Descending Artery: A Case Report

Abstract

Background and Aim: Anomalous origin of the right coronary artery from the left anterior descending artery is extremely rare. It is usually asymptomatic but can be associated with a risk of myocardial ischemia and sudden death. Case presentation: This paper presents the case of an elderly male with exertional dyspnea. He underwent diagnostic measures including coronary artery angiography which showed severe stenotic three-vessel disease and right coronary artery anomaly. He underwent coronary artery bypass grafting and discharge home in good condition. Conclusion: Although the abnormal origin of the right coronary artery from the left anterior descending artery is a rare anomaly, due to causing chest pain and the possibility of sudden death, it is considered important. For a definite diagnosis of this anomaly coronary angiography is useful.
