Variations in the origin of the right coronary artery have an incidence between 0.09 % and 0.92 %. Herein, we report a rare case of a coronary artery anomaly in which the right coronary artery originates from the left main coronary artery. This variant was found during routine coronarography, combined with an artificial aortic valve. Despite their rare occurrence, some variations in the origins of the coronary arteries can be life threatening and are associated with a higher risk of sudden cardiac death. They can also pose serious technical challenges and predispose to complications during coronary angiographic procedures. Thus, knowledge of such anomalies is paramount for managing the patients correctly.

KEY WORDS: Right coronary artery; Anatomical variation; Coronarography; Angiogram.
