Anomalous Aortic Origin of Coronary Arteries from the Opposite Sinus: A Case Report

Abstract

Anomalous aortic origin of coronary arteries from the opposite sinus (AAOCA) is a rare finding which, when discovered, raises questions regarding its approach and management. Modern imaging techniques can help us to identify certain anatomical features of the anomalous coronary arteries to further classify them as benign or malignant anomalies. We present a case of a 64-year-old male who had an incidental finding of AAOCA with the left anterior descending artery arising from the right coronary cusp from an ostium anterior to the one that gave rise to both the left circumflex artery and right coronary artery (RCA). The patient was managed with a percutaneous coronary intervention for an obstructive disease of the RCA and was discharged with regular follow-ups.

Anomalous aortic origin of the left coronary artery: A rare case of an origin from the noncoronary sinus

“…0.3%). 2,3 The most common AOLCA refers to the left coronary artery that originates from the right coronary sinus, and it is even more rare for AOLCA to originate from the noncoronary sinus at the level of the sinotubular junction, which is presented in this case. AAOCA is one of the main causes of sudden cardiac death in young athletes.…”

“…An anomalous aortic origin of a coronary artery (AAOCA) refers to a congenital abnormality of the origin and/or course of a coronary artery that arises from the aorta, which is a rare congenital disease with an incidence of approximately 0.6%-1.3%. 1,2 However, the most common type is anomalous origin of the right coronary artery (AORCA), which has an incidence that is approximately three times higher than that of the anomalous origin of the left coronary artery (AOLCA) (approximately F I G U R E 3 Intraoperative findings: the ostium of the LCA (white star) is located in the NSV near the left/noncoronary commissure (A). Because of the narrow ostium, it needs to be cut with a sharp scalpel to be able to pass through the thinnest coronary bougie (B).…”
