A Curious Case of an Anomalous Right Coronary Artery

Michael Cinelli et al. Cardiol Res. 2022 Aug.

Abstract

Single coronary artery (SCA) is an unusual congenital anomaly, seen by diagnostic coronary angiography. Absence of the right coronary artery (RCA) is one of the rarest coronary artery anomalies occurring when the artery fails to develop in the right atrioventricular (AV) groove. Herein, we describe the case of a 58-year-old man presenting with new onset decompensated congestive heart failure found to have a congenitally absent right coronary ostium. The AV groove extended such that the left circumflex artery supplied the domain of the RCA. Such coronary artery anomalies are rare, and we aim to shed further insight into these congenital processes so that operators may remain vigilant of them in their practice.

Keywords: Coronary angiography; Coronary artery anomaly; Right coronary artery; Single coronary artery.
