A Sole Left Coronary Artery

Abstract

Coronary artery anomalies are defined as coronary patterns that do not fit the usual origins and branching patterns from the ascending aorta. One such CAA includes a single coronary artery: a rare (often incidental) finding of only 1 coronary artery supplying the entire heart. This anomaly poses risks to the patient, with complications such as myocardial infarction and sudden cardiac death. Our patient case was a woman with high-risk coronary artery disease (CAD) who was incidentally found to have a single coronary artery. This is an important anatomical anomaly that can alter signs, symptoms, and subsequent treatment of patients with CAD.
