The Anatomical History of a Single Coronary Artery Anomaly: A Case Report.

Single coronary artery(SCA) anomaly is a rare anomaly where the right and left coronary arteries arise from a single ostium in the sinus valsalva and feed the whole heart. Although asymptomatic in most cases, it can cause angina, syncope, myocardial infarction and sudden cardiac death. It is essential to diagnose it especially in terms of the risk of encountering clinical pictures such as sudden death at a young age and its association with other congenital anomalies. In this report, we present a patient with a SCA anomaly. During an emergency conventional angiography, a right coronary artery(RCA) arising from the left main coronary artery(LMCA) originating from a single ostium was detected in the aorta.
