St elevation myocardial infarction in a patient with an anomalous right coronary artery originating from the distal left circumflex

Abstract

A single coronary artery (SCA) is a rare congenital anomaly that occurs in isolation without associated structural heart disease. Reports of a SCA with acute myocardial infarction are very rare in medical literature. This case study examines a patient with a right coronary artery that originated as a branch of the distal left circumflex artery, which had a total occlusion.
