Abstract

A single coronary artery ostium with anomalous right coronary artery (RCA) origin from collateral circulation of the left anterior descending artery is a rare variant associated with multiterritorial ST elevation myocardial infarction and high surgical complexity.We present a 54-year-old man who suffered cardiac arrest secondary to pneumonia-induced myocarditis.Cardiac Computed Tomography Angiography (CCTA) revealed a 2.6 mm LAD-RCA fistula.Stress testing showed anterior ischemia with steal syndrome, and coronary angiography confirmed the anomaly.The patient underwent successful RCA revascularization.
