Abstract

Normal myocardium is usually perfused by three coronary arteries- a left main system bifurcating into left anterior descending artery (LAD), and left circumflex artery (LCx), and right coronary artery (RCA). Coronary artery anomalies are congenital changes in their origin, course, and/or structure, which are usually discovered as incidental findings during coronary angiographic studies. Here, we report a case of 56-year-old hypertensive, and diabetic male who was being evaluated for exertional angina and dyspnoea whose coronary angiogram revealed a rare coronary anomaly: normal LAD, absent LCx, and superdominant RCA which was better delineated on Multidetector coronary angiography (MDCT). Multislice CT is the non-invasive modality of choice for imaging anomalies of coronary arteries and provides high speed with excellent spatial resolution.
