We report a rare case of anomalous origin of obtuse marginals (OMs) from a common trunk arising from the right coronary sinus in an interesting armchair shape in a 52-year-old female presenting with acute inferior wall myocardial infarction. During routine coronary angiography, the origin of the left anterior descending coronary artery was visualized and the origin of the left circumflex (LCX) coronary artery was not visualized with the sign of nonperfused myocardium in the LCX artery territory. Our case is a rare illustration of armchair OMs with nonperfused proximal and middle LCX coronary artery territory.
