We describe a 50-year-old man who was diagnosed with anomalous aortic origin of the right coronary artery（AAORCA）by coronary angiography and coronary computed tomography performed for chest pain on exertion. Exercise-loaded myocardial scintigraphy revealed inferior wall ischemia, and hence surgery was performed. Intraoperatively, the right coronary artery was seen to run in the aortic wall, and hence, right coronary ostioplasty（unroofing）was performed. Postoperatively, coronary computed tomography revealed that the right coronary artery originated from a normal position, and exercise-loaded myocardial scintigraphy indicated no ischemia.
