title: Interarterial course of the right coronary artery: assessment with cardiac computed tomography and myocardial perfusion imaging.
abstract: A 50-year-old well-trained cyclist reported increasing brief episodes of chest pain over the last 8 years at maximum exercise during alpine bicycle training. Previous cardiac stress testing on a supine bicycle ergometer revealed nonspecific ST-T abnormalities. In June 2007, the patient was referred for computed tomography coronary angiography, which revealed a coronary anomaly, with the right coronary artery originating from the left coronary sinus and taking an interarterial course between the ascending aorta and the pulmonary trunk. There were no atherosclerotic alterations in the coronary arteries. Subsequent bicycle exercise stress and myocardial perfusion imaging revealed no myocardial perfusion defect.
