Single coronary artery with probable origin of the anomalous right coronary artery from a left atrial recurrent branch.
A 62-year-old woman presented for evaluation of chest pain. She ruled out for myocardial infarction, and subsequent non-invasive studies were diagnostic for ischemia. On coronary angiography, she was found to have a previously undescribed variant of single coronary artery, in which the anomalous right coronary artery probably arose from a left atrial recurrent branch. In this patient, the congenital anomaly was an incidental finding, since her clinical presentation was felt to be due to moderate obstructive disease of the left anterior descending artery, in the setting of poorly controlled systemic hypertension.
