Rare Anomaly of Right Coronary Artery Discovered on Diagnostic Coronary Angiography

Case

A 45-year-old male with history of Hodgkin’s lymphoma and radiation-induced cardiomyopathy was taken for diagnostic cardiac catheterization and coronary angiography for evaluation of asymptomatic stage B heart failure. Angiography revealed the patient to have an anomalous separate ostium of the right acute marginal artery, a finding that did not affect performance of the catheterization or patient outcome. In a review of the literature, we found the phenomenon of separate ostia of right coronary artery and acute marginal artery to be quite rare and not well documented.
