Context: Coronary artery anomalies are uncommon and most are incidental fi ndings. Double right coronary artery (RCA) is a very rare coronary artery anomaly. Case Report: We report two cases of double RCA incidentally found in electrocuted patients. Both cases showed double RCA arising from separate ostia. On microscopy, both right coronaries showed no signifi cant pathology in the fi rst case while in the second case, the posterior RCA showed features of obliterative arteritis. Conclusion: Although double coronary artery has been regarded as hemodynamically insignifi cant, it may be associated with atherosclerosis, acute coronary syndromes, and other anomalies. It is important to know the anatomic variants. Meticulous grossing and careful observation could unearth hidden anomalies
