title: Anomalous origin of the right coronary artery from the main pulmonary artery: diagnosis and management.
abstract: Anomalous origin of the right coronary artery (ARCA) from the main pulmonary artery (MPA) is a rare congenital anomaly, with only 18 reported cases in the pediatric age group. More than half of these had associated cardiac anomalies that masked the presence of ARCA. Conversely, in many patients with ARCA as an isolated anomaly, the diagnosis has been missed during lifetime. The only patient with an isolated ARCA who was diagnosed in infancy presented with congestive heart failure. Asymptomatic infants with ARCA from the MPA have not been previously reported. Three additional cases, two infants and a child with ARCA from the MPA, are reported in this paper. The diagnostic dilemmas and the prognosis are discussed and management is recommended.
