Abstract Pulmonary venous connections may be infrequently abnormal in patients with tetralogy of Fallot (TOF). A special subgroup of partial anomalous pulmonary venous return,"scimitar cyndrome", and its coexistence with TOF is less frequently reported. It may proceed unnoticed, as cyanosis already predominates in the clinical picture. This uncommon association must be kept in mind for patients with TOF who have an accessory flow in the inferior vena cava, especially when all pulmonary venous return to the left atrium is not clearly seen.

Isolated anomalous origin of the right coronary artery from the main pulmonary artery is a rare congenital anomaly, and few cases have been reported in the pediatric age group. Here in, we report an asymptomatic case of a 2-month-old male infant who has been diagnosed as anomalous origin of the right coronary artery from the main pulmonary artery during the evaluation for cardiac abnormalities. For a suspicion on echocardiography, cardiac catheterization and coronary angiography performed to verify the diagnosis of anomalous origin of the right coronary artery from the main pulmonary artery. The patient underwent surgery and did well after two months follow up. Early diagnosis may prevent patients from cardiovascular complications.

El origen anómalo aislado de la arteria coronaria derecha desde la arteria pulmonar principal es una anomalía congénita rara y se han notificado pocos casos en la población pediátrica. En este artículo informamos el caso asintomático de un lactante varón de dos meses de edad al que se le diagnosticó origen anómalo de la arteria coronaria derecha desde la arteria pulmonar principal durante la evaluación realizada para detectar anomalías cardíacas. Debido a la sospecha durante una ecocardiografía, se realizaron un cateterismo cardíaco y una angiografía coronaria para verificar el diagnóstico del origen anómalo de la arteria coronaria derecha desde la arteria pulmonar principal. El paciente se sometió a la cirugía y estaba en buen estado en el seguimiento a los dos meses. El diagnóstico temprano podría evitar que los pacientes tengan complicaciones cardiovasculares.
