RESUMO
Anomalous origin of the right coronary artery (RCA) from the pulmonary artery (PA) is a rare congenital anomaly, and only 28 cases have been reported in the pediatric age group. We describe the case of an infant who had progressive mitral regurgitation and papillary muscle dysfunction in association with anomalous origin of the RCA from the PA. The diagnosis was made by color flow Doppler, confirmed by angiography, and the case was successfully corrected by reimplantation of the anomalous RCA to the aorta. This is only the second case of anomalous origin of the RCA from the PA diagnosed in infancy without an associated congenital anomaly of the heart and great vessels.

A previously healthy 4-year old male, born in India and residing in Mobile, Alabama since October 1996 came to the emergency department in April 1997 because of general malaise, fever and vomits of 5 days duration. A peripheral smear of the complete blood count revealed the presence of malarial parasites within the erythrocytes. Plasmodium vivax was later identified in serial thin peripheral smears. He defervesced after initial treatment with oral quinine and pyrimethamine-sulfadoxine, followed by primaquine for 14 days.
