An infant with a single coronary artery originating from the right pulmonary artery branch is the subject of this report. He survived to the age of one month possibly because of the association of two ventricular septal defects. While the pulmonary vascular resistance remained high, perfusion of the heart muscle was accomplished due to the pulmonary hypertension. The electrocardiogram did not show typical signs of infarction, but poor left ventricular contractility was observed by echocardiogram. The diagnosis was made postmortem. This specific coronary malformation has not been previously described and needs to be included in the classification of congenital coronary arteries anomalies.
