[Abnormal origin of the right coronary artery from the pulmonary artery. A case report]

An asymptomatic 4-year-old girl with anomalous origin of the right coronary artery from the pulmonary trunk is reported. Echocardiography showed overall dilated coronary arteries with anomalous course of the right coronary artery anterior to the aortic root. During heart catheterization the catheter could be moved from the proximal pulmonary trunk into the aberrant right coronary artery. Because of the coronary-pulmonary steal phenomenon corrective surgery with aortic reimplantation of the right coronary artery is recommended even in asymptomatic patients.
