Right pulmonary artery left atrium communication.

A 12-year-old boy presented with central cyanosis, clubbing, and ejection systolic murmur in the left second and third intercostal space. Chest roentgenogram showed a round opacity on the right border of cardiac silhouette. Echocardiography revealed a communication between right pulmonary artery and left atrium, which was later confirmed on selective pulmonary cineangiography. Successful surgical ligation without cardiopulmonary bypass resulted in the cure of the disease.
