title: Direct communication of a pulmonary artery with left atrium--report of a case with balloon occlusion studies and successful correction: a case report.
abstract: A 10 year old cyanotic boy had direct communication between right pulmonary artery and left atrium. During cardiac catheterization, the catheter-tip balloon occlusion of this communication resulted in restoration of arterial oxygen saturation to normal levels, predicting that surgical interruption of the communication would be curative. Successful surgical correction was achieved by interruption of the communication.
