Abstract
This report describes an infant with double-outlet right ventricle who underwent pulmonary artery banding as palliation for excessive left to right shunting through a ventricular septal defect. Three weeks after this procedure, there was abrupt clinical deterioration, and two-dimensional echocardiography clearly defined a large pseudoaneurysm arising from a breach in the posterior pulmonary artery wall, just proximal to the band. The diagnosis was confirmed at surgery, during which total correction was performed with successful outcome. The two-dimensional echocardiographic features of a pseudoaneurysm of the pulmonary artery are shown and the role of this noninvasive technique in the evaluation of pulmonary artery bands is discussed.
