Two-dimensional echocardiographic diagnosis of anomalous origin of the right pulmonary artery from the aorta: differentiation from aortopulmonary window.

Utilizing two-dimensional echocardiography, the diagnosis of anomalous origin of the right pulmonary artery from the aorta was made prospectively in a neonate who presented with signs of congestive heart failure. A complete echocardiographic evaluation, including both right parasternal short-axis and suprasternal long-axis scans, permitted differentiation from other defects in aortopulmonary septation.
