RESUMEN
We report two cases of transcatheter-device closure of aortopulmonary windows, a residual defect occurring after previous surgical closure, and a native lesion. The postsurgical defect was closed with an Amplatzer Duct Occluder II (AGA Medical Corporation, MN). The native lesion was not suitable for an Amplatzer Duct Occluder II device; thus, it was closed using an Amplatzer Duct Occluder (AGA Medical Corporation, MN). The Amplatzer Duct Occluder II provides an additional device for aortopulmonary window closure, but anatomy and defect characteristics dictate the most appropriate device.

A 10-year old girl underwent a CT angiogram to investigate right lung hypoplasia. This showed a normal bronchial tree, lung parenchyma and pulmonary venous drainage, but an absent right pulmonary artery. Cardiac catheterization with pulmonary vein wedge injections identified a disconnected hypoplastic right pulmonary artery system supplied by an occluded right-sided ductus arteriosus. Transcatheter recanalization of the ductus re-established right pulmonary artery flow and growth. Ultimately, this allowed for complete surgical repair and restoration of normal perfusion of the right lung, leading to complete functional rehabilitation.
