Transcatheter closure of distal aortopulmonary window using Amplatzer device.

Aortopulmonary window is a rare congenital heart defect, often requiring open surgical closure. Distal windows with good margins from the semilunar valves and coronary artery origin are amenable for transcatheter closure. Experience in nonsurgical closure of such defects is limited. We report closure of distal aortopulmonary window in 2 patients with pulmonary arterial hypertension using Amplatzer duct occluder device.
