Prophylactic Pulmonary Artery Reduction in a Young Female with Severe Pulmonary Hypertension from Complete Atrioventricular Septal Defect

Management of severely dilated pulmonary artery (PA) associated with severe pulmonary hypertension from congenital heart disease remains controversial, primarily due to its rare nature and concern for perioperative unpredictable complications. Herein, we report a 25 year-old female with a severely dilated PA (up to 73 mm), who was successfully treated by a PA graft replacement by creating a Y-shaped conduit using a 28 mm hemashield tube in the main PA and a 20 mm hemashield tube in both proximal parts of the branch PA.
