Abstract:
The early outcomes of transaortic patch repair closure for aortopulmonary window are satisfactory, but the lifelong fate of the aorta and pulmonary artery remains unknown. We describe a 40-year-old patient with right pulmonary artery occlusion accompanied by aneurysmal dilation of the ascending aorta 38 years after transaortic repair of an aortopulmonary window. Operative findings revealed patch shrinkage and thrombotic occlusion of the right pulmonary artery. The dilated ascending aorta firmly adhered to the right pulmonary artery. After pulmonary artery thrombectomy, the right pulmonary artery was reconstructed and the dilated ascending aorta was replaced.
