Neo-aorta Reconstruction with Retained Stented Patch in Norwood Procedure After Hybrid Palliation of High-risk Hypoplastic Left Heart Syndrome: a Case Report

Hybrid procedure of hypoplastic left heart syndrome, comprising ductus arteriosus stenting and bilateral pulmonary artery banding, is a good surgical option for initial palliative procedure for high-risk patients for Norwood procedure. However, ductal stenting may cause retrograde aortic blood flow obstruction. Furthermore, complete removal of stent while performing the Norwood procedure make the operation more difficult. We report a case that overcame these problems using a novel surgical technique.
