Takedown of Yasui Operation for Neoaortic Route Obstruction with Anatomic Repair Using the Native Pulmonary Trunk

We present a 6-year-old girl with neoaortic route stenosis and neoaortic valve regurgitation following a Yasui operation. Despite progressive neoaortic route obstruction, systemic output was maintained through the native aortic valve, which grew sufficiently over time to allow an elective Yasui takedown. The Damus-Kaye-Stansel anastomosis was disconnected, the aortic arch was patched, and the Yasui baffle was removed, restoring neoaortic valve leaflet mobility. The right ventricle to pulmonary artery conduit was removed and the right ventricular outflow tract was reconstructed using the native pulmonary trunk after closing a diminished ventricular septal defect. The postoperative course was uneventful, without recurrent aortic stenosis or pulmonary regurgitation.
