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

Area of Science:

• Pediatric Cardiac Surgery
• Congenital Heart Disease
• Aortic Valve Reconstruction

Background:

• A 6-year-old female presented with neoaortic route stenosis and regurgitation post-Yasui operation.
• Progressive obstruction of the neoaortic route was noted, yet systemic output was maintained.
• Native aortic valve growth compensated for the obstruction, enabling surgical intervention.

Purpose of the Study:

• To describe the successful surgical management of neoaortic route stenosis and regurgitation in a pediatric patient.
• To detail the technique of Yasui takedown and subsequent cardiac reconstruction.
• To evaluate the functional recovery of the neoaortic valve and overall cardiac status post-intervention.

Main Methods:

• Performed elective Yasui takedown, involving disconnection of the Damus-Kaye-Stansel anastomosis.
• Repaired the aortic arch and removed the Yasui baffle to restore neoaortic valve leaflet mobility.
• Removed the right ventricle to pulmonary artery conduit and reconstructed the right ventricular outflow tract using the native pulmonary trunk, closing a ventricular septal defect.

Main Results:

• The surgical procedure successfully relieved neoaortic route stenosis and regurgitation.
• Restored neoaortic valve leaflet mobility and improved outflow tract function.
• The postoperative course was uneventful, with no recurrence of aortic stenosis or pulmonary regurgitation.

Conclusions:

• Yasui takedown is a viable option for managing neoaortic route stenosis and regurgitation in select pediatric patients.
• Surgical reconstruction can effectively restore neoaortic valve function and improve long-term outcomes.
• This case highlights the potential for native aortic valve growth to facilitate later surgical correction.
