Management of Conduit Stenosis and Iatrogenic Aortopulmonary Window Post-Ross Procedure.

This case report describes a 23-year-old male with a history of bicuspid aortic valve endocarditis managed with an emergency Ross procedure in 2020, whereby a xenograft pulmonary conduit prosthesis was implanted in the pulmonary position, followed by pulmonary conduit stenosis treated initially with high-pressure balloon dilatation 3 years later. The consequent diagnosis of iatrogenic aortopulmonary (AP) window, combined with severe recurrent pulmonary conduit stenosis, necessitated reoperation with right ventricle-to-pulmonary artery homograft replacement and repair of the AP shunt.
