title: Bioprosthetic dysfunction caused by preserved native valve in tricuspid position.
abstract: We report a 4-year-old girl who underwent replacement of a bioprosthetic valve in the tricuspid position due to rare bioprosthetic dysfunction. The bioprosthetic valve showed marked tricuspid insufficiency as well as stenosis caused by the adhesion of the preserved native valve leaflets to the undersurface of the implanted bioprosthesis.
