Failed "stentless" bioprosthesis implantation into the aortic position in the presence of aortic annular deformation due to associated cardiac disease.

We report two cases of unsuccessful "stentless" bioprosthesis implantation into the aortic position in patients with hemodynamically significant aortic defect and aortic annular deformation due to associated cardiac disease (1. A calcified mitral annulus, without a hemodynamically significant defect, 2. Aortic annulus infiltration in the presence of infectious endocarditis /IE/).
Both reported cases eventually required stent bioprosthesis reimplantation. Experience with both cases evaluates aortic annular deformity as a potential contraindication to use of stentless bioprostheses into the aortic position.
