title: Stented within a stentless aortic valve. A simple surgical solution for the replacement of a stentless aortic bioprosthesis.
abstract: Stentless aortic bioprostheses are designed to offer better hemodynamics, less mechanical stress to the leaflets and as a result less degeneration. Although encouraging results are reported, little evidence has been published regarding reoperations of stentless valves. We are reporting a case of a structural valve dysfunction of an O'Brien-Angell stentless prosthesis, which could not be extracted during reoperation without damaging the aortic root. We are presenting a simple, quick and effective surgical solution, the surgical 'valve within a valve' technique for the avoidance of a redo complex root procedure.
