title: Early stenotic prosthesis failure after implantation of a stentless porcine aortic valve prosthesis.
abstract: Stentless biological aortic prostheses are used routinely in aortic valve replacement surgery, offering beneficial hemodynamics compared to stented biological valves of similar size. We report here a rare case of early stenotic prosthesis failure of a RootElan stentless porcine aortic valve prosthesis due to swelling at the bottom of the right coronary cusp of the prosthesis.
