title: Aortic regurgitation due to perforation of the right coronary cusp 10 years after implantation of a freestyle stentless bioprosthesis.
abstract: Valve deterioration following aortic valve replacement using the Freestyle stentless bioprosthesis is related to cusp tear, operative injury, or infection. We report a patient with aortic regurgitation due to perforation of the right coronary cusp 10 years after implantation of a Freestyle stentless bioprosthesis in the absence of endocarditis.
