title: Aortic valve replacement 13 years following Bentall procedure.
abstract: Aortic valve dysfunction secondary to leaflet degeneration of porcine bioprosthesis incorporated in a conduit poses a challenge to the surgeon. An adult male required repeat aortic valve replacement 13 years following insertion of an intraoperatively constructed conduit composed of a Carpentier-Edwards bioprosthesis and Dacron tube graft. At surgery, the extremely difficult situation was easily resolved by excising the degenerated leaflets and inserting a St. Jude aortic valve within the frame of the bioprosthesis. The patient has remained Class I during the 3-year follow-up period, enjoying normal aortic valve function.
