title: Replacement of a thrombosed valve after the Bentall procedure.
abstract: A 50-year-old man developed thrombosis in the valve of a Björk-Shiley prosthesis that had been used for composite graft replacement of the aortic valve and ascending aorta 8 years previously. The thrombosed valve was removed, and because of the narrow aortic valve ring, it was replaced using patch enlargement of the aortic annulus without replacement of the conduit.
