摘要：
A heart valve assembly (10) includes an annular prosthesis (14) and a valve prosthesis(14). The annular prosthesis includes an annular ring (18) for dilating tissuewithin a biological annulus and a conformable sewing cuff (20) extending radiallyfrom the annular member. The valve prosthesis includes a frame (32) and a valvecomponent. The annular ring is introduced into the biological annulus to dilatetissue surrounding the biological annulus and the sewing cuff conforms to tissueabove the biological annulus. Fasteners are directed through the sewing cuffto secure the annular prosthesis to the biological annulus. The annular prosthesismay include a baleen element for biasing fabric on the annular ring outwardlyto enhance sealing against the biological annulus. A valve prosthesis is thenadvanced into the sinus cavity, and secured relative to the annular prosthesis.The sewing cuff may enhance a seal between the valve prosthesis and annular prosthesis.
