ABSTRACT:
A heart valve assembly including an annular prosthesis implantable within a biological annulus, a prosthetic valve including a multiple lobular shape for implantation above the biological annulus, and one or more connectors for securing the prosthetic valve to the annular prosthesis. A flexible sewing cuff extends radially from the annular prosthesis that is resiliently flexible for conforming to the multiple lobular shape of the prosthetic valve to enhance a seal between the prosthetic valve and the annular prosthesis. The sewing cuff may include a core resiliently conformable with anatomy surrounding the biological annulus and fabric covering at least a portion of the core.
