Abstract:
1. A multiple component heart valve assembly, comprising: an annular prosthesis implantable within a natural valve annulus, the annulus prosthesis comprising an annular member disposed around a central longitudinal axis for dilating tissue surrounding the annulus; a prosthetic valve separate and disconnected from the annular prosthesis, the prosthetic valve comprising a frame having a multiple lobular outer shape radially relative to the longitudinal axis for implantation above the natural valve annulus; one or more connectors for securing the prosthetic valve to the annular prosthesis after the annular prosthesis has been introduced into the natural valve annulus; and a flexible skirt extending radially from at least one of the annular prosthesis and the prosthetic valve the skirt being deformable to accommodate irregularities between the annular prosthesis and the frame for enhancing a seal between the prosthetic valve and the annular prosthesis.
