A heart valve assembly includes a prosthesis for receiving a prosthetic valve to replace a preexisting natural or prosthetic heart valve within a biological annulus adjacent a sinus cavity. The prosthesis includes an annular member implantable within the biological annulus for contacting tissue surrounding the biological annulus to provide an opening through the biological annulus, a collar extending upwardly from the annular member, and a sewing cuff extending radially outwardly from the annular member and/or collar. Optionally, the annular member and/or collar may be resiliently compressible, expandable, and/or otherwise biased. A valve member, e.g., a mechanical or bioprosthetic valve may be coupled to the collar, e.g., using a drawstring, sutures, or other connectors, to secure the valve member to the gasket member.

1. A heart valve assembly, comprising: an annular prosthesis implantable within a natural valve annulus, the annular prosthesis comprising an annular member configured to be received in a biological annulus, a sewing cuff extending radially outwardly from the annular member, and a collar extending upwardly from the annular member; anda prosthetic valve comprising a frame securable to the collar, wherein the frame includes a first ear and a second ear, wherein the first and second ears extend downwardly from the frame,wherein the collar includes a first pocket configured to receive the first ear and a second pocket configured to receive the second ear, andwherein the collar defines an interior lumen having a longitudinal axis, wherein the collar includes an internal wall and an external wall, wherein the internal wall is closer to the longitudinal axis than the external wall, and wherein the first and second pockets are formed in the internal wall of the collar. 2. The heart valve assembly of claim 1, further comprising one or more connectors for securing the prosthetic valve to the annular prosthesis. 3. The heart valve assembly of claim 2, wherein the one or more connectors comprises a drawstring on the collar. 4. The heart valve assembly of claim 1, wherein the prosthetic valve comprises a mechanical valve. 5. The heart valve assembly of claim 1, wherein the prosthetic valve comprises a bioprosthetic valve. 6. The heart valve assembly of claim 1, wherein the first and second pockets are open to the interior lumen. 7. A method for implanting a prosthetic heart valve assembly to replace a natural or prosthetic heart valve implanted within a biological annulus below a sinus cavity, the method comprising: obtaining a gasket member comprising an annular ring sized for delivery into the biological annulus, the gasket member comprising an annular transition extending upwardly from the annular ring, wherein the annular transition comprises a first pocket and a second pocket, wherein the annular transition defines an interior lumen having a longitudinal axis, wherein the annular transition includes an internal wall and an external wall, wherein the internal wall is closer to the longitudinal axis than the external wall, arid wherein the first and second lockets are formed in the internal wall of the annular transition;obtaining a valve member that has a cross-section larger than the annular ring, wherein the valve member comprises a frame including first and second ears extending downwardly from the frame, and wherein the first ear is configured to mate with the first pocket and the second ear is configured to mate with the second pocket to secure the valve member to the frame;connecting the valve member to the annular transition to provide a heart valve assembly;introducing the heart valve assembly towards the biological annulus such that the annular ring is disposed within the biological annulus and the valve member is disposed within the sinus cavity; andsecuring the heart valve assembly to tissue adjacent the biological annulus. 8. The method of claim 7, wherein the first and second pockets are open to the interior lumen. 9. A method for implanting a prosthetic heart valve assembly within a biological annulus, comprising: obtaining a heart valve assembly comprising an annular member sized for delivery into the biological annulus, an annular transition extending upwardly from the annular ring, and a valve member secured to the annular transition that has a cross-section larger than the annular member, wherein the valve member comprises a frame including first and second ears extending downwardly from the frame, wherein the annular transition includes a first pocket configured to receive the first ear and a second pocket configured to receive the second ear, wherein the annular transition defines an interior lumen having a longitudinal axis, wherein the annular transition includes an internal wall and an external wall, wherein the internal wall is closer to the longitudinal axis than the external wall, and wherein the first and second pockets are formed in the internal wall of the annular transition;introducing the heart valve assembly towards the biological annulus such that the annular member is disposed within the biological annulus and the valve member is disposed above the biological annulus; andsecuring the heart valve assembly to tissue adjacent the biological annulus. 10. The method of claim 9, wherein introducing the heart valve assembly comprises: placing a plurality of sutures through tissue surrounding the biological annulus;directing the sutures through portions of the heart valve assembly; andadvancing the heart valve assembly down the sutures until the annular member is disposed within the biological annulus. 11. The method of claim 10, wherein the heart valve assembly is secured to tissue adjacent the biological annulus by tying knots in the sutures. 12. The method of claim 9, wherein the annular transition comprises a collar including an upper edge to which the valve member is secured, the annular transition providing a transition inwardly from the upper edge towards the annular member for facilitating flow through the heart valve assembly. 13. The method of claim 9, further comprising selecting a valve member having a predetermined size corresponding to a sinus cavity above the biological annulus, and securing the selected valve member to the annular transition. 14. The method of claim 9, wherein the first and second pockets are open to the interior lumen.
