  • an inner support structure having a downstream section, and an upstream section, wherein the upstream section has a cross-sectional area greater than the downstream section, the inner support structure being configured to be positioned at least partially on an atrial side of the native valve complex, and to apply an axial force directed toward a left ventricle; and

    an outer support structure having two or more engagement arms, wherein the engagement arms are coupled to the inner support structure,wherein the prosthesis is configured, upon implantation thereof, to clamp portions of leaflets of the native valve between the inner support structure and the engagement arms.
