The anchor assembly includes a ventricular anchor, an atrial anchor, and a central portion therebetween. The ventricular anchor and the atrial anchor are configured to flare radially outwards relative to the central portion. The annular strut frame is disposed radially within the anchor assembly and is attached to the anchor assembly. The central portion is configured to align with a native valve orifice and the ventricular anchor and the atrial anchor are configured to compress native cardiac tissue therebetween. ## Claims ### Claim 1 A replacement mitral valve, comprising: a self-expandable valve assembly comprising an anchor assembly having a ventricular anchor, a central portion, and an atrial anchor, the valve assembly having a collapsed configuration and a self-expanded configuration in which the ventricular anchor and the atrial anchor are flared radially outward relative to the central portion, the atrial anchor having a larger maximum diameter than a maximum diameter of the ventricular anchor when the valve assembly is in the self-expanded configuration prior to delivery, the valve assembly including an annular strut frame disposed radially inward of the anchor assembly and attached to the atrial anchor of the anchor assembly in the collapsed configuration, wherein the anchor assembly and the annular strut frame are unitary; and a plurality of replacement leaflets secured to the valve assembly. ### Claim 2 (depends on 1) The replacement mitral valve of claim 1, wherein the maximum diameter of the ventricular anchor is less than 55 mm. ### Claim 3 (depends on 1) The replacement mitral valve of claim 1, wherein the atrial anchor has a maximum diameter that is 3-10% larger than the maximum diameter of ventricular anchor. ### Claim 4 (depends on 1) The replacement mitral valve of claim 1, wherein the plurality of replacement leaflets are secured to the annular strut frame. ### Claim 5 (depends on 1) The replacement mitral valve of claim 1, wherein the anchor assembly is made of a plurality of diamond-shaped cells joined together. ### Claim 6 (depends on 1) The replacement mitral valve of claim 1, wherein the anchor assembly is configured to foreshorten when transitioning from the collapsed configuration to the expanded configuration. ### Claim 7 (depends on 1) The replacement mitral valve of claim 1, wherein the anchor assembly is configured to take on an hour-glass shape. ### Claim 8 (depends on 1) The replacement mitral valve of claim 1, wherein tips of the atrial anchor point in an atrial direction. ### Claim 9 (depends on 1) The replacement mitral valve of claim 1, wherein the atrial and ventricular anchors are configured to compress native cardiac tissue therebetween. ### Claim 10 (depends on 1) The replacement mitral valve of claim 1, wherein the atrial anchor comprises a plurality of atrial tips and the ventricular anchor comprises a plurality of ventricular tips, wherein there are more ventricular tips than atrial tips. ### Claim 11 A replacement mitral valve, comprising: a valve assembly comprising an anchor assembly having a ventricular anchor, a central portion, and an atrial anchor, the valve assembly having a collapsed configuration and a self-expanded configuration in which the ventricular anchor and the atrial anchor are flared radially outward relative to the central portion, the atrial anchor having a maximum diameter that is 3-10% larger than a maximum diameter of the ventricular anchor in the self-expanded configuration prior to delivery, the valve assembly including an annular strut frame disposed radially inward of the anchor assembly and attached to the atrial anchor of the anchor assembly in the collapsed configuration, wherein the anchor assembly and the annular strut frame are unitary; and a plurality of replacement leaflets secured to the valve assembly. ### Claim 12 (depends on 11) The replacement mitral valve of claim 11, wherein the maximum diameter of the ventricular anchor is less than 55 mm. ### Claim 13 (depends on 11) The replacement mitral valve of claim 11, wherein the plurality of replacement leaflets are secured to the annular strut frame. ### Claim 14 (depends on 11) The replacement mitral valve of claim 11, wherein the anchor assembly is made of a plurality of diamond-shaped cells joined together. ### Claim 15 (depends on 11) The replacement mitral valve of claim 11, wherein the anchor assembly is configured to foreshorten when transitioning from the collapsed configuration to the expanded configuration. ### Claim 16 (depends on 11) The replacement mitral valve of claim 11, wherein the anchor assembly is configured to take on an hour-glass shape. ### Claim 17 (depends on 11) The replacement mitral valve of claim 11, wherein tips of the atrial anchor point in an atrial direction. ### Claim 18 (depends on 11) The replacement mitral valve of claim 11, wherein the atrial and ventricular anchors are configured to compress native cardiac tissue therebetween. ### Claim 19 (depends on 11) The replacement mitral valve of claim 11, wherein the atrial anchor comprises a plurality of atrial tips and the ventricular anchor comprises a plurality of ventricular tips, wherein there are more ventricular tips than atrial tips.
