1. A replacement mitral valve, comprising:
- a self-expandable anchor comprising a ventricular anchor comprising a plurality of ventricular arches, a central portion, and an atrial anchor comprising a first annular frame with a plurality of first atrial arches and a plurality of first atrial apertures therethrough and a second annular frame having a plurality of second atrial arches and a plurality of second apertures therethrough;
the atrial anchor secured to the central portion and not integral with the central portion,the self-expandable anchor having a self-expanded configuration in which the ventricular anchor and the atrial anchor are flared radially outward relative to the central portion such that the replacement mitral valve is configured to be secured within a mitral valve orifice,wherein the central portion includes a plurality of central apertures therethrough, each of the plurality of first atrial apertures in alignment with one of the plurality of central apertures to form a plurality of first pairs of aligned apertures, and each of the plurality of second apertures is in alignment with one of the central portion apertures to form a plurality of second pairs of aligned apertures;
a plurality of first couplers, each of which extends through one of the plurality of first pairs of aligned apertures to fasten the central portion to the first annular frame and a plurality of second couplers, each of which extends through one of the plurality of second pairs of aligned apertures to fasten the central portion to the second annular frame; and
a plurality of replacement leaflets secured to the expandable anchor.
