1. A prosthetic mitral valve, comprising:
a valve support assembly configured to self-expand from a collapsed configuration to an expanded configuration and including an anchor assembly having a ventricular anchor, a central portion, and an atrial anchor, wherein, in the expanded configuration, the atrial anchor flares outwardly relative to the central portion, the valve support assembly including a strut frame positioned radially inward of the anchor assembly and attached to the anchor assembly;
a plurality of leaflets attached to the valve support assembly;
a plurality of retention hooks attached to the ventricular anchor of the anchor assembly, wherein the plurality of retention hooks curve radially outward to point in an atrial direction when the valve support assembly is in the expanded configuration; and
a skirt configured to form around an external surface of the anchor assembly, wherein the skirt includes a plurality of pre-formed cuts configured to provide access to the plurality of retention hooks.
