1. A mitral valve replacement system for implantation at a native mitral valve between a left atrium and a left ventricle of a heart, the native mitral valve including native mitral valve leaflets connected to the left ventricle via chordae, the mitral valve replacement system comprising:
an anchor assembly expandable from a delivery configuration to an anchored configuration for engagement with a native mitral valve annulus and with a sub-annular gutter adjacent to where the native mitral valve leaflets remain attached to the annulus, the anchor assembly having a first expandable frame comprising: at least one sub-annular anchor foot, a supra-annular structure positionable in the left atrium, and one or more wire arms that extend between the supra-annular structure and the at least one sub-annular anchor foot, and a sub-annular hub coupled by one or more support arms to the at least one sub-annular anchor foot; and
an artificial valve assembly comprising a second expandable frame, the artificial valve assembly positionable radially inward of the anchor assembly in an operative condition in which the artificial valve assembly is mechanically attached with the anchor assembly.
