1. A prosthetic mitral valve comprising:
- an anchor assembly comprising a ventricular anchor, an atrial anchor, and a central portion there between, the anchor assembly having an expanded configuration in which the ventricular anchor and the atrial anchor flare radially outwards relative to the central portion, further wherein the atrial anchor includes a plurality of atrial cells and the ventricular anchor includes a plurality of ventricular cells;
an annular strut frame disposed radially within the anchor assembly, wherein a first plurality of the atrial cells are positioned radially inwards relative to a second plurality of the atrial cells such that the first plurality of the atrial cells and the second plurality of the atrial cells radially overlap, and wherein the first plurality of atrial cells attach the strut frame to the anchor assembly; and
a plurality of replacement leaflets secured to the annular strut frame.

Abstract
A prosthetic mitral valve includes an anchor assembly, a strut frame, and a plurality of replacement leaflets secured to the annular strut frame. The anchor assembly includes a ventricular anchor, an atrial anchor, and a central portion there between. 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.
