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 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.
