Abstract
Examples of a mitral heart valve apparatus are described. In one example, the apparatus has an annular body made of a first material, and a plurality of first anchor members and at least two paddles made of a second material extending from the annular body. In a compressed state, the first anchor members extend substantially longitudinally from the first end of the annular body, and the paddles extend substantially longitudinally from the second end of the annular body. In an expanded state, the annular body has a larger diameter, the first anchor members extend outward from the first end for engaging an upstream portion of a mitral valve annulus to resist displacement of the annular body towards a left ventricle, and the paddles extend outward from the second end for engaging chordae tendineae. In another example, the annular body, anchor members, and paddles are made of the same material.
