1. A method of delivering a replacement valve to a native mitral valve of a heart and securing the replacement valve relative to a native mitral valve annulus, the native mitral valve positioned between a left atrium and a left ventricle, the method comprising:

  • delivering the replacement valve to the native mitral valve annulus while the replacement valve is in a radially compacted state, the replacement valve comprising;

    an expandable frame having a proximal end ending at a proximalmost end and a distal end ending at a distalmost end;

    a valve body positioned within a lumen of the expandable frame; and

    one or more distal anchors extending from the distal end of the expandable frame and sized to contact tissue on a ventricular side of the native mitral valve when the replacement valve is deployed within the native mitral valve; and

    deploying the replacement valve within the native mitral valve annulus such that;

    the replacement valve is in an expanded configuration with a cross-sectional diameter of the distalmost end of the expandable frame being greater than a cross-sectional diameter of the proximalmost end of the expandable frame, the replacement valve only decreasing or remaining constant in cross-sectional diameter from the distalmost end to the proximalmost end;

    the one or more distal anchors are positioned radially outwardly from the frame;

    tips of the one or more distal anchors extend substantially parallel to a longitudinal axis of the expandable frame; and

    at least one of the distal anchors extends between chordae tendineae of the native mitral valve.
