1. A method, comprising:
delivering a heart valve apparatus coupled to a delivery catheter across a septum of a heart and into a left atrium of the heart, the heart valve apparatus comprising mitral ring having a central passageway and a plurality of anchors disposed within the central passageway;
deploying from the delivery catheter the mitral ring at a mitral valve of the heart such that the mitral ring and the central passageway are disposed circumferentially with respect to the mitral valve;
anchoring the mitral ring at the mitral valve by deploying the plurality of anchors;
extending a tether through the central passageway of the mitral ring such that a distal end of the tether is coupled to the mitral ring;
tightening the tether to a tightened configuration to decrease a circumference of an annulus of the mitral valve; and
removing the delivery catheter from the heart.
