摘要：
A method of implanting a prosthetic apparatus preferably includes delivering the prosthetic apparatus to a native mitral valve and exposing ventricular anchors and a spacer body of the prosthetic apparatus from a distal end portion of a delivery apparatus. The ventricular anchors are controllably and forcibly expanded outwardly from the spacer body to an expanded configuration. The prosthetic apparatus is positioned relative to the native mitral valve such that native mitral valve leaflets are located between the ventricular anchors and the spacer body. The ventricular anchors are then contracted radially inwardly toward the spacer body to a compressed configuration. In the compressed configuration, the native mitral valve leaflets are secured between the ventricular anchors and the spacer body. After implantation, the spacer body is held between the native mitral valve leaflets, thereby blocking regurgitation and improving the function of the native mitral valve.
