Abstract:
A prosthetic cardiac valve assembly and method of implanting the same is disclosed. In certain disclosed embodiments, the prosthetic valve assembly is an annuloplasty ring with an attached artificial valve. The prosthetic valve assembly can be secured to native heart tissue by suturing or other suitable method of the annuloplasty ring to the native heart tissue. The prosthetic valve leaflets of the prosthetic valve can also be anchored to the native heart tissue to prevent prolapse. In certain embodiments, the prosthetic valve leaflets are anchored to the native papillary muscles. In still other embodiments, the prosthetic valve assembly contains exactly the number of prosthetic valve leaflets as are in the native valve that the prosthetic valve assembly is configured to replace. With the prosthetic valve assembly properly positioned, it will replace the function of the native valve.
