New Mitral Annuloplasty Ring Enables Oversizing of Transcatheter Heart Valve and Prevents Central or Paravalvular Leakage

Duerr and colleagues describe the experimental development of a mitral anuloplasty ring, which should facilitate later transcatheter valve-in-ring implantation. Two accompanying videos demonstrate valve expansion and implantation within the ring. The article illustrates the potential importance these new technologies are expected to gain in the near future.
