title: Antegrade percutaneous valve implantation for mitral ring dysfunction, a challenging case.
abstract: The operative risk for reoperation of degenerated bioprosthetic valves or failing mitral-valve annuloplasty is higher compared with the risks for first isolated native valve repair or replacement (Astor et al., Eur Heart J 2008;29:2382-2387). In the presence of comorbidities, these risks increase exponentially. The recent introduction of transcatheter valve implantation opened new perspectives for the treatment of patients at very high surgical risk. We report a percutaneous mitral valve (MV) implantation using a transatrial approach within a MV ring using the Edwars Sapien XT valve.
