Perspective Therapeutic options for patients with FMR Current surgical options are limited Repair Undersized annuloplasty Double orifice repair New surgical approaches without substantive data Replacement Medical management is largely ineffective The MitraClip Therapy may be a reasonable alternative therapeutic option
