This clinical study is a multicenter, prospective non-randomized observational study without concurrent or matched controls in which 150 patients receiving an SJM® Rigid Saddle Ring will be included. The primary objective of the study is to demonstrate the effectiveness of the SJM® Rigid Saddle Ring when used in mitral valve repair procedures.

Arms Assigned Interventions
SJM® Rigid Saddle Ring
The SJM® Rigid Saddle Ring is an annuloplasty ring comprised of a titanium core surrounded by a double-velour, polyester fabric sewing cuff.
Device: mitral valve repair (SJM® Rigid Saddle Ring)
mitral valve repair due to mitral degenerative or functional disease

  • Patient is pregnant or nursing;
  • Patient has active endocarditis;
  • Patient is actively participating in another study of an investigational drug or device;
  • Patients unavailable to follow-up visit (abroad residents, patients affected by neurological disorders...);
  • Patients who are intravenous drug abusers, alcohol abusers, prison inmates or unable to give informed consent;
  • Patients with a major non-cardiac evolving disease;
  • Patients with a life expectancy less than 1 year;
  • Patients are known to be noncompliant or are unlikely to complete the study;
