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
