The study evaluates the results of mitral valve repair with flexible band in comparison with rigid ring in patients undergoing mitral valve repair for degenerative mitral valve disease
Currently, mitral ring selection is based on a surgeon's preference rather than evidence. Semirigid rings combine flexibility and stability; however, their clinical benefit has not been completely clarified. The present study aimed to compare the outcomes of mitral valve repair with a flexible posterior annuloplasty band versus complete semirigid ring in patients with degenerative mitral valve disease.

Mitral valve annuloplasty using Cardiamed (Penza, Russia) flexible posterior annuloplasty band
Mitral valve annuloplasty using Cardiamed (Penza, Russia) complete semirigid ring
Freedom from significant mitral regurgitation
Significant mitral regurgitation is defined as moderate and severe mitral regurgitation. The severity of MR was evaluated and defined in accordance with the European Association of Echocardiography recommendations for the assessment of valvular regurgitation
Time frame: 12 months
Survival
Continued existence at follow up
Time frame: 12 months, 24 months
Freedom from reoperations
Freedom from redo mitral valve surgery during follow up
Time frame: 12 months, 24 months
Freedom from severe MR recurrence
The severity of MR was evaluated and defined in accordance with the European Association of Echocardiography recommendations for the assessment of valvular regurgitation
Time frame: 12 months
