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.
