Flexible Band vs Rigid Ring for Degenerative Mitral Valve Disease
Flexible Band vs Rigid Ring for Degenerative Mitral Valve Disease
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.
Inclusion Criteria:

 -  severe primary mitral regurgitation due to degenerative mitral valve disease

 Exclusion Criteria:

 -  previous open cardiac surgery,

 -  indication for concomitant aortic valve replacement,

 -  left ventricle impairment (ejection fraction < 40%).
