Flexible Band vs Rigid Ring for Degenerative Mitral Valve Disease

Mitral Valve Repair Using Flexible Bands Versus Complete Rings in Patients With Degenerative Mitral Valve Disease: a Prospective, Randomized Study

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%).
