Mitral valve annuloplasty with U-shaped flexible band using Duran ring

To preserve the physiologic function and correct annular dilatation, U-shaped flexible band was applied for mitral valve annuloplasty in 6 cases. U-shaped flexible band was made by cutting Duran ring to the proper length of posterior annulus using Carpentier-Edwards ring sizer. Echocardiographic mitral regurgitation decreased from 3.8 +/- 0.4 to 0.7 +/- 0.5 after repair. All patients discharged without any complications. This annuloplasty method is effective for mitral insufficiency.
