Dynamic annuloplasty for mitral regurgitation [PDF]

The Journal of Thoracic and Cardiovascular Surgery, 2013
The MiCardia DYANA annuloplasty system (MiCardia Corp, Irvine, Calif) is a nitinol-based dynamic complete ring that allows modification of the septal-lateral diameter under transesophageal echocardiography guidance in the loaded beating heart after mitral valve repair. Shape alteration is induced by radiofrequency via detachable activation wires.

Mitral annuloplasty using an intra-annular ring [PDF]

, 2012
The final step in mitral valve repair is usually the implantation of an annuloplasty ring which remodels the dilated annulus and improves the long-term durability of repair.

Edge-to-edge with partial band mitral valve repair compared to replacement and undersized restrictive annuloplasty for ischemic mitral regurgitationCentral MessagePerspective

JTCVS Techniques
Objective: Evidence supports replacement over repair for ischemic mitral regurgitation due to improved durability; however, the latter often involves an undersized ring annuloplasty that does not include edge-to-edge approximation.

The Influence of Mitral Annuloplasty on Left Ventricular Flow Dynamics [PDF]

, 2015
BackgroundMitral valve (MV) repair using annuloplasty rings is the preferred method of treatment for MV regurgitation, but the impact of annuloplasty ring placement on left ventricular intraventricular flow has not been studied.MethodsAnnuloplasty rings ...

Recurrent mitral regurgitation after annuloplasty for functional ischemic mitral regurgitation [PDF]

, 2004
ObjectivesWe sought to characterize the temporal return of mitral regurgitation after annuloplasty for functional ischemic mitral regurgitation; to identify its predictors, particularly with respect to annuloplasty type; and to determine whether ...
