Saddle shape of the mitral annulus reduces systolic strains on the P2 segment of the posterior mitral leaflet.

30 Oct 2009 BACKGROUND: The three-dimensional saddle shape of the mitral annulus is well characterized in animals and humans, but the impact of annular nonplanarity on valve function or mechanics is poorly understood. In this study, we investigated the impact ... Read more...

Active adaptation of the tethered mitral valve: insights into a compensatory mechanism for functional mitral regurgitation.

11 Jul 2009 BACKGROUND: In patients with left ventricular infarction or dilatation, leaflet tethering by displaced papillary muscles frequently induces mitral regurgitation, which doubles mortality. Little is known about the biological potential of the mitral ... Read more...

Percutaneous mitral annuloplasty for functional mitral regurgitation: results of the CARILLON Mitral Annuloplasty Device European Union Study.

11 Jul 2009 BACKGROUND: Functional mitral regurgitation (FMR), a well-recognized component of left ventricular remodeling, is associated with increased morbidity and mortality in heart failure patients. Percutaneous mitral annuloplasty has the potential to ... Read more...
