abstract

Mitral valve (MV) disease is the most prevalent form of heart valve disease among the US population [1]. MV disease can affect any one of the four components of the mitral valve: chordae tendinae, valve leaflets, papillary muscles or the supporting annulus. In one example of MV disease the annulus can become dilated, and this can subsequently lead to mitral valve insufficiency. Various surgical and catheter based techniques have been developed for repair or replacement of a dysfunctional MV, and many of these procedures involve suturing or anchoring devices directly to the annulus, thus restricting further dilatation of the annulus.
