Abstract
The mitral valve apparatus comprises the annulus and a portion of myocardium located above and below it, the leaflets, the chordae tendineae and the papillary muscles (Fig. 1.1). The mitral valve apparatus and the left ventricle are so interdependent that there is no mitral valve defect that does not affect the left ventricle in some way, and, in turn, there is no morphological or functional alteration of the left v entricle that has no consequence, to a greater or lesser extent, for the mitral valve. Therefore, the mitral valve is not a passive structure that moves solely as a result of the forces generated by cardiac activity, but rather a structure with its own sphinteric activity concentrated mainly in the annulus, which contributes to the ventricle’s contractility and, in turn, is heavily affected by it.
