Abstract

The mitral valve is part of the left ventricular outflow tract and of the aortic root; it facilitates the accommodation of blood, eventually followed by its rapid, efficient, and forceful ejection through the left ventricular outflow tract into the aortic root.

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 ventricle 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 sphincteric activity concentrated mainly in the annulus, which contributes to the ventricle’s contractility and, in turn, is heavily affected by it.

The mitral valve apparatus comprises the annulus and portion of myocardium located above and below it, the leaflets, the chordae tendineae, and the papillary muscles.
