DEFINITION

The heart is constituted of 4 cavities, two atria and two ventricles.

The mitral valve is localized between the left atrium and the left ventricle.

A mitral stenosis is defined as a reduction of the surface of the mitral valve.

This illness is thus responsible for a disturbance in the evacuation of the blood from the left atrium toward the left ventricle.

This illness is now less frequent than before because its main cause is the rheumatic fever, a more and more rare illness in the industrialized countries.

Its treatment has been transformed by the contribution of the technique of dilation of the mitral valve by external way and of course the valvular surgical replacement.
