DEFINITION

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

The aortic valve is localized between the left ventricle and the artery coming out of the heart, the aorta.

An aortic stenosis is defined as a reduction of the surface of the aortic valve.

This illness is thus responsible for a disturbance in the evacuation of blood out of the heart.

The aortic stenosis is the most frequent illness of the heart valves, and found mainly in the elderly subject. Now we are attending an increase in the number of patients affected by this illness, because of the population’s ageing.

Its radical treatment is based on the replacement of the aortic valve by a prosthesis.
