Overview

Mitral stenosis is a valvular heart disease characterized by the narrowing of the orifice of the mitral valve of the heart.

In normal cardiac physiology, the mitral valve opens during left ventricular diastole, to allow blood to flow from the left atrium to the left ventricle. Blood flows in the proper direction because during this phase of the cardiac cycle the pressure in the left ventricle is lower than the pressure in the left atrium, and the blood flows down the pressure gradient. In the case of mitral stenosis, the valve does not open completely, and to transport the same amount of blood the left atrium needs a higher pressure than normal to overcome the increased gradient.
