Mitral stenosis

Mitral valve obstruction; Heart mitral stenosis; Valvular mitral stenosis

Mitral stenosis is a disorder in which the mitral valve does not fully open. This restricts the flow of blood.

Mitral stenosis

Mitral stenosis is a heart valve disorder that narrows or obstructs the mitral valve opening. Narrowing of the mitral valve prevents the valve from opening properly and obstructs the blood flow from the left atrium to the left ventricle. This can reduce the amount of blood that flows forward to the body. The main risk factor for mitral stenosis is a history of rheumatic fever but it may also be triggered by pregnancy or other stress on the body such as a respiratory infection, endocarditis, and other cardiac disorders.

Heart valves

The valves of the heart open and close to control the flow of blood entering or leaving the heart.

There are four valves in the heart: aortic valve, mitral valve, tricuspid valve, and pulmonary valve. The valves are designed to control the direction of blood flow through the heart. The opening and closing of the heart valves produce the heart-beat sounds.
