What is mitral stenosis?

Narrowing . Mitral stenosis is a narrowing of the valve that controls the flow of blood from the left atrium to the left ventricle of the heart. This can have many causes and, depending upon the severity of the stenosis, may or may not cause symptoms. This must be followed, because the degree of stenosis can increase over time and require replacement.
Mitral valve. The mitral valve has to open properly to let blood flow into the left ventricle from the atrium. If it doesn't, we call this stenosis. It has to close to keep the blood flowing toward the body, if it doesn't we call this regurgitation or insufficiency. Either or both problems can exist with the valve if its abnormal. Insufficiency is more common.

Infections. Most common cause, although rare these days in the westernized world, is rheumatic fever (due to strep infectipns) in young age, which leads to scarring of the valve over time with narrowing - stenosis. Other infections (endocarditis) can lead to mitral stenosis as well. Read more...

What are the tests for mitral stenosis?

Echo, cath. Echocardiogram is the most common test for mitral stenosis, as the structure and function of the valve can be assessed visually. Cxr can give information regarding chamber size and valve calcification. Ekg and holter monitor can reveal atrial fibrilation, a common arrhythmia associated with mitral stenosis. Heart cath would reveal the hemodynamics and the need for surgical intervention. Read more...
