Definition Mitral stenosis is a heart valve disorder that involves the mitral valve. This valve separates the upper and lower chambers on the left side of the heart. Stenosis refers to a condition in which the valve does not open fully, restricting blood flow. Alternative Names Mitral valve obstruction Causes, incidence, and risk factors Blood that flows between different chambers of your heart must flow through a valve. The valve between the two chambers on the left side of your heart is called the mitral valve. It opens up enough so that blood can flow from one chamber of your heart (left atria) to the next chamber (left ventricle). It then closes, keeping blood from flowing backwards. Mitral stenosis refers to when the valve cannot open as wide. As a result, less blood flows to the body. The upper heart chamber swells as pressure builds up. Blood may flow back into the lungs. Fluid then collects in the lung tissue ( pulmonary edema ), making it hard to breathe. See also: heart failure . In a...
High blood pressure, diabetes, heart disease, and other risk factors should be treated.
If you smoke, you should stop.
Treatment of TIA (transient ischemic attack, "warning strokes") may prevent future strokes.
Aspirin therapy (81mg a day or 100mg every other day) is now recommended for stroke prevention in women under 65 as long as the benefits outweigh the risks. It should be considered for women over age 65 only if their blood pressure is controlled and the benefit is greater than the risk of gastrointestinal bleeding and brain hemorrhage .

Even back pain caused by a spondylolisthesis and lumbar stenosis can be treated with physical therapy. Because spondylolisthesis and lumbar stenosis can cause nerve damage, surgery is the natural knee-jerk treatment option that people think about. Of course, surgical spinal fusion is the best option to stabilize the spine if the nerves are severely damaged and in jeopardy of further damage. But, what about a low grade spondylolisthesis and mild stenosis? Can surgery be avoided? Absolutely, the body is able to compensate for the misalignment of the passive, spinal structures with optimal functioning of the active, stabilizing muscles. That's right; bones, ligaments, and cartilage are passive structures that sometimes fail; thus, the muscles and nerves which actively control the muscles can compensate for the problem. The spine has two systems, the passive and the active system, which can balance each other out. This redundancy allows for one system to compensate for problems in the oth...
