What Increases Your Risk
The three main risk factors for
mitral valve stenosis are:
- History of
rheumatic fever. Unfortunately, since most individuals
do not know they had rheumatic fever, they may not know they are at
risk.
- Aging. Wear and tear of the mitral valve over time may cause it
to harden and narrow.
- Gender. About twice as many women as men
develop mitral valve stenosis.3
Less commonly, diabetes and
Marfan's syndrome can lead to mitral valve stenosis,
causing calcification, or hardening, of the mitral valve's base. This limits
the valve's flexibility and slows its rhythmic movements. However, these
conditions usually increase the likelihood of
mitral valve regurgitation rather than
stenosis.
Any condition that scars the valves, such as
endocarditis, may lead to mitral valve stenosis.
Little can be done to prevent mitral valve stenosis. Similarly,
once you develop the condition, you cannot prevent the onset of symptoms or
predict how quickly they will develop.
Fortunately, mitral valve stenosis can be treated, and few people
die from it.
