Who is affected by mitral valve stenosis

It is unknown how many people have mitral valve stenosis. Most people do not have symptoms of this condition until after age 40. Usually, symptoms appear in people who are in their 50s or 60s.¹ People in this age group often have more than one heart problem at the same time, which can make it more difficult to diagnose and treat mitral valve stenosis.

About twice as many women as men develop mitral valve stenosis.²
