Who is affected by mitral valve stenosis

It is unknown how many people have mitral valve stenosis. But it is not common in developed countries such as the United States, Canada, and western Europe. Most people do not have symptoms of this condition until they 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.1
