Mitral stenosis causes

Causes of Mitral stenosis include:

• Almost all cases of mitral stenosis are due to disease in the heart secondary to rheumatic fever and the consequent rheumatic heart disease.
• Calcification of the mitral valve leaflets.
• There are primary causes of mitral stenosis that emanate from a cleft mitral valve.
• Bacterial endocarditis where the vegetations may favor increase risk of stenosis.
• Radiation treatment to the chest.
• Some medications may cause mitral stenosis.

Children may be born with mitral stenosis (congenital) or other birth defects involving the heart that cause mitral stenosis. Often, there are other heart defects present, along with the mitral stenosis. Mitral stenosis may run in families. Mitral stenosis is the most common valvular heart disease in pregnancy.
