Overview
Causes of Mitral stenosis
Acquired Mitral Stenosis:
- Rheumatic heart disease: MS is synonymous with rheumatic fever which occurs as a complication of group A streptococcal infection in genetically susceptible individuals.
- There are primary causes of mitral stenosis that emanate from a cleft mitral valve.
- Prosthetic mitral valve.
- Mitral valve obstruction from left atrial myxoma.
- Mitral annular calcification.
- Bacterial endocarditis where the vegetations may favor increase risk of stenosis.
- Radiation treatment to the chest.
- Some medications may cause mitral stenosis.
Congenital 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. This is a rare entity which includes the following:
- Hypoplasia of mitral valve annulus which is considered part of the spectrum of hypoplastic left heart syndrome,
- Mitral valve commissural fusion,
- Double orifice mitral valve,
- Thickened chordae tendinae, and
- Shone's syndrome which consists a set of four cardiac defects:
- Parachute mitral valve,
- Supra-valve mitral membrane (SVMM),
- Sub-aortic stenosis,
- Coarctation of the aorta,
Mitral stenosis may run in families.
