RADIOLOGY OF AORTIC DISEASES
MITRAL STENOSIS .
Mitral valve stenosis is a valvulopathy that describes narrowing of the opening of
the mitral valve between the left ventricle and the left atrium.
Mitral stenosis is usually acquired via rheumatic heart disease, where there is
chronic inflammation of the mitral valve leaflets (mitral valvulitis) . This leads to
progressive and diffuse fibrous thickening of the valve leaflets, and development
of valvular calcifications . Eventually, the mitral commisures fuse and the chordae
tendinae fuse . This culminates in significant immobilization and narrowing of the
mitral valve, giving it a characteristic 'fish mouth' appearance . Many patients will
also have concurrent mitral regurgitation due to the valve being unable to
sufficiently close
At echocardiography, the important features of mitral stenosis are enlargement of
the ltft atrium, thickening if the valve leaflets and restriction of the valve
movement.
The plain chest radiograph reveals left atrial enlargement, possibly calcification of
the mitral valve and evidence of raised pulmonary venous pressure and pulmonary
oedema. In the mitral stenosis at the X ray film observed a sharp swelling of left
atrium and expansion of pulmonary artery
