Case Discussion
A case of mitral stenosis due to rheumatic heart disease:
- normal area of mitral valve is 4-6 cm2
- area less than 2 cm2 is considered stenotic
- x-ray findings are noted at areas <1 cm2
- left atrial enlargement causes double right heart border
- straightened left heart border is formed by (from superior to inferior):
- aortic knuckle
- prominent left pulmonary conus (due to pulmonary hypertension)
- concave left atrial appendage (normally convex)
- left ventricle shadow
