Mitral Valve Stenosis - Answer-- Characterized by NARROWING of mitral valve - Normal is 4-6 cm -Narrowed is less than 2.5 cm - Caused by RHEUMATIC FEVER -More common in WOMEN -Oxygenated blood comes back into heart into the left atrium and down through the mitral valve to the left ventricle - Complex: Stenosis leads to volume/pressure in left atrium, which results in atrial hypertrophy/dilation, which increases pressure/volume in the pulmonary circulation & causes PULMONARY EDEMA - Sim...
