Rheumatic mitral valve diseases (I05)

Clinical Information for Rheumatic mitral valve diseases (I05)

Mitral Valve Stenosis - Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.
