(2) Mitral regurgitation ⚫ Causes: pathology of the mitral leaflets, subvalvular mechanism (chordae or papillary muscles) or mitral annulus. ⚫ The haemodynamic consequence of mitral regurgitation is systolic increase in left atrial pressure and pulmonary venous pressure during systole. ⚫ Plain radiography shows various degrees of pulmonary venous hypertension and cardiomegaly. The severity of pulmonary venous hypertension is generally less than in predominant mitral stenosis. Cardiomegaly is a consequence of left atrial and left ventricular enlargement. 15’ 15’ 15’ 10’
