Assessment of mitral stenosis by echocardiography

Assessment of mitral stenosis by echocardiography Colour Doppler Echocardiogram in Mitral Stenosis Right panel shows the parasternal long axis view. Doming of the anterior mitral leaflet is seen well and has the appearance of hockey stick. This appearance is classical of rheumatic mitral stenosis. Paradoxical movement of the posterior mitral leaflet is also visible. Normally posterior mitral leaflet moves posteriorly in diastole. Here there is a paradoxical anterior movement due to commissural fusion. Left atrium is dilated. Left panel shows parasternal short axis view. The mitral orifice is seen within the cross section of the left ventricle. The anterior and posterior leaflets are seen in cross section and are thickened; the commissures are fused. Parasternal long axis view will give an assessment of the subvalvar apparatus. Subvalvar fusion may result in poor results after valvotomy as they can produce secondary obstruction beyond the valve. Parasternal short axis view is used for quantitating the severity of mitral stenosis by using planimetry to measure the mitral valve orifice. Commissural fusion and calcification if present can be seen well on PSAX view. Trans mitral gradient is better assessed in apical four chamber view by Doppler. Associated tricuspid regurgitation if present, can be seen on apical four chamber view, which will also help in estimating the right ventricular systolic pressure from the TR.
