Figure 1 A, Parasternal short-axis view at the level of the mitral valve. A cleft divides the aortic mitral leaflet into two segments in diastole. (MV, mitral valve). B, Parasternal short-axis view at the level of the mitral valve. Color Doppler shows the regurgitant jet coming through the cleft. C, Parasternal long-axis view shows a break in the aortic mitral leaflet. (LA, left atrium; LV, left ventricle; LVOT, left ventricular outflow tract). D, Parasternal long-axis view with color Doppler. The regurgitant jet passes through the cleft being directed posteriorly.
