Physical factors affecting shading in echocardiography, shading concepts are demonstrated and compared with echoes



The concepts of shading are demonstrated and compared with echoes. A: Prosthetic mitral valve (MV). The echo- space beyond the sewing ring (*) represents the strong echo-reflecting shadow of the sewing loop. Direct echoes beyond the pseudo valvular self-expanding to the left ventricle (LV) represent echoes. B: Centre (arrow) overlays a series of echoes into the left ventricle. Pond, aorta, LA, left atrium.
