FIG 19.22 Parasternal short-axis section of the left ventricle (LV) shows the mitral valve (MV), with its aortic and mural leaflets The right ventricle (RV) is anterior to the left ventricle FIG 19.23 Parasternal short-axis section of the left ventricle showing the two papillary muscles supporting the mitral valve Note the obliquity of the papillary muscles, with the inferior muscle adjacent to the septum but anterior to its superior counterpart FIG 19.24 Apical four-chamber view On this image the right atrium (RA) and right ventricle (RV), together with the left atrium (LA) and left ventricle (LV), can be seen Note the slight apical displacement of the tricuspid valve relative to the mitral valve FIG 19.25 Apical five-chamber view Anterior tilting from the apical fourchamber view reveals the left ventricular outflow tract In this image, the left atrium (LA), left ventricle (LV), aorta (AO), right atrium (RA) and right ventricle (RV) can all be seen
