Images obtained with a low frequency phased array transducer in the third left intercostal space, with the probe marker rotated 90° clockwise from the parasternal long axis, then fanning in a cephalad direction.
Image 1 (blue labels) shows a normal parasternal short axis at the level of the papillary muscles
Image 2 (red labels) shows a normal parasternal short axis at the mitral valve level
Image 3 (red labels) shows a normal parasternal short axis at the base of the heart
