Probe position: From the PLAX position, rotate the probe 90o so the probe marker points towards the left shoulder. You will see the following structures:
IVS = interventricular septum, LV = left ventricle, PmP = posteromedial papillary muscle, AlP = anterolateral papillary muscle, IW = inferior wall of left ventricle.
