Figure 2 (A) Parasternal long-axis view, in systole, in a patient with thin, mobile unattached chordae in the LVOT (solid arrow). (B) Subcostal long-axis view in a patient with high insertion of the anterolateral papillary muscle. Note that the papillary muscle sits high on the shoulder of the left ventricle. (C) Parasternal long-axis view in a patient with combined obstruction. Note the tunnel narrowing, the fixed chordae in the LVOT and the increased angle between the aorta and the interventricular septum. ANT LAT PAP MUS = anterolateral papillary muscle; AO = aorta; LA = left atrium; LV = left ventricle; RV = right ventricle.
