Figure 66. Selected video frames from right parasternal (A) and subcostal four-chamber (B) views of the morphological left ventricle (MLV) showing an aneurysm (Anu) protruding into the pulmonary outflow tract, causing an obstruction. The Anu is located just below the pulmonary valve (PV). A dilated main pulmonary artery (MPA) is also shown. (A) is a modified right parasternal view showing MLV to the left, PV in the middle with an Anu below the PV. (B) is a modified subcostal four-chamber view showing MLV to the right and Anu in the middle. (C) is a magnified view of (B), again illustrating the aneurysm and dilated MPA.
