FIG 19.11 Subcostal transverse cut at the level of the abdominal vessels The inferior caval vein (ICV) is seen to the right of the spine and the aorta (AO) is seen to the left of the spine This suggests that atrial arrangement is normal with the right atrium on the right and the left atrium on the left FIG 19.12 Heart sectioned to simulate a posterior paracoronal cut obtained from the subcostal window to look at the atrial septum The left atrium (LA) and right atrium (RA) can well be visualized On this more posterior cut, only the left ventricle (LV) is visualized, as the right ventricle is located more anteriorly FIG 19.13 Subcostal coronal view tilted more anteriorly compared to Fig 19.12 More of the right ventricle (RV) can be seen, as well as the left ventricle (LV) and the left ventricular outflow tract The arrow points at the insertion of the aortic valve Ao, Aorta; RA, right atrium FIG 19.14 Subcostal coronal view of the right atrium demonstrating the entrances of the superior caval vein (SCV) and the inferior caval vein (ICV) to the right atrium (RA) The tricuspid valve can be seen on this image, as well as part of the right ventricle (RV) On the color Doppler at right, the flow from the superior caval vein comes toward the probe and is shown in red, while flow from the inferior caval vein is directed away from the probe and is seen as blue FIG 19.15 Subcostal short-axis cut taken at the level of the right ventricular outflow tract Both the right ventricle (RV) and left ventricle (LV) are shown The right ventricular outflow tract is visualized, as well as the pulmonary trunk (PA)
