An alternative would be to place the right ventricle into the far field of the imaging sector by imaging from the subcostal position.
In newborns and infants, this anatomy is revealed particularly well from the subcostal window.
These features can be demonstrated by cross-sectional echocardiography from the subcostal position.
From a subcostal position, the whole ventricle can be imaged in the majority of small children, but only very occasionally in older children.
Subcostal coronal views (using anterior angulation) can also be used in infancy.
Then the standard subcostal four-chamber view was obtained to identify the atrial septum and both the atrioventricular valves.
Echocardiographic diagnosis was established using the short-axis view of the abdomen and multiples cuts from subcostal and apical views.
All these abnormalities can be identified during infancy from subcostal paracoronal sections taken anterior to the atrioventricular valves.
