Subcostal Short Axis

Transducer Position: Rotate the transducer clockwise from the 4 chamber position to about 1-2 o' clock. Tilt the probe head to move from base to apex.  In a patient with ideal windows you can get images very similar to the parasternal short axis.

The views here are similar to the parasternal short axis except that we are imaging from a different position. The RV is on the right side in this view. 

This is a short axis level at the base showing the aortic valve (center), tricuspid valve (top) and pulmonic valve level (just to the right of the aortic valve). You can be sure these are subcostal views because the liver is clearly visible. 

This is a view at the mid papillary muscle level and is very similar to the parasternal short axis but the RV is off to the right in this view.
