Fig. 6.31  Subxiphoid ventricular short-axis view

2.27.1\ Scanning Methods

The patient lies supine or on the left-anterior position. The transducer is placed in the subxiphoid (subcostal) area and rotated 45° clockwise on the base of subcostal four-chamber view.

2.27.2\ Section Structure

Transverse sections of right and left ventricular short axis are shown in this view. By manipulating the sectoral scanning, short-axis views of mitral valve, chordae tendineae, papillary muscles, and apex at different levels can be obtained, respectively.

2.27.3\ Measuring Method and Normal Value

Left and right ventricle diameters measured at mitral chordae tendineae level in diastole are 40 ± 14 and 30 ± 12 mm.

2.27.4\ The Clinical Application Value

If satisfactory images cannot be obtained by a precordial region scan due to too much air in the lung, the subcostal view can be used, as a supplementary scan, to show the ventricular structures.
