Identify the left ventricle (circular), right ventricle (crescent-shaped), and surrounding pericardium (Fig. 24.39). ++ FIGURE 24.38 Parasternal Short-Axis View. Place the transducer in the fourth or fifth left parasternal intercostal space in a line connecting the left clavicle/shoulder and the right hip, with the transducer rotated 90 degrees clockwise from the parasternal long-axis view.

The left ventricle (circular) and right ventricle (crescent-shaped) and surrounding pericardium are seen. The papillary muscles are seen in cross-section. (Illustration contributor: Robinson M.

Dilated right ventricle: The right ventricle is normally a crescent-shaped structure. A rounded, dilated right ventricle that deforms the rounded left ventricle (creating an “OD” sign) suggests elevated right-sided pressures, as seen with pulmonary emboli and severe pulmonary hypertension (Fig. 24.40). ++ FIGURE 24.40 Parasternal Short Axis.

Visualization of the papillary muscles should ensure a true transverse section through the left ventricle, and provides a prime location for the evaluation of left ventricular contraction and motion.
