Case 19

Two-dimensional Echocardiograms

Right parasternal cross-sectional view at the base

The aorta (AO), left atrium (LA), and body of the right ventricle (RV) are labeled. The arrow points to a structure in the right ventricular outflow tract.

Right parasternal cross-sectional view taken at the level of the ventricles

The right ventricle (RV) and left ventricle (LV) are labeled. The arrows point to the ventral border of the same structure identified in the image above.

Right parasternal cross-sectional view taken at the level of the pulmonary artery branches

The top of the same structure identified in the two previous echocardiograms is seen in the main pulmonary artery and at least partially occluding the right caudal lobar pulmonary artery branch (RPA). AO = aorta; RA = right atrium.
