The probe is tilted so the that the right atrium (RA), tricuspid valve, and right ventricle (RV) are all visualized The left ventricle (LV) is posterior to the RV FIG 19.19 Parasternal long-axis view showing the right ventricular outflow tract (RVOT) obtained by tilting the probe anteriorly The left ventricle (LV), the infundibulum, the pulmonary valve, and the pulmonary trunk (PA) are all seen FIG 19.20 Parasternal short-axis view of the aortic valve Three leaflets can be seen, which are supported by left coronary (LCC), right coronary (RCC), and noncoronary (NCC) aortic sinuses FIG 19.21 Parasternal short-axis cut of the right ventricular outflow tract (RVOT) showing the pulmonary valve, the pulmonary trunk (PA), and the right and left pulmonary arteries (LPA, RPA) AO, Aorta
