TEE - transgastric view centered on the right ventricle and past its outflow tract.
RV: right ventricle, LV: left ventricle, PA: pulmonary artery trunk.
This view is obtained from the short-axis curve of the left ventricle (film 9), by slightly turning the probe so as to center on the right ventricle, then by positioning the multiplane probe between 0 and 90°. This visualizes the outflow tract of the right ventricle as well as the trunk of the pulmonary artery.
From this view, using pulsed Doppler with the probe positioned upstream of the pulmonary valve, it is possible to assess variations in velocity of right ventricular ejection during ventilation. As with the short-axis parasternal view in TTE (film 5), one can also measure the stroke volume of the right ventricle.
