Figure legends:
Figure 1. How to perform the evaluation of pulmonary valve and right
ventricular outflow tract: A, position to perform echocardiogram by
subcostal view in prone position, with a pillow placed under left
hemithorax (light blue). B, the echocardiogram transducer was placed
under the patient in the left subcostal position and orientation index
marker pointing towards the patient´s left shoulder to view the 4
cardiac chambers. C, subtle upward movement of the transducer tail to
view the pulmonary valve and a small portion of the RVOT. D,
counter-clockwise rotation of the transducer to view the short axis of
the RVOT. Abbreviations - A: Aorta. AV: aortic valve. LA: left atrium.
LV: left ventricle. PA: pulmonary artery. PV: pulmonary valve. RA: right
atrium. RV: right ventricle. RVOT: right ventricle outflow tract.

ventricular outflow tract. B, continuous Doppler of Pulmonary valve. C,
short axis of the right ventricular outflow tract. D, colour Doppler of
short axis of the right ventricular outflow tract. E, Continuous Doppler
of Pulmonary valve. F, Pulsed Doppler at right ventricular outflow tract
level.
