2D TTE from various parasternal views showing right ventricular outflow tract (RVOT) measurements

Measurement of right ventricular outflow tract (RVOT) dimensions at the proximal or subvalvular level (RVOT-Prox) and at the distal or pulmonic valve (RVOT-Distal) in the (A) parasternal long-axis RVOT anterior portion view, (B) basal parasternal short-axis view, and (C) parasternal short-axis of pulmonary bifurcation view.

PA: pulmonary artery dimension between valve and the bifurcation point.
