To visualize the pulmonic stenosis (PI) jet utilize the parasternal RV outflow view, parasternal short-axis and subcostal view. The PS flow jet occurs in systole, as blood moves through the pulmonic valve into the pulmonary artery.

This off-axis parasternal short axis view of a newborn infant shows a pulmonic stenosis flow jet in the pulmonary artery in systole using an enhanced velocity map. The blue color indicates the PS flow jet moving away from the transducer. Yellow hues indicate aliased flow while the turbulent flow has a characteristic mosaic of blue and yellow. The red color distal to the valve is the result of blood swirling in the pulmonary artery. The blue in the center of the picture represents normal blood flow in the aorta.
