  • Pulmonary Stenosis
    • Thickened pulmonary valve visualized with minimal systolic excursion
    • Trivial amount of antegrade flow across the pulmonary valve (narrow blue color Doppler jet)
    • Severely hypertrophied right ventricle

  • Pulmonary Stenosis
    • Thickened pulmonary valve with trivial antegrade flow across the pulmonary valve
    • Retrograde (left to right) flow noted from PDA into main pulmonary artery
