  • Data are presented as n (%) or median (range).

  • 1 PS, pre-echo peak RVOT velocity/gradient ≥50 mm Hg.

  • 2 PR, pre-echo peak RVOT velocity/gradient ˂50 mm Hg.

  • 3 Mixed lesion, mild stenosis and more than moderate insufficiency.

  • Bold numbers are statistical significant values.

  • PA, pulmonary artery; PS, pulmonary stenosis; RV, right ventricle; RVOT, right ventricular outflow tract; TGA, transposition of the great arteries; VSD, ventricular septal defect.
