Data are presented as mean ± SD or mean (IQR). CPS, critical pulmonary stenosis; PAVmax, pulmonary artery velocity maximum; SD, standard deviation; TVG, transvalvular pulmonary gradient; IQR, interquartile range; TRV, tricuspid regurgitation velocity; TTG, transvalvular tricuspid gradient; RVSP, right ventricular systolic pressure; PASP, pulmonary artery systolic pressure; PPG, peak-to-peak gradients.
