Figure 1: Comparison of parameters before and after balloon dilation between successful and unsuccessful subgroups in all four groups. (a) Diameter differences of stenotic segments before and after balloon dilation between successful and unsuccessful subgroups in all four groups. (b) Pressure differences over stenotic segments before and after balloon dilation between successful and unsuccessful subgroups in all four groups. (c) RV/AO pressure ratio before and after balloon dilation between successful and unsuccessful subgroups in all four groups. PVS: Pulmonary valve stenosis; PAS: Pulmonary artery stenosis; SVPS: Supravalvular pulmonary stenosis; VCS: Valved conduit stenosis; RV: Right ventricle; AO: Aorta.
