Chest X\-ray showed that an increasing degree of PVS was accompanied by an increasing cardiothoracic ratio \(↑CTR\) and lobulated contour of the main pulmonary artery \(↑LCMPA\) – Group 1\: ↑CTR – 17.2% and ↑LCMPA – 13.8%, Group 2 \- ↑CTR – 31.7% and ↑LCMPA – 46.3%, Group 3 \- ↑CTR – 57.9% and ↑LCMPA – 63.2%, As it followed from the analysis of echocardiographic results, the majority of patients \(92.4%\) demonstrated a typical form of PVS, while the dysplastic form was observed in 10 children only \(7.3%\) \(4\/41 Group 2 and 6\/38 Group 3 patients, with the highest degree of stenosis\). The most common finding \(67.7%\) was a three\-leaflet form of PV, but in approximately 20% of pts the structure of the defect could not have been determined. Pulmonary valve insufficiency \(PVI\) >IIo and subvalvular pulmonary stenosis \(SVPS\) were seen infrequently \(3\/137 and 7\/137, respectively\). The incidence of SVPS slightly increased with an increasing PVS degree. No statistical significance was noted in SVPS \(P = 0.07\) and PVI \(P = 0.07\) incidence in particular groups. However, tricuspid valve insufficiency was found to occur significantly more commonly in Group 3 \(9\/38\) as compared to Group 1 \(0\/58\) and Group 2 \(3\/41\) \(P<0.002\). The analysis of selected parameters as assessed by echocardiography vs. angiocardiography showed \(all values represented as mean\)\: \- the respective"]
