Search for: [Abstract = "ely. After BPV, in all but one patient, a significant \(P<0.001\) reduction of RVSP, RVEDP \(right ventricular end\-diastolic pressure\), SPG \(systolic pressure gradient\), as well as an increase of PASP \(pulmonary artery systolic pressure\) were observed in Group 3. Double balloon procedures were required by a total of eight patients, including six from Group 1 and two from Group 2. The method was successful in all the children. In patients with dysplastic pulmonary valves, the ratio of balloon diameter to valve annulus was significantly higher \(P<0.002\) \(Group 1 – 1.4±0.3, Group 3 – 1.43±0.13\). In one Group 2 child, the immediate effect PBVP was good, but 5 years later, restenosis requiring a repeated intervention was diagnosed. In another patient from this group, the procedure was unsuccessful and surgery was necessary. The immediate PBVP result was good in all Group 3 patients. However, 7\/38 children \(18.4%\) were re\-catheterized in late follow\-up due to recurrent stenosis diagnosed by echocardiography. In four of these children, a repeated BVP was successfully performed\; two – with dysplastic form of the defect \- were referred to surgical correction and one was disqualified \(pulmonary systolic pressure gradient = 20 mmHg\). Five patients \(3.6%\) developed various complications, including one with a serious complication of a split balloon \(Balt BDC\) being lodged in the iliac"]
