Abstract
During the period of 2 years, between January 1986 and December 1987, 36 patients, aged 2 years to 18 years, with congenital pulmonary valve stenosis(PVS) (with peak systolic transvalvar gradient over 30 mmHg) underwent percutaneous transluminal balloon valvuloplasty(TBV) at Sejong General Hospital m Korea. Of a group of 36 patients, 26 were treated successfully by the conventional balloon valve dilatation technique, and 6 were treated by twin balloon dilatation technique, while remaining 4 required gradual dilatation technique. All patients had hemodynamic evidence of relief of PVS immediately after TBV. The right ventricular systolic pressure and transvalvar peak systolic gradient decreased significantly immedi- ately after the procedure in all 36 patients (92.39±43.70 vs 51.19±26.03 mmHg, p<0.005, and 68.81 ± 42.50 vs 21.83 ±16.72 mmHg, p< 0.005). Follow-up CW Doppler data revealed, this decreased pressure gradient have maintained or further decreased in all 32 follow-up patients, exept one case with dyspfhstic valve, with mean late residual pressure gradient of 21.14 ±10.52 mmHg. In conclusion, these results support the belief that TBV is effective chronically in the relief of PVS and may be considered the treatment of choice in classic congenital pulmonary valve stenosis with mobile doming valve.
