SUMMARY
EVALUATE THE RESULTS SHORT TERM FOLLOW-UP OF PERCUTANEOUS
BALLOON VALVULOPLASTY FOR PULMONARY VALVE STENOSIS
IN CHIDREN FROM 0  24 MONTHS
Background: pulmonary valve stenosis relieved by balloon dilatation during cardiac
catheterisation is the treatment of choice. The results of immediate and short term follow-up of
balloon dilatation of the pulmonary valve have been well documented.
Objective: to evaluate the results short term follow-up of balloon dilatation of the pulmonary
valve in children from 0  24 months in National Hospital of Pediatrics, Vietnam.
Design: Prospective study
Methods: Between Jan 2009 to Dec 2010 we performed percutaneous balloon valvuloplasty
for pulmonary valve stenosis in 38 children with aged between 0 month and 24 months, mean
(±SD) 8.84 ± 6.15 months.All patients were follow-up before and after balloon valvuloplasty by
Doppler echocardigraphy.
Results: After balloon valvuloplasty, in Echo the systolic pressure gradient across the
pulmonary vale decresed from 84.24 ± 28.92 mmHg to 20.50 ± 16.35 mmHg (p<0.001) and the
diameter of the pulmonary valve orifice increased from 3.71 ± 1.12 mm to 8.56 ± 2.77 mm
(p<0.05). In catheterization the systolic pressure gradient across the pulmonary vale decresed
from 72.55 ± 27.30 mmHg to 14.68 ± 11.48 mmHg (p<0.001). There was one patient restenosis.
Conclusions: Echocardiographic is usefully for diagnosis and classification of pulmonary
valve stenosis. The results of short term follow-up of balloon dilatation of the pulmanary valve
in children from 0 to 24 months are excellent.
