Use of balloon dilatation to treat supravalvar pulmonary stenosis developing after anatomical correction for complete transposition.
Eight balloon dilatations were performed in five patients (aged from 10 to 37 months) in whom supravalvar pulmonary stenosis developed after anatomical correction for complete transposition. The ratio of the maximum diameter of the inflated balloon to the narrowest pulmonary arterial diameter varied from 1.6 to 3.3. In three patients with an initial ratio of less than or equal to 2 dilatation w...
متن کاملComplete heart block after balloon dilatation for congenital pulmonary stenosis.
Permanent complete heart block developed in a five year old child during balloon dilatation for pulmonary valve stenosis. Damage to the atrioventricular node by pressure from the inflated balloon may have caused the conduction defect.
متن کاملDecreased incidence of supravalvar pulmonary stenosis after arterial switch operation.
BACKGROUND Supravalvar pulmonary stenosis (SVPS) is frequently observed after arterial switch. Traditionally the coronary arteries are removed from the neopulmonic root by excising the entire sinus of Valsalva. As a result, reconstruction of the neopulmonic root requires a pericardial patch encompassing two-thirds of the anastomosis between the neopulmonic root and pulmonary artery. We present ...
متن کاملVariability of the Doppler gradient in pulmonary valve stenosis before and after balloon dilatation.
The variability of the valve gradient measured by Doppler in pulmonary stenosis was compared with the variability of the gradient measured at catheterisation in 42 infants and children undergoing catheterisation with a view to balloon dilatation of the pulmonary valve. The maximum value measured by Doppler when the patient was unsedated was significantly higher than that measured when the patie...
متن کاملBalloon dilatation of complete obstruction of the superior vena cava after Mustard operation for transposition of great arteries.
Balloon dilatation was successfully performed in two patients with complete obstruction of the superior vena cava baffle junction after a Mustard operation for transposition of the great arteries. Evidence for complete relief of obstruction in the first patient, aged 4 years, was obtained by angiography, which showed improved calibre at the site of obstruction and improved haemodynamic pressure...
