[Familial pulmonary stenosis: considerations on genetic aspects].

A family with 4 cases of pulmonary valvular stenosis with under-developed or normal right ventricle, is reported. The father and his three daughters were affected. In two of the girls, who were twins, a prenatal diagnosis was made using 2D-echo. The importance of genetic counseling and prenatal diagnosis in the families at risk are underlined.

Surgical treatment of congenital pulmonary stenosis due to dysplastic leaflets and small valve anulus.

Seven cases of pulmonary valve stenosis due to congenital dysplasia of the valvular apparatus have been corrected by patch-graft enlargement of the right ventricular outflow tract. The six surviving patients (85%) are now leading normal lives with good exercise tolerance. The satisfactory right ventricular performance, manifested by these subjects after the operation and in the long-term follow-up, supports the validity of the procedure in the presence of a normal right ventricle and tricuspid valve.

Pulmonary artery tears following balloon valvotomy for pulmonary stenosis.

Tears involving the anterior supravalvar annulus developed in 2 children and an infant following percutaneous balloon pulmonary valvotomy using oversized balloons. The 3 patients had angiographic features of three different types of stenotic valves: usual pulmonary valve stenosis in 1, a form of dysplastic pulmonary valve with supravalvar narrowing in a second, and a doming valve in a neonate. All had a successful reduction in right ventricular outflow tract gradient following the procedure. The pulmonary arterial tears were not associated with balloon rupture or clinical symptoms. It is postulated that the relative deficiency of elastic fibers in the supravalvar commissure makes this site relatively vulnerable to intimal tearing.
