Regression of valvular pulmonary stenosis.
Eight patients with mild to moderate valvular pulmonary stenosis underwent serial physiological studies before surgical intervention. Average pulmonary valve area at the initial study was 0.59 cm.2 and at the second study (average 7.8 years later) was 1.09 cm.2, resulting in an average increase of 0.49 cm.2 (p greater than 0.05). In normal subjects during early years the pulmonary valve area in...
متن کاملPulmonary valvotomv PULMONARY VALVULAR STENOSIS
Twenty children with pulmonary valvular stenosis were studied by cardiac catheterization both at rest and during submaximal supine exercise, prior to and following pulmonary valvotomy. The resting and exercise states were comparable preoperatively and postoperatively since cardiac output, heart rate, A V 02 difference and oxygen consumption were similar. Evidence of improved cardiac function wa...
متن کاملPulmonary valvular stenosis.
OBSTRUCTION to the outflow of blood from the right ventricle may occur as a result of congenital stenosis of the pulmonary valve, of the infundibulum, or of the supravalvular area. These all result in a fixed constriction of the lumen of the involved region. Recently, considerable interest has been focused upon a more dynamic type of infundibular obstruction that occurs in a number of patients ...

متن کاملValvulotomy for pulmonary valvular stenosis.
An earlier paper, reporting 3 successful cases (Brock, 1948), showed the feasibility of valvulotomy for the relief of pulmonary valvular stenosis. The present paper deals with our clinical and operative experience in 33 cases-a number large enough to allow certain conclusions to be drawn. Of the 33 patients submitted to operation, 18 had pure pulmonary stenosis, by which we mean pulmonary valvu...
