[Pulmonary valvulotomy or valvulectomy with simple clamping of the vena cava in infants and young children].

In infants and young children pulmonary valvulotomy or valvulectomy under simple clamping of the vena cava is the treatment of choice for pulmonary valve stenosis with normal interventricular septum. The technique, performed without cardiopulmonary bypass, is described. In 40 patients operated upon, the peri-operative mortality was 10% and short-term clinical results were satisfactory.
