[Pulmonary valve stenosis. The medical solution].

Pulmonary valvular stenosis had been diagnosed since infancy in a 3 year-old girl. Cyanotic episodes occurring when the child cried led to the decision to remove the stenosis, whose gradient was 58 mmHg. Transluminal dilatation through the femoral vein, after premedication and local anesthesia induced a decrease of the gradient to 18 mmHg with a good angiographic result. This technique, which may be used in numerous types of pulmonary stenosis, allowed avoidance of the disadvantages of surgery under general anesthesia with median sternotomy and cardiopulmonary by-pass.
