title: [Congenital aortic valve stenosis treated by dilatation. Apropos of a case with hemodynamic control 12 months later].
abstract: Intraluminal dilatation of congenital aortic valve stenosis was attempted in a 14-year old boy. Significant improvement was obtained, with a fall in transaortic gradient from 80 to 30 mmHg. A control haemodynamic examination performed 12 months later confirmed that the result was stable; there was no aortic leakage, and myocardial hypertrophy had begun to regress at echocardiography. This case is of interest in that dilatation is less costly than surgical commissurotomy. However, this technique cannot be widely used until satisfactory long-term results have been demonstrated in a large population of children.
