[Valve prostheses in children].

The results of 20 medico-surgical teams were combined to give a total of 93 patients aged less than 14 years, with a total of 94 replacement valves. The intra-operative and subsequent mortality rate, the complications and the results have been analysed. The best results are found amongst the severe rheumatic valve disorders in older children, while the worst are amongst the valvular malformations in the infant.
