Between 1981 and 1992, 22 children from 1 to 15 years of age have undergone cardiac valve replacements at National medical center. The patients were composed of 14 males and 8 females and 7 patients had congenital heart disease and 15 patients had rheumatic heart disease. Three of these 15 patients have had second valve replacement due to prosthetic valve failure[PVF]. Single valve replacement were 20[Aortic 3 cases, Mitral 17 cases] and double valve replacments were 2. The overall mortality was 22.7 %. Actuarial survival rate was 77.28 $pm$ 8.92 % and Complication free rate was 67.68$pm$15.56%. The pediatric valve replacements can now be performed at a low operative risk although various problems are still remained and the choice of valve is prosthetic valve mainly due to its durability at the present time.
