title: [Valve replacement in children].
abstract: We report 27 children aged 2-14 years underwent valve replacement. Twelve patients underwent mitral valve replacement, 11 tricuspid valve replacement, and 4 aortic valve replacement. Of them, 16(59.3%) were associated with cardiac malformation, 23 were in NYHA functional class III and IV in preoperation. 13 patients required additional procedures. There were 3 hospital deaths (11.1%), 4 late deaths (16.6%), and 2 reoperation. Our experiment suggested that the greater type of mechanical valve be essential for valve replacement in children, but suture technique be modified for the children with small valvular ring. After replacement of mechanical valve, low concentration anticoagulation therapy is considered as a safe and reliable method.
