title: [Mechanical valve replacement in children with heart valve diseases].
abstract: OBJECTIVE
  To determine the surgical point and technique of artificial mechanical valve replacement in children with heart valve diseases.
  
  
  METHODS
  From Jan. 1989 to Oct. 2005, 63 children under 15 years received mechanical cardiac valve replacement with cardiopulmonary bypass (CPB).
  
  
  RESULTS
  The valve replacement included aortic valve replacement in 20 children, mitral valve replacement in 37 children and combined aortic valve and mitral valve replacement in 6 children.
  
  
  CONCLUSIONS
  The operation mortality was 7.94%(5/63). The follow-up periods were from 4 months to 204 months. The late mortality was 10.34%(6/58). All the other children were in NYHA class I - II. The operation mortality of children with heart valve replacement is higher than that of adults, but it was very effective.
