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.
Conclusion:
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.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
