Mechanical valve replacement in children with heart valve diseases / 中南大学学报(医学版)

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.@*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.
