title: [Prevalence study of congenital heart disease in children aged 0-2 in Zhejiang Province].
abstract: OBJECTIVE
  To find out the prevalence rate of Congenital Heart Disease (CHD) among infants and toddlers.
  
  
  METHODS
  Heart auscultation and echocardiography examination on children aged 0-2 were examined in 13 cities (or counties) in Zhejing province.
  
  
  RESULTS
  Findings showed that the prevalence rate in children aged 0-2 was 3.72/1000. The prevalence rates of CHD were quite different among age groups with the highest (5.54/1000) in age group 0, followed by 3.36/1000 in age group 1 and lowest (2.66/1000) in age group 2. No significant difference of prevalence rates was found between different sex. Ventricular septal defects (59.4%) was noticed as the most common lesion.
  
  
  CONCLUSIONS
  The evidence indicated that CHD is one of the most important problems of public health in China. Preventing its occurrence by conducting CHD surveillance and its etiologic research will have great significance for enhancing the qualities of life of children.
