Feasibility of constructing a screening-evaluating-intervention system of congenital heart disease in Changzhou city

Abstract

Objective To investigate the prevalence and the distribution of congenital heart disease(CHD) in Changzhou city.The clinical data of 106 CHD infants were reviewed, so as to provide some evidence for making CHD screening-evaluating-intervention system. Methods All infants(16 070 cases) born in Changzhou Maternal and Child Health Hospital from May 1st 2011 to Apr.30th 2013 were screened for CHD.The infants with CHD were followed up for one year periodically after discharge. Results One hundred and seventeen infants were screened positive, and 106 cases of them were diagnosed as CHD, and the detectable rate was 6.60‰.The top three incidence was VSD (2.18‰, 35/16 070 cases), PDA(1.74‰, 28/16 070 cases) and ASD(1.06‰, 17/16 070 cases). Among them, 81 cases were detected as cardiac souffle, and 48 cases as abnormal pulse oximetry.In 106 cases, 97 cases were followed up and 9 cases did not receive follow-up.The close ratio were higher in ASD, PDA, VSD, which was 76.47%, 64.29%, 62.86%.The size of gap had an effect on close ratio, small gap of VSD, ASD and premature PDA were higher and medium and large gap and full-term infants were lower.Some serious type of CHD infants received operations, and others were still followed up. Conclusion The detectable rate of CHD among infants was identical to the average level of whole country.The follow-up study may improve the quality of the survival of CHD infants, and it is feasible to construct a system of screening-evaluating-intervention systcm of CHD.
