Prevalence of maternal miscarriage in infants with congenital heart disease

Abstract

Congenital heart disease (CHD) is a specific and sometimes life-threatening disease for infants imposing great costs on the family and the community. In this regard, it is important to assess the risk factors for this problem. One of the most important risk factors for these disease mentioned in previous studies is a history of maternal miscarriage. Because of controversies in previous studies, more studies are needed to clarify. as an innovation in this study, we investigated the relationship of the history and frequency of maternal abortion between two groups of infants with cyanotic and non-cyanotic cardiac disorders. Materials and Methods: In this study, the files of 100 infants with CHD from April 2016 to March 2018 were reviewed. This study was performed by cross-sectional and a retrospective method. Incidence of maternal miscarriage in the two groups is evaluated and compared. Demographic data including infant age, parental occupation, place of residence (urban or rural), number of abortions, interval between last abortion from current pregnancy and maternal age at pregnancy were extracted as well. descriptive information of variables and their relationship with the dependent variables in the sample were analyzed. Results: In this study, 100 mothers with children with congenital heart disease were enrolled. the mean age of mothers was 28.73± 7.08. The average number of pregnancies in these mothers was 2.22 ± 1.25. we obsereved 19% of mothers had a history of previous miscarriages. The average number of abortions in these mothers was 0.71 ± 0.29 and the distance of the last abortion from recent pregnancy was 26.47 ± 23.54 months. According to the results, 37% were female and 63% were male. The mean age of the neonates was 10.77 ± 9.8 days.
