Abstract

ObjectiveSecond pregnancies are usually less complicated than first pregnancies, and have a better outcome in terms of fetal growth. We studied a group of women with heart disease to assess whether their second pregnancy was less complicated and resulted in a larger baby.DesignRetrospective case control study.SettingTertiary referral academic obstetric unit.PopulationFirst and second pregnancies in 77 women with congenital and acquired heart disease and in 154 control women were identified.MethodsData were collected from medical and obstetric records.Main outcome measuresCardiac complications, obstetric complications, intra‐partum events, birthweight and perinatal complications.ResultsThe rate of obstetric complication was greater in first pregnancies in both the heart disease and the control groups (38% versus 26%, cf. 20% versus 17%). In the heart disease group, the rate of cardiac complications was similar in first and second pregnancies (9% versus 6%). Overall, significantly more perinatal complications were seen in the heart disease group, with no significant difference between first and second pregnancies (36% versus 27%, cf. 14% versus 12%). Median birthweight was significantly higher in second pregnancies in the control group (3308 versus 3519 g P < 0.001), but not significantly different between pregnancies in the heart disease group (3014 versus 3133 g, P = 0.19).ConclusionsThis case control study demonstrates that women with mild to moderate heart disease have similar pregnancy outcomes in consecutive pregnancies. However, while the median birthweight was higher in the control second pregnancies, it was not increased in the women with heart disease.Tweetable abstractA study of women with heart disease to assess whether their second pregnancy was less complicated.
