Introduction
Due to improvement in the treatment of congenital heart disease (CHD),
most women with CHD now survive to adulthood, get married and try
conception, and concomitant CHD is thought to increase perinatal
risk1-3. Traditional thinking that cardiac surgery
prior to pregnancy improves maternal and fetal outcome in patients with
CHD. However, there are a few relevant studies, large samples were
less4-6. Moreover, whether and when CHD parturients
need surgery still needs to be discussed.
In 2007, Beijing Anzhen Hospital affiliated to Capital Medical
University, was designated as the only referral and consultation center
of pregnancy with heart diseases in Beijing. Almost all pregnant women
with CHD visited Beijing Anzhen Hospital for consultation, treatment,
and gave birth to children, which has laid the research foundation for
this study.
In the previous study of our team, it was had determined that the risk
of maternal complications during pregnancy with CHD was higher than that
without CHD. In this study, we will further investigate whether it is
better to have surgery before pregnancy or after surgery for pregnant
women with CHD.
