Methods
This study retrospectively analyzed the clinical data of 999 patients
with CHD who were admitted to our hospital between January 2010 and
December 2019 (Figure 1 ). Patients were divided into surgical
and non-surgical group, and the differences of obstetric events,
cardiovascular events, delivery procedure, fetal events, and other
events between the two groups were compared. Obstetric events included
hypertension during pregnancy, placenta previa, gestational diabetes,
placental abruption, hemorrhage, pre-term delivery, and preeclampsia.
Cardiovascular complications included heart failure (HF), arrhythmias,
and thromboembolic events such as stroke and pulmonary embolism.
Delivery procedure included cesarean section (CS), artificial rupture of
the membranes, and induction. Fetal events included fetal distress,
fetal growth restriction, fetal malformation, fetal death or stillbirth,
and low birth weight (LBW). Moreover, there were other events like
pulmonary hypertension (PH), Eisenmenger syndrome (ES), death,
respiratory diseases, and systemic hypertension. Meanwhile, all patients
and their offspring were followed up by telephone.
