Key result
Pregnant women with moderate (n=1277) or severe (n=251) congenital heart disease experienced higher rates of complications, mortality, and ICU admissions compared to 2,467,589 women without CHD.
Why the study?
Women with congenital heart disease are increasingly surviving into adulthood and undergoing pregnancy.
Does moderate or severe congenital heart disease increase complications, mortality, and healthcare utilization in pregnant women undergoing delivery?
Observational (n=2,469,117)
Yes
Does moderate or severe congenital heart disease increase complications, mortality, and healthcare utilization in pregnant women undergoing delivery?
Pregnant women with moderate or severe congenital heart disease face higher risks of complications, mortality, and healthcare utilization during delivery compared to those without CHD.
May warrant closer peripartum monitoring in moderate-severe CHD; leaves open whether targeted interventions improve outcomes.
Background: Women with congenital heart disease (CHD) are surviving into adulthood, with more undergoing pregnancy. Methods: Retrospective review of the Vizient database from 2017-2019 for women 15-44 years old with moderate, severe or no CHD and vaginal delivery or caesarean section. Demographics, hospital outcomes and costs were compared. Results: There were 2,469,117 admissions: 2,467,589 with no CHD, 1277 with moderate and 251 with severe CHD. Both CHD groups were younger than no CHD, there were fewer white race/ethnicity in the no CHD group and more women with Medicare in both CHD groups compared to no CHD. With increasing CHD severity there was an increase in length of stay, ICU admission rates and costs. There were also higher rates of complications, mortality and caesarean section in the CHD groups. Conclusion: Pregnant women with CHD have more problematic pregnancies and understanding this impact is important to improve management and decrease healthcare utilization.

Kops et al. (2021) conducted an observational in Congenital heart disease in pregnancy (n=2,469,117). Moderate or severe congenital heart disease vs. No congenital heart disease was evaluated on Hospital outcomes and costs (length of stay, ICU admission rates, complications, mortality, caesarean section). Pregnant women with moderate (n=1277) or severe (n=251) congenital heart disease experienced higher rates of complications, mortality, and ICU admissions compared to 2,467,589 women without CHD.
