Racial Disparities in Outcomes of Delivery and Cardiac Complications Among Pregnant Women with Congenital Heart Disease

Abstract

Advances in cardiology have led to improved survival among patients with congenital heart disease (CHD). Racial disparities in cardiovascular and maternal outcomes are well known and are likely to be more profound among pregnant women with CHD. Using the 2001 to 2018 National Inpatient Sample, we identified all hospitalizations for delivery among women ≥ 18 years of age with CHD. Unadjusted and adjusted between-race differences in adverse maternal cardiovascular, obstetric, and fetal events were assessed using logistic regression models. During the study period, we identified 52,711 hospitalizations for delivery among women with concomitant CHD. Of these, 66%, 11%, and 16% were White, Black, and Hispanic, respectively. Obstetric complications and fetal adverse events were higher among Blacks compared to Whites and Hispanics (44% vs. 33% vs. 37%, p
