    BackgroundAdvances in medicine have enabled more patients with congenital heart disease (CHD) to become pregnant. However, these patients face significant challenges during the peripartum period. Current peripartum anesthesia guidelines for CHD patients mainly rely on case reports and small series.MethodsIn this retrospective study at a high-volume tertiary care center, we analyzed peripartum anesthetic approaches, postpartum hemorrhage (PPH) incidence, and maternal outcomes in CHD patients stratified by the modified World Health Organization (mWHO) classification.ResultsAmong 85 473 deliveries between 2009 and 2023, 409 occurred in 282 patients with CHD. Cesarean deliveries were significantly more frequent in mWHO class III, p=0.005. Labor epidural analgesia was the most common analgesic modality for vaginal deliveries (epidural rate was 71.1% with no differences between mWHO classes). Anesthesia management for cesarean deliveries varied significantly by class p<0.001. While spinal anesthesia was predominant in classes I and II, combined spinal-epidural anesthesia was more common in class III. PPH incidence was 6.4%, with no significant difference across classes, and no association was found between mWHO class severity and PPH risk (OR 0.97; 95% CI; 0.93 to 1.02, p=0.2). Higher mWHO classes correlated with significantly higher intensive care unit (ICU) admission rates, longer hospital stays, and one-year cardiac hospitalizations.ConclusionIn this retrospective study on the peripartum anesthetic management and outcomes of CHD patients stratified by mWHO class, cases with greater mWHO class were more likely to deliver preterm, by cesarean delivery, with a combined spinal-epidural anesthetic and an arterial line placement for that cesarean delivery. They overall had a longer hospital stay and were more likely to be admitted to the ICU. However, the overall risk of PPH did not increase with mWHO class severity.Copyright © 2024 Elsevier Ltd.
