AbstractEmergency cesarean delivery in patients with heart failure increases maternal and fetal mortality. The present study aimed to identify the relationship between the use of anesthesia for delivery and progressive cardiac deterioration in women with dilated cardiomyopathy (DCM) and to examine its implications on maternal and fetal outcomes. Twenty-nine pregnancies in 25 women with DCM from the National Cerebral and Cardiovascular Center Hospital (Suita, Japan) were included in this retrospective longitudinal study. Fourteen of the patients (48.3%) delivered via cesarean section. Among these, 4 patients (13.8%) experienced heart failure within 42 days of delivery. The indication for cesarean delivery was heart failure in 3 patients and induction failure in 1 patient. The types of anesthesia used for these patients included general (n = 1), combined spinal-epidural (n = 2), and epidural (n = 1). Two of these cesarean deliveries were performed preterm. The left ventricular ejection fraction of patients with heart failure was ≤ 35% before 34 weeks gestation. Among the 25 patients without heart failure, 2 exhibited a left ventricular ejection fraction of ≤ 35% before 34 weeks gestation. Meanwhile, the types of anesthesia used for remaining 10 patients who did not experience heart failure included general (n = 1), combined spinal-epidural (n = 8), and epidural (n = 1). The rate of general anesthesia was 25% in patients who experienced heart failure and 4% in others. There was no incidence of maternal or fetal death. A preterm anesthetic evaluation may be warranted to optimize anesthetic management when the ejection fraction decreases to ≤ 35% before 34 weeks gestation in patients with DCM.Copyright © 2023 the Author(s).
