Mode of delivery among women with maternal cardiac disease.

OBJECTIVE: To determine if maternal cardiac disease affects delivery mode and to investigate maternal morbidity. STUDY DESIGN: Retrospective cohort study performed using electronic medical record data. Primary outcome was mode of delivery; secondary outcomes included indication for cesarean delivery, and rates of severe maternal morbidity. RESULTS: Among 14,160 deliveries meeting inclusion criteria, 218 (1.5%) had maternal cardiac disease. Cesarean delivery was more common in women with maternal cardiac disease (adjusted odds ratio 1.63 [95% confidence interval 1.18-2.25]). Patients delivered by cesarean delivery in the setting of maternal cardiac disease had significantly higher rates of severe maternal morbidity, with a 24.38-fold higher adjusted odds of severe maternal morbidity (95% confidence interval: 10.56-54.3). CONCLUSION: While maternal cardiac disease was associated with increased risk of cesarean delivery, most were for obstetric indications. Additionally, cesarean delivery in the setting of maternal cardiac disease is associated with high rates of severe maternal morbidity.
