(562) Impact of interdisciplinary clinic on delivery mode and gestational age in adult congenital heart disease

Wednesday, February 11, 2026
3:30 PM - 5:00 PM  
Objective:
Advances in care have enabled more patients with complex congenital heart disease to reach childbearing age. This study evaluated the impact of an interdisciplinary clinic model on maternal delivery outcomes in this population.

Study Design:
Retrospective cohort study of patients with adult congenital heart disease (ACHD) who delivered at a single institution before and after the implementation of a collaborative ACHD-Maternal-Fetal Medicine (MFM) clinic model in August 2019, focused on interdisciplinary clinic visits and delivery planning. Mode and gestational age of delivery for ACHD patients who delivered before (January 2008-December 2018) and after (January 2020-December 2024) utilizing the interdisciplinary clinic model were compared.

Results:

A total of 192 patients with ACHD were identified: 86 delivered before and 106 delivered after the establishment of the interdisciplinary clinic model. All patients (nulliparous and multiparous) were less likely to deliver vaginally prior to the implementation of the joint clinic model [pre/post 42.2% vs 60.0%, OR 0.48 (CI 0.25, 0.89)].  Nulliparous patients alone were also less likely to deliver vaginally prior to implementation of the joint clinic model [pre/post 10.8% vs 22.1%, OR 0.32 (95% CI 0.10, 0.96)] (Table 2). Rate of induction of labor for nulliparous patients was significantly lower prior to the joint clinic model [pre/post OR 0.09 (95% CI 0.02,0.34)]. No significant difference in gestational age of delivery was observed [pre/post 36.3wk vs 37.6wk]. No change in maternal postpartum cardiovascular complications was observed after the joint clinic model, represented as readmission within 6 weeks, postpartum ICU admission, or cardiovascular complication within 12 months.

Conclusion:

Implementation of an interdisciplinary ACHD-MFM clinic model was associated with higher likelihood of vaginal delivery among all patients and a higher likelihood of induction of labor for nulliparous patients.
