A Study of Pregnancy Outcomes in Congenital Heart Disease (POACHD)

March 17, 2026 updated by: Alexander C. Egbe, Mayo Clinic

Pregnancy Outcomes in Patients With Adult Congenital Heart Disease

The purpose of this study is to determine if a biomarker assay obtained peripartum (1st-3rd trimester and post-partum) in patients with adult congenital heart disease can predict future risk of cardiovascular adverse events and determine if temporal changes in biomarkers levels throughout the peripartum period can provide a better risk prediction compared to samples taken at a single time-point.
