Congenital heart disease (CHD) is the most common birth defect and is increasingly diagnosed prenatally. Mothers describe their prenatal experiences as highly stressful and traumatic after a diagnosis of CHD. Maternal stress during pregnancy exerts a powerful influence on birth outcomes and developmental trajectories, particularly for children in underserved populations. In partnership with diverse parent and clinician stakeholders, our team designed HEARTPrep, an innovative, virtually-delivered psychosocial intervention for mothers expecting a baby with CHD. This project will pilot HEARTPrep with mothers expecting a baby with CHD to obtain preliminary data for a larger future trial. This intervention has the potential to improve emotional wellbeing in mothers expecting a baby with CHD, thereby altering developmental trajectories for this large population of children.

Congenital heart disease (CHD) is the most common birth defect and is increasingly diagnosed prenatally. Mothers describe their prenatal experiences as highly stressful and traumatic after a diagnosis of CHD. Maternal stress during pregnancy exerts a powerful influence on birth outcomes and developmental trajectories, particularly for children in underserved populations. Targeted efforts to mitigate impacts of maternal stress for this highly vulnerable population are lacking. In partnership with diverse parent and clinician stakeholders, the investigators designed HEARTPrep, an innovative, virtually-delivered psychosocial intervention for mothers expecting a baby with CHD. HEARTPrep will be delivered through the Nemours App, an accessible tool for telehealth and patient education. The investigators aim to determine whether HEARTPrep modules produce clinically significant improvements on outcomes in mothers expecting a baby with CHD (Proof-of-Concept). This program of research has the potential to improve emotional wellbeing in mothers expecting a baby with CHD, thereby altering developmental trajectories for this large population of children.
