Primary outcomePrimary: Motor Scale of the Bayley Scales of Infant and Toddler Development-III — 90.0; 87.5; 88.7 score on a scale
Summary
Neurodevelopmental disability is now recognized as the most common long-term complication after cardiac surgery in neonates. Research studies have shown that progesterone is critical to the development of the brain and in a variety of clinical situations including brain injury can protect the brain.
The purpose of this research study is to determine whether progesterone administered during the 3rd trimester of pregnancy (24-39 weeks) to pregnant women protects the brain of unborn babies with CHD and improves their neurodevelopmental outcomes after heart surgery.
