Grant: Doctoral Research Award : Priority Announcement - Global Health under IPPH

Prenatal detection of congenital heart defects (CHDs) is crucial for preparing for the birth of children with specific medical needs. However, in Quebec, only 66% of severe CHDs are detected before birth. This PhD project aims to compare the health outcomes of children whose CHD was detected before birth with those whose condition was discovered afterward. Using a large database covering more than 1.2 million mother-child pairs and incorporating information on diagnoses, cardiac interventions, hospitalizations, and mortality, we will seek to determine whether early detection improves survival and reduces postnatal complications. The findings of this research will help inform future parents about the potential health trajectory of their child and assist healthcare professionals in improving prenatal screening policies and care. This project stands out for its use of comprehensive data covering 15 years of follow-up and a rigorous analysis of the various factors that influence health outcomes in children with CHDs. Ultimately, this study could transform clinical practices and offer new hope to affected families.
