Tiny Hearts Project is a US-based nonprofit organization on a mission to increase the prenatal detection rate of congenital heart disease by training clinicians in the use of evidence-based techniques for fetal cardiac screening. We envision a future when all sonographers performing fetal imaging are proficient in standardized cardiac screening, all infants with significant congenital heart disease are recognized during pregnancy, and these vulnerable infants, their mothers and families receive the best possible care at just the right time.
