Congenital Heart Disease (CHD), the most common congenital birth defect, has long been known as one of the main causes of death in the first year of life worldwide. Some 90% are denied treatment or receive suboptimal care, and up to 80% of cases are not diagnosed until advanced or irreversible stages of heart failure.  Without treatment, 1 in 3 babies will die within their first month. Access to care for these children is not equal for all, depending on the countries of origin and regions of the world. Tremendous amount of work remains to be done to improve availability of diagnosis, therapeutic interventions and critical care for children with congenital heart defects.
