This document proposes a new international project called "Heaven Can Wait" to address critical congenital heart disease in developing countries. It involves establishing prenatal cardiac screening programs and transferring high-risk fetal-maternal pairs to centers in Europe for delivery and cardiac surgery. This aims to give neonates the best chance for treatment and survival, while also improving the efficacy of humanitarian cardiac organizations by providing them with prenatally detected cases. Though large-scale implementation faces challenges, the project envisions adding a new dimension to fetal and perinatal cardiology to help address the stark contrast in outcomes between developed and developing world contexts.
