After years of medical specialty societies and patients advocating for universal screening of critical congenital heart defects (CCHD) in newborns, pulse oximetry testing has finally become routine in the majority of states. Since 2012, 30 states have adopted CCHD screening laws and 39 states will have laws requiring newborn screening for CCHD using the pulse oximetry test by July 1, 2014. Passing CCHD screening legislation is one of the College's state advocacy priorities and the ACC is continually working with local ACC Chapters, the Adult Congenital and Pediatric Cardiology Section, and partners such as Mended Hearts and Mended Little Hearts to ensure the voice of CCHD patients and caregivers is heard on the state level as well as Capitol Hill.
