This week we discuss 2 papers on different areas of congenital cardiology. The first is a recent Brazilian report on Zika Virus Syndrome and associations with congenital heart disease. The second is a recent report by the team at Children's Hospital of Philadelphia on exposure to plastic neurotoxicants found in many common medical devices. Do these plastic substances have an impact on neurodevelopmental outcomes? Dr. William Gaynor of CHOP speaks with us about this very important and somewhat troubling work.
