In this issue of JAMA Cardiology, Lytzen et al¹ report the findings of their study on prenatal screening (PNS) for congenital heart disease (CHD) in Denmark.¹ Notably, they find that with increased training and experience, technicians were able to identify roughly 70% of cases of major CHD in fetuses. Their findings are remarkable; however, the data also raise broader concerns.
