More than 10% of critical heart defects in newborns were discovered after hospital discharge in 2009, according to a Massachusetts study. Nevertheless, such delayed diagnoses were down from 17.1% in 2004, primarily because of increased use of prenatal ultrasound and improved cardiac imaging in prenatal care, researchers wrote. Coarctation, pulmonary valve stenosis and tetralogy of Fallot were the most commonly found defects after discharge.
