  • Congenital HD lesions, common in Trisomy 21 (T21), may be difficult to appreciate on fetal imaging. Therefore, a postnatal echocardiogram is important to rule out abnormalities.
  • Despite a higher likelihood of obesity, adults with T21 have lower risks for common CV risk factors and adult-acquired cardiovascular (CV) diseases such as diabetes, hypertension, hypercholesterolemia, and coronary artery disease.
  • The establishment of a medical home for individuals with congenital HD and T21 will promote continuity of care, family-centered care, health promotion, and advocacy.
