Between 40 and 60% of babies with Down syndrome have congenital heart defects, the commonest being atrioventricular septal defect.
Pulmonary arterial hypertension, is also common and can affect those with or without congenital heart disease.
Screening in the newborn period is essential as signs and symptoms of these problems may not be present and prompt diagnostic assessment and treatment is important to reduce the long term impact.
Even with early treatment, many children with Down syndrome will have ongoing complications and pulmonary arterial hypertension. Close surveillance and active management throughout childhood and into adulthood is needed in order to optimise quality of life long term.
