In newborns with Down syndrome, which test is routinely used to assess congenital heart disease?

• A. EKG
• B. Chest X-ray
• C. MRI head
• D. Echocardiography

Answer: (D)

Infants with Down syndrome have a high risk of congenital heart defects, so we screen early to catch problems that can affect prognosis and treatment. Echocardiography uses ultrasound to visualize the heart’s anatomy and function in real time. It can identify septal defects like atrioventricular canal defects, valve abnormalities, and outflow tract issues, determine severity, and guide management, all without radiation or invasive procedures. This makes it the test of choice for routinely assessing congenital heart disease in newborns with Down syndrome. EKG shows electrical activity and can detect rhythm problems but doesn’t reveal structural heart defects. Chest X-ray can suggest cardiomegaly or edema but lacks the detail of anatomy. MRI of the head isn’t used for evaluating heart disease.
