Atrial Septal Defects

Symptoms & Signs

What are the signs and symptoms of the condition?

Symptoms of an ASD depend on how large the defect is and where it is located. People with small defects may not have any symptoms. Symptoms can occur during infancy and childhood if there is a large defect. Many times, symptoms do not appear until adolescence or adulthood. Someone with an ASD may have the following symptoms:

delays in a child's development, including thinking and motor functions

difficulty breathing and shortness of breath, often made worse by activity

fatigue

failure to thrive, which is a slow growth rate in infants

heart murmurs that a healthcare provider can hear with a stethoscope
