I want to own my own daycare for kids with special needs.

Atrial Septal Defect: Signs and Symptoms


What are the signs and symptoms of atrial septal defect (ASD)?

Your child's symptoms will depend on the size and location of the septum hole. Most children with atrial septal defects (ASD) have no outward symptoms, and they grow and gain weight normally.

Patients with larger, more severe ASDs may experience poor growth and weight gain, decreased appetite, fatigue and shortness of breath. Recurring lung problems and pneumonia are also potential signs of the condition. Some children faint, particularly after exercise or activity.
