Atrial Septal Defect
Diagnosis

Most atrial septal defects (ASD) are discovered during childhood when a murmur, an extra heart sound, is heard during a physical examination.

To help diagnosis ASD in adulthood, your doctor also may suggest the following tests:

  • Electrocardiogram (EKG or ECG), which records the heart's electrical activity
  • Chest X-ray to see the heart's size
  • Echocardiogram, which is an ultrasound examination of the heart

In addition, your doctor may use a cardiac catheterization procedure to inject a dye into the heart and to see on a moving picture X-ray how the heart and aorta are functioning.

Coronary angiography may be recommended for patients over age 40 to detect coronary artery disease.
