Many babies born with atrial septal defects don't have associated signs or symptoms. In adults, signs or symptoms usually begin by age 30, but in some cases signs and symptoms may not occur until decades later.

Atrial septal defect signs and symptoms may include:

  • Shortness of breath, especially when exercising
  • Fatigue
  • Swelling of legs, feet or abdomen
  • Heart palpitations or skipped beats
  • Frequent lung infections
  • Stroke
  • Heart murmur, a whooshing sound that can be heard through a stethoscope

When to see a doctor

Contact your doctor if you or your child has any of these signs or symptoms:

  • Shortness of breath
  • Tiring easily, especially after activity
  • Swelling of legs, feet or abdomen
  • Heart palpitations or skipped beats

These could be signs or symptoms of heart failure or another complication of congenital heart disease.
