Atrial Septal Defect (ASD)

What is Atrial Septal Defect?

Atrial Septal Defect (ASD) is a congenital heart condition characterized by a hole in the wall, known as the septum, that separates the heart’s upper chambers (atria). This allows oxygen-rich and oxygen-poor blood to mix, leading to lower oxygen levels in the blood and potential complications.


Symptoms can vary widely and may include:

  • Shortness of breath, especially during exercise
  • Fatigue
  • Rapid heartbeat or palpitations
  • Frequent respiratory infections in children
  • Swelling of the legs, feet, or abdomen

Treatment Options

Treatment for ASD may involve:

  • Observation and regular check-ups for smaller defects
  • Medications to manage symptoms
  • Catheter-based procedures to close the hole
  • Open-heart surgery for larger or more complicated defects

If you suspect you or a loved one may have an Atrial Septal Defect, early diagnosis and treatment are critical. Schedule your appointment with our congenital heart specialists today for a thorough evaluation and customized treatment plan.
