Atrial Septal Defect (ASD)

Overview

An atrial septal defect (ASD) is a congenital heart defect, meaning it is present at birth. It involves a hole in the wall (septum) between the heart’s two upper chambers, called the atria. This defect allows oxygen-rich blood from the left atrium to flow into the right atrium, sending it back to the lungs instead of the rest of the body. Over time, this extra blood flow can strain the heart and lungs.

Symptoms

Common symptoms of ASD in children include:

  • Shortness of breath or difficulty breathing
  • Fatigue or weakness
  • Pale or bluish skin (cyanosis)
  • Rapid heart rate or palpitations
  • Swelling in the legs, ankles, or feet
  • Poor appetite or failure to thrive

Causes

While the exact cause of ASD is unknown, it is often linked to genetic factors. Risk factors that may increase the likelihood of ASD include:

  • A family history of heart defects
  • Certain genetic syndromes, like Down syndrome
  • Exposure to specific medications or substances during pregnancy

Diagnosis

To diagnose ASD, healthcare providers will perform a thorough physical exam and take a detailed medical history. They may also use various diagnostic tests, such as:

  • Echocardiogram: uses sound waves to create images of the heart
  • Chest X-ray: helps visualize the heart and lungs
  • Cardiac catheterization: a minimally invasive test to examine the heart’s blood vessels and chambers
  • MRI or CT scan: creates detailed images of the heart

Treatment Options

The treatment for ASD depends on the size and location of the hole and the child’s overall health. Treatment options available at Gertrude’s Children’s Hospital include:

  • Surgical repair: to close the hole in the septum
  • Transcatheter closure: a less invasive procedure using a catheter to close the hole
  • Medications: to manage symptoms and prevent complications
  • Heart transplantation: in severe cases where other treatments are ineffective

Atrial Septal Defect (ASD) in Children

With timely treatment, most children with ASD can lead active, healthy lives. However, untreated ASD may lead to complications like heart failure or arrhythmias later in life.

ASD is diagnosed through a combination of physical exams, echocardiograms, chest X-rays, and other imaging tests.

Treatment may include surgical repair, transcatheter closure, and medications to manage symptoms and prevent complications.
