Atrial Septal Defect (ASD) Repair

Fixing a Hole in the Heart Without Surgery

An atrial septal defect (ASD) is an opening or hole in the atrial septum, a wall of tissue that separates the two upper chambers of the heart.

Although ASDs occur at birth, they commonly remain undetected until adulthood. A small opening may never cause a problem and may be found during an unrelated heart procedure or examination. Larger holes can lead to damage to the heart and lungs. An untreated ASD may lead to symptoms such as shortness of breath, fatigue, decreased ability to exercise, irregular heartbeats, strokes, or fainting.

The most common type of ASD can typically be closed using a nonsurgical procedure. A specially trained physician inserts a tube called a catheter into a vein near the groin. A specially designed ASD closure device is advanced into the heart through the tube and placed in the defect to seal it closed. Tissue gradually grows over the device to further seal the ASD.

Catheter Repair of ASD

If left untreated, ASDs in adults can lead to increased risk of having a stroke, heart failure, or pulmonary hypertension (a disease that causes increased pressure and irreparable damage to the heart and lungs). 

In the past, closing an ASD required open-heart surgery. Now, catheter repair is the most frequent treatment for the most common type of ASD. This offers patients less pain and a shorter recovery. More rare or complex types of ASDs may still require surgery.

After taking a thorough history of your symptoms and conducting an evaluation with diagnostic imaging tests, your doctor will determine if an ASD repair is necessary and whether a repair via catheter or surgery is right for you.
