An atrial septal defect (ASD) is a congenital heart defect that occurs when there is a hole in the wall between the upper chambers of the heart, known as the atria. This hole allows blood to flow between the two atria, which can lead to an overload of blood in the right atrium and ventricle.
Symptoms
The exact cause of ASD is not always clear, but it often occurs due to a mix of genetic and environmental factors. In some cases, ASD can run in families, suggesting that genes may play a role. Certain factors during pregnancy, like exposure to alcohol, drugs, or infections, might also increase the risk of ASD. However, in many instances, the cause is not identified, and it happens without any known reason.
Causes
- Shortness of breath
- Fatigue
- Swelling in the legs, ankles, or feet
- Palpitations or irregular heartbeat
- Chest pain or discomfort
Interventions
Surgical interventions for ASDs are typically performed to close the hole in the atrial septum and prevent further complications. The type of surgery performed depends on the size and location of the ASD, as well as the individual’s overall health
Types of Surgical Interventions
- Open-heart surgery: This is a traditional surgical approach that involves making an incision in the chest and using a heart-lung machine to bypass the heart and lungs during the procedure.
- Minimally invasive surgery: This is a less invasive surgical approach that involves making smaller incisions in the chest and using specialized instruments to close the ASD.
- Catheter-based procedures: These are minimally invasive procedures that involve using a catheter to close the ASD. The catheter is inserted through a vein in the leg and guided to the heart, where a device is deployed to close the ASD.
- Transcatheter closure: This is a minimally invasive procedure that involves using a catheter to deploy a device that closes the ASD.
