ASD (atrial septal defect) device closure

What is ASD (atrial septal defect) device closure?

ASD device closure is a minimally invasive procedure used to repair an atrial septal defect (ASD), a hole in the wall that separates the heart's upper chambers. The procedure involves inserting a small device into the ASD to close it, preventing blood from flowing between the chambers.

What causes atrial septal defects?

The exact cause of atrial septal defects isn’t fully known. However, congenital heart defects are often caused by genetic changes that happen before birth. Some genetic mutations associated with ASD affect the NKX2.5/CSX and TBX5 genes.

Some factors can raise a birthing parent’s risk of having a baby with congenital heart disease.

These factors include:

- Alcohol consumption.
- Smoking and tobacco use.
- Taking certain prescription medications.

Tests to diagnose atrial septal defects?

Electrocardiography (ECG/EKG): An ECG shows your heart’s electrical activity. It can reveal if you have an arrhythmia or other problems related to your heart’s electrical system.

Chest X-ray: This test will show if your right atrium and right ventricle are enlarged. It’ll also show if the blood vessels in your lungs are affected.

Transthoracic echocardiography (TTE): This test shows how the left-to-right shunting of blood (caused by ASD) affects your heart. It can also show details related to pulmonary hypertension.

Transesophageal echocardiography (TEE): A TEE is an ultrasound taken through your esophagus. It shows the size, shape and location of an ASD. It can also check your heart valves. TEE is often used during ASD surgery and percutaneous repair.
