Atrial Septal Defect (ASD) is a congenital heart condition in which there is a hole in the wall (septum) separating the two upper chambers of the heart (atria). This results in abnormal flow of oxygen-rich blood from the left atrium to the right atrium, leading to volume overload of the right heart and lungs.
ASD device closure is a safe, minimally invasive procedure that seals the defect without open-heart surgery, allowing faster recovery and excellent long-term outcomes.
Among the different types of ASD, only Ostium Secundum defects are suitable for catheter-based device closure. Other types include Ostium Primum, Sinus Venosus ASD, and Coronary Sinus ASD, which usually require surgical repair.
- Ostium Secundum ASD – most common and suitable for device closure
- Significant left-to-right shunt on echocardiography
- Right atrial or right ventricular enlargement
- Symptoms such as breathlessness, fatigue, or poor exercise tolerance
- History of stroke due to paradoxical embolism
- Early-stage pulmonary hypertension
Transcatheter ASD Device Closure: Procedure Overview
ASD device closure is a minimally invasive, scarless procedure performed in a cardiac catheterization laboratory under sterile conditions.
The procedure is done under local or general anesthesia. A catheter is introduced through a vein in the groin, the defect is assessed and sized, and an umbrella-like occluder device is deployed to seal the hole without stitches.
The procedure usually takes between 45 and 90 minutes, and most patients are discharged within 24 hours.
It avoids open-heart surgery, causes minimal pain, allows faster recovery, provides excellent long-term results, and prevents complications such as heart failure, arrhythmias, and stroke.
Yes. ASD closure is safely performed in children (usually after 3–4 years of age) and adults, helping prevent long-term complications such as pulmonary hypertension and atrial fibrillation.
Patients are prescribed aspirin with or without clopidogrel for 3–6 months, advised to avoid strenuous activity for a few weeks, avoid dental procedures for 6 months, and undergo regular echocardiographic follow-up.
