ASD / VSD & PDA Device Closure
- Home \ ASD / VSD & PDA Device Closure
What It Is and Why It’s Done
Certain heart defects are present from birth, such as Atrial Septal Defect (ASD), Ventricular Septal Defect (VSD), and Patent Ductus Arteriosus (PDA). These are small openings or abnormal connections in the heart that affect how blood flows. If left untreated, they can lead to complications like heart enlargement, breathlessness, or high pressure in the lungs. Traditionally, these defects required open-heart surgery. Today, most cases can be treated through a non-surgical procedure called device closure. Using a catheter inserted through a blood vessel, a small device is placed to seal the opening — without the need for stitches or a large scar.
What Patients Gain from Device Closure
These advanced treatments give hope and options to patients who otherwise may not benefit from standard procedures.
Minimally Invasive, No Open Surgery
The procedure avoids open-heart surgery, meaning no chest incision, fewer risks, and faster recovery.
Quick Return to Normal Life
Most patients can return home within 24–48 hours and resume daily activities much sooner compared to traditional surgery.
Effective and Long-Term Results
Device closure provides a permanent solution for many congenital defects, restoring normal blood flow and preventing long-term complications like heart failure or lung damage.
Key Highlights of Device Closure
- Non-surgical treatment for ASD, VSD, and PDA
- Small catheter-based procedure with no major scars
- Short hospital stay and faster recovery
- Safe and effective for both children and adults
- Proven long-term outcomes with reduced risk of complications
Frequently Asked Questions
Find clear answers to common questions about angiogram, preparation, safety, recovery, and more to help you feel confident and informed
Is device closure safe for children?
Yes. Device closure is widely performed in both children and adults and is considered very safe when done by experienced cardiologists.
How long does the procedure take?
It usually takes 1–2 hours, followed by a short observation period.
Will the device stay permanently?
Yes. The device stays in place and the heart tissue gradually grows around it, making it a permanent closure.
How soon can normal activities be resumed?
Most patients can return to school or work within a few days. Strenuous activity may need to wait a few weeks.
Are there any risks?
Complications are rare. Mild risks include bleeding at the catheter site or device movement, but these are very uncommon with modern techniques.
