A Guide to Catheter-Based Device Closure for ASD, VSD, and PDA in Children
Book Appointment
Congenital Heart Defects are the most common heart conditions that develop in children. Recent developments in Paediatric Cardiology have led to minimally invasive catheter-based treatments known as device closure, which offer a safe, effective, and faster path to recovery. ASD and VSD device closure in Kolkata is widely gaining importance as it offers a safe, effective, and faster path to recovery. Among the most commonly treated congenital heart defects using catheter-based interventions are Atrial Septal Defect (ASD), Ventricular Septal Defect (VSD), and Patent Ductus Arteriosus (PDA). Understanding these conditions is crucial for people to be aware of catheter-based congenital heart defect treatments.
At Neotia Bhagirathi Women and Child Care Centre Newtown, our Cardiac Cath Lab is dedicated to delivering safe, precise, and minimally invasive heart care for children, backed by advanced technology, experienced specialists, and excellent clinical outcomes. We offer comprehensive Hole in heart treatment through advanced Paediatric cardiac intervention techniques, enabling many congenital heart defects to be treated without the need for open-heart surgery. This blog explores congenital heart defects, explains how catheter-based device closure works, identifies which heart defects can be treated using this minimally invasive approach, discusses who may be eligible for the procedure, outlines what happens during treatment, and describes the typical recovery process.
Not all Congenital Heart Defects can be treated by device closure treatments, however it is most useful for defects where a device or balloon can safely fix the problem without open surgery.
An Atrial Septal Defect (ASD) is a hole in the wall separating the two upper chambers (atria) of the heart. This opening allows oxygen-rich blood to flow from the left atrium into the right atrium, increasing blood flow to the lungs. While small ASDs usually heal by themselves during infancy, large holes cannot be naturally mended. ASD causes shortness of breath, lethargy, heart infections and uneven weight gain during early years. ASD is one of the most common congenital heart defects that are treated by the Device Closure Procedure.
A Ventricular Septal Defect (VSD) is an opening in the wall separating the lower chambers (ventricles). It is one of the most common congenital heart defects in children. While tiny VSDs may heal on their own, moderate or large defects may lead to difficulty in breathing fully, rapid successive breathing, recurrent chest infections and various other heart problems that hinder a child’s proper growth. Device Closure Procedure in case of VSD is possible only in favourable cases. The location of VSD is much more critical than ASD, making only some of the VSDs amenable for device closure.
Before birth, a blood vessel called the ductus arteriosus connects two major arteries to bypass the lungs, which are not yet functioning. Normally, this vessel closes shortly after birth. When it remains open, the condition is known as Patent Ductus Arteriosus (PDA). Device closure procedures are commonly used for standard PDA Closure treatment without the need for an open-heart surgery or a big incision on the chest.
This is majorly a minimally invasive treatment done for treating selective congenital heart defects commonly seen in children from infancy to adolescence. Instead of an open heart surgery where the doctor performs directly on the chest, a catheter based treatment is done where a thin noodle like flexible tool called catheter is inserted and with live imaging technologies like fluoroscopy and echocardiography, a doctor observes the affected area and places the repair device in the correct position. Depending on the defect, the doctor may use:
• A closure device to seal a hole such as ASD or PDA
• A balloon to widen a narrowed valve or blood vessel
• A stent to support a narrowed artery and keep it open
Once the repair device is released, the device expands and permanently seals the opening. Over time, the body's natural tissue grows around the device, making it part of the heart structure.
When performed for the correct suitability, Catheter based treatments like Device Closure procedures have more advantages over traditional open-heart surgery.
• Minimally Invasive Procedure
• Faster Recovery Rate
• Smaller Hospital admission time
• Better success rates
• Lower risk of infection
Similar to all medical procedures, Device closure procedures have their own share of disadvantages. Not every congenital heart defects can be treated with the help of this procedure and only those that fall under the scope of a comparatively safe location are suitable for minimally invasive treatments.
• Heart infection in cases where these methods fall short
• Residual leak is also an indicator of a failed catheter treatment.
• Risk of Arrythmias
• Risk of blood clot formation
At Neotia Bhagirathi Women and Child Care Centre, Newtown, our Paediatric Cardiac Cath Lab is equipped with the latest infrastructure for minimally invasive treatments like Device Closure procedures, providing Paediatric Cardiologists with comprehensive infrastructural support. Our services in the Cardiac Cath Lab include – Diagnostic Cardiac Catheterisation, Interventional Paediatric Cardiology, including hybrid procedures.
Advances in paediatric cardiology have made ASD, VSD, and PDA device closure a safe, effective, and child-friendly alternative to open-heart surgery for many congenital heart defects. By using minimally invasive catheter-based techniques, children experience less pain, shorter hospital stays, faster recovery, and excellent long-term outcomes.
Early diagnosis and consultation with an experienced paediatric cardiologist ensure that each child receives the most appropriate treatment. With timely intervention and regular follow-up, children with congenital heart defects can enjoy healthy, active childhoods and a bright future.
Device closure is a minimally invasive catheter-based procedure that uses a specially designed device to close abnormal openings in the heart or a persistent ductus arteriosus without open-heart surgery.
For eligible children, device closure offers several advantages, including smaller incisions, less pain, shorter hospital stays, faster recovery, and minimal scarring. However, not every heart defect is suitable for this procedure.
Most children are discharged within one or two days and can usually return to normal functions within a week.
The device remains permanently inside the heart, and over time, natural heart tissue grows around it, making it part of the heart structure.
Eligibility depends on the size, location, and type of congenital heart defect, along with your child's age, symptoms, and heart function. A comprehensive evaluation by a paediatric cardiologist is essential to determine the best treatment approach.
Long-term complications are uncommon. Regular follow-up with a paediatric cardiologist helps ensure the device remains well-positioned and the heart continues to function normally.
