PDA Device Closure in India
PDA device closure in India from $3,500. Catheter-based closure — no surgery needed. 99% success rate. Apollo, Medanta, Fortis. Next-day discharge.
Estimated cost: $3,500 – $6,500 · Average stay: 1–2 days
The ductus arteriosus is a foetal blood vessel connecting the pulmonary artery to the aorta, allowing blood to bypass the foetal lungs. It normally closes within hours to days after birth. When it fails to close (patent ductus arteriosus, PDA), blood flows from the high-pressure aorta back into the pulmonary artery, causing excess pulmonary blood flow, respiratory distress, heart failure, and — in large PDAs — pulmonary hypertension.
Device closure is now the standard treatment for PDA in all but premature neonates (who are treated with indomethacin or surgical ligation). The Amplatzer Duct Occluder, Lifetech ADO, and KONAR-MF device are delivered through a catheter from the femoral vein, deployed across the PDA, and permanently occlude the vessel. The procedure takes 30–45 minutes; the child is discharged the next day.
India performs thousands of PDA device closures annually. The procedure costs $3,500–$6,500 in India compared to $15,000–$30,000 in the United States.
Device vs. Surgical PDA Closure
Device closure is preferred for all PDAs in children weighing >5 kg with appropriate anatomy. Devices suitable for all sizes of PDA are now available — from the Piccolo (for very small PDAs) to large ADO-II or plug devices for tubular or large PDAs. Surgical ligation is reserved for premature neonates (<2 kg) in whom catheter access is too small, or rare anatomical situations unsuitable for device closure.
Who Needs PDA Closure?
PDA closure is recommended for all symptomatic PDAs regardless of size, and for asymptomatic PDAs with cardiomegaly or increased pulmonary vascular markings on chest X-ray. Silent PDAs (detected only on echo with no haemodynamic significance) are controversial; most guidelines recommend closure to prevent the small risk of endocarditis.
Contraindications: severe irreversible pulmonary hypertension (Eisenmenger syndrome) where the PDA provides essential right-to-left shunt; premature neonates below device access threshold weight.
How is PDA Device Closure Performed?
Under sedation or general anaesthesia, the femoral vein is accessed. A catheter is advanced to the right heart, then through the PDA into the aorta. An angiogram maps the PDA anatomy. The Amplatzer Duct Occluder (or equivalent device) is advanced through the catheter and deployed in the aortic ampulla of the PDA, then the pulmonary end is opened within the PDA, occluding it. Position is confirmed by angiography and transoesophageal echocardiography. If no residual shunt is confirmed, the device is released. The catheter is removed; the child observed for 4–6 hours and discharged the next morning.
Procedure Steps
- Echocardiogram: confirms PDA anatomy, measures minimum diameter, aortic ampulla, and length.
- Anaesthesia: sedation for older children; general anaesthesia for young infants.
- Femoral vein access: 4–7 French sheath.
- Right heart catheterisation: pulmonary artery and aortic pressures measured.
- Catheter advanced through PDA; aortogram to define PDA shape.
- Device selection: ADO-II size = PDA minimum diameter + 2 mm.
- Device delivery: aortic retention disc opened first; then PDA body and pulmonary disc.
- Position check: echocardiography and angiography confirm device position.
- Device release; sheath removal; groin compressed 5 minutes.
- Next-day discharge with aspirin for 6 months.

Recovery & Follow-up
PDA device closure recovery is very fast. The child is observed for 4–6 hours after the procedure and discharged the next morning. Normal activity can resume within 2–3 days. Aspirin is prescribed for 6 months. A follow-up echocardiogram at 6 months confirms device position and confirms closure.
Recovery Tips
- Aspirin 3–5 mg/kg/day for 6 months to prevent thrombus during device endothelialisation.
- Avoid contact sports for 6 weeks after device closure.
- Antibiotic prophylaxis for dental procedures for 6 months after implantation.
- Follow-up echocardiogram at 6 months and 1 year.
- Report any fever, unexplained illness (endocarditis risk, very low but monitor).
Risks & Complications
PDA device closure risks: device embolisation (0.3–1%), residual shunt (1–3%), haemolysis in rare cases of high-velocity residual shunt, femoral vessel injury, left pulmonary artery stenosis (device prolapse into pulmonary artery, rare), and aortic arch obstruction (device prolapse, rare). Technical failure requiring surgical retrieval is very rare (<0.5%).
Why GAF Healthcare
Gaf Healthcare arranges PDA device closure at India's busiest paediatric catheterisation laboratories. Our cardiologist partners have performed thousands of PDA closures using all available device systems and can advise on the best device for each specific PDA anatomy. We coordinate same-week procedures for families travelling specifically for this treatment.
Frequently Asked Questions
Can all PDAs be closed by catheter?
Approximately 95% of PDAs in children >5 kg are suitable for device closure. The remaining 5% — very large PDAs with short length, or PDAs in very small premature infants — require surgical ligation.
At what age can PDA device closure be done?
Device closure is routinely performed from 6 months of age (or ~5 kg). For symptomatic infants below this threshold, surgical ligation or indomethacin treatment is used first.
How do I know if my child has a PDA?
PDA is usually detected by a cardiologist hearing a continuous 'machinery' murmur at the left upper sternal border on auscultation, or incidentally on echocardiography. Echocardiography confirms the diagnosis, anatomy, and haemodynamic significance.
Will the device stay in my child's heart forever?
Yes. The device is permanent and is covered by the child's own heart tissue within 3–6 months. It is made of nitinol, a biocompatible alloy with lifelong durability.
Can a PDA close on its own?
Small PDAs in full-term infants sometimes close spontaneously in the first 3–6 months of life. Persistent PDAs beyond 1 year are unlikely to close spontaneously and should be closed to prevent long-term complications.
