What is PDA Device Closure?
Patent Ductus Arteriosus (PDA) is a congenital heart defect in which the ductus arteriosus, a normal fetal blood vessel connecting the pulmonary artery to the aorta, fails to close after birth. When the PDA remains open, oxygen-rich blood flows back into the lungs instead of circulating normally through the body. Over time, this can enlarge the heart, increase pressure in the lungs, and lead to heart failure if left untreated.
PDA device closure seals the abnormal opening using a specially designed closure device delivered through a catheter inserted into a blood vessel, eliminating the abnormal blood flow.
India has become one of the leading destinations for PDA device closure because of its experienced pediatric cardiologists, advanced cardiac catheterization laboratories (Cath Labs), internationally accredited hospitals, excellent success rates, and affordable treatment costs.
Who Needs PDA Device Closure?
Your orthopedic surgeon may recommend this procedure if you have:
- Moderate Patent Ductus Arteriosus
- Large Patent Ductus Arteriosus
- Left heart enlargement due to PDA
- Pulmonary over-circulation
- Congestive heart failure caused by PDA
- Failure to thrive in infants
- Frequent respiratory infections
- Shortness of breath
- Exercise intolerance
- Significant left-to-right shunt
- Device closure is generally preferred for suitable patients weighing more than 6 kg, while surgery may be recommended for certain infants or patients with unsuitable PDA anatomy.
Common Causes
Symptoms
- Heart murmur
- Rapid breathing
- Shortness of breath
- Poor feeding in infants
- Poor weight gain
- Frequent chest infections
- Excessive sweating during feeding
- Fatigue
- Delayed growth
- Exercise intolerance
- Small PDAs may produce no symptoms and are detected during routine examination.
Diagnosis
- 2D Echocardiography
- Color Doppler Echocardiography
- ECG
- Chest X-ray
- Cardiac CT (selected patients)
- Cardiac Catheterization (if required)
- Complete Blood Count (CBC)
- Kidney Function Tests
- Liver Function Tests
- Coagulation Profile
- Blood Grouping
- Oxygen Saturation Assessment
- Anesthesia evaluation
Types of PDA Device Closure
PDA Device Closure
The preferred treatment for most children and adults with suitable PDA anatomy. Benefits include no chest incision, no open-heart surgery, faster recovery, short hospital stay, and excellent cosmetic results.
Coil Closure
Suitable for selected small PDAs, using detachable coils delivered through a catheter.
Surgical PDA Ligation
Recommended for very small infants, patients weighing less than 6 kg (in many cases), large or unusual PDA anatomy unsuitable for device closure, and failed device closure.
Benefits
- Minimally invasive procedure
- No open-heart surgery
- No large chest scar
- Short hospital stay
- Faster recovery
- Prevents heart enlargement
- Reduces pulmonary hypertension risk
- Prevents recurrent respiratory infections
- Improves growth and exercise tolerance
- Excellent long-term outcomes
The Procedure
- Pre-procedure evaluation
- Administration of local anesthesia with sedation or general anesthesia (depending on age)
- Catheter insertion through a vein or artery in the groin
- Advancement of the catheter to the PDA
- Angiographic assessment of the duct
- Placement of the PDA occlusion device
- Confirmation of complete closure using echocardiography and angiography
- Release of the device
- Removal of the catheter
- Recovery and observation
Duration: The surgery usually takes 30–90 minutes, depending on the patient's anatomy and procedural complexity..
Recovery Timeline
Success Rate
PDA device closure is one of the most successful congenital cardiac interventions, with leading pediatric cardiac centers in India reporting success rates exceeding 98–99% for appropriately selected patients; overall success depends on factors such as PDA size, PDA anatomy, the patient's age, pulmonary artery pressure, device selection, the cardiologist's expertise, and hospital infrastructure.
Risks
Although pda device closure is generally safe, possible risks include:
Cost of PDA Device Closure in India
The final cost depends on: Hospital category, Pediatric cardiologist's expertise, PDA size and anatomy, Closure device type, ICU stay (if required), Room category, Diagnostic investigations, Patient's age, Associated congenital heart defects.

Frequently Asked Questions
PDA device closure is a minimally invasive catheter-based procedure that closes a Patent Ductus Arteriosus using a specially designed occlusion device without open-heart surgery.
For patients with suitable anatomy, device closure is generally the preferred treatment because it is less invasive, provides faster recovery, and avoids a chest incision.
Most PDA device closure procedures take 30–90 minutes.
No. The procedure is performed under local anesthesia with sedation or general anesthesia, so patients do not feel pain during the intervention.
Most patients are discharged within 24 hours after the procedure.
International patients are generally advised to remain in India for 5–7 days for follow-up evaluation before returning home.
Yes. Adults with a suitable PDA and no contraindications can also undergo successful catheter-based PDA device closure after comprehensive evaluation.
Most patients require regular follow-up during the first year after closure. If there is no residual defect or pulmonary hypertension, long-term follow-up is often minimal.
Yes. Most children and adults recover completely and lead normal, healthy lives after successful PDA closure.
Medicare Spots assists international patients with expert pediatric cardiology opinions, hospital and specialist selection, treatment planning, medical visa support, travel arrangements, accommodation, dedicated patient coordination, and post-treatment follow-up to ensure a smooth treatment journey in India.
