Before a baby is born, a small blood vessel called the 'ductus arteriosus' plays an important role in foetal circulation by allowing blood to bypass the lungs. After birth, this vessel is expected to close naturally within the first few days of life. However, when it remains open, the condition is known as Patent Ductus Arteriosus (PDA).
A small PDA may not cause any problems and sometimes closes on its own. However, a larger opening can force the heart and lungs to work harder, increasing the risk of complications if left untreated. Fortunately, modern PDA surgery and minimally invasive closure procedures offer excellent outcomes for both children and adults.
In this guide, we'll explain what patent ductus arteriosus is, when treatment is needed, the PDA closure procedure, recovery, and the PDA surgery cost in India.
What is Patent Ductus Arteriosus (PDA)?
Patent Ductus Arteriosus (PDA) is a congenital heart condition in which the ductus arteriosus, a temporary blood vessel present before birth, fails to close after delivery.
Normally, this vessel is no longer needed once a baby starts breathing on its own. If it remains open, extra oxygen-rich blood flows from the aorta into the pulmonary artery, causing the heart and lungs to work harder than normal.
The impact depends largely on the size of the opening. While some children remain symptom-free, others may require treatment to prevent long-term heart and lung complications.
Who is at higher risk of PDA?
PDA can occur in any newborn, but it is more commonly seen in the following:
Premature babies
Low birth weight infants
Girls, who are affected more often than boys
Children born with other congenital heart defects
A premature baby heart defect like PDA is often identified soon after birth because premature infants have a higher chance of the ductus arteriosus remaining open.
Symptoms of Patent Ductus Arteriosus (PDA)
A small PDA may not produce any noticeable symptoms and is sometimes detected during a routine examination when a doctor hears a heart murmur.
A moderate or large PDA may cause the following:
Fast or difficult breathing
Poor feeding in infants
Slow weight gain
Excessive sweating during feeding or crying
Easy tiredness
Frequent respiratory infections
The severity of symptoms usually depends on the size of the PDA and how much extra blood is flowing to the lungs.
How is PDA diagnosed?
If a doctor suspects PDA, several tests may be recommended to confirm the diagnosis and assess its severity.
Common investigations include:
Echocardiogram (the primary test for diagnosing PDA)
Chest X-ray
Oxygen saturation monitoring
Cardiac MRI or CT scan in selected cases
Cardiac catheterization when additional evaluation is required
These tests help determine the size of the opening and guide the most appropriate treatment plan.
Can PDA close without surgery?
Yes, in some cases only. Small PDAs may close naturally during infancy and only require regular monitoring by a paediatric cardiologist.
In premature newborns, doctors may also prescribe medications such as indomethacin for PDA or ibuprofen to encourage the ductus arteriosus to close. These medicines are generally effective only during the early newborn period.
If the PDA remains open, causes symptoms, or affects heart function, a closure procedure may be recommended.
When is PDA treatment recommended?
Treatment depends on the size of the PDA, the patient's age, symptoms, and its effect on the heart and lungs.
Doctors may recommend closure if:
The PDA is moderate or large.
The baby has feeding difficulties or poor weight gain.
Breathing becomes difficult.
There is increased blood flow to the lungs.
The heart is becoming enlarged.
There is a risk of long-term lung damage or heart failure.
Early treatment helps prevent complications and supports healthy growth and development.
PDA closure procedure
There are two primary treatment options for closing a PDA.
PDA device closure in children
Today, PDA device closure in children is the preferred treatment for many older infants and children.
During this minimally invasive procedure, a cardiologist inserts a thin catheter through a blood vessel in the groin and guides it to the heart. A small closure device is then placed inside the PDA to block the abnormal blood flow.
The procedure usually offers:
No large chest incision
Faster recovery
Short hospital stay
High success rates
Most children return home the same day or after a brief observation period.
PDA surgery in newborns
Some babies, especially premature infants or those with a very large PDA, may require open-heart surgery instead of catheter-based treatment.
During PDA surgery in newborns, the surgeon reaches the ductus through a small incision between the ribs and closes it using stitches or a small surgical clip. Unlike many other congenital heart surgeries, the heart itself usually does not need to be opened.
The choice between surgery and device closure depends on the baby's age, weight, anatomy, and overall health.
Recovery after PDA surgery
Recovery depends on the type of treatment performed.
After device closure, most children recover quickly and resume normal activities within a few days.
After surgery:
Hospital stay is generally a few days.
Pain is usually mild and improves gradually.
Follow-up visits help monitor healing.
Some patients may receive temporary antibiotics to reduce the risk of infection.
The long-term outlook after successful PDA treatment is excellent, with most children living healthy, active lives.
Difference between PDA, VSD and ASD
Although all three are congenital heart defects, they affect different parts of the heart.
PDA | ||
Open blood vessel between the aorta and pulmonary artery | Hole between the lower heart chambers | Hole between the upper heart chambers |
Common in premature infants | Affects the ventricular septum | Affects the atrial septum |
Often treated with device closure | May require surgery or device closure | Often suitable for catheter closure |
A paediatric cardiologist determines the appropriate treatment based on the specific heart defect.
Success rate of PDA surgery
The PDA surgery success rate is excellent. Both catheter-based closure and surgery have high success rates when performed by experienced cardiac teams.
Most patients recover completely and require only periodic follow-up to ensure the heart continues to function normally.
PDA surgery cost in India
The PDA surgery cost in India varies depending on factors such as:
Type of treatment (device closure or surgery)
Hospital and city
Patient's age and overall condition
ICU stay and hospital charges
Diagnostic tests and follow-up care
A detailed evaluation by a pediatric or adult cardiac specialist is the best way to understand the expected treatment plan and overall cost.

Conclusion
A diagnosis of Patent Ductus Arteriosus can be concerning for families, but timely diagnosis and appropriate treatment offer excellent outcomes. While some small PDAs close naturally or respond to medication in premature babies, larger defects often require PDA device closure or surgery to prevent future complications.
The good news is that advances in paediatric cardiac care have made PDA surgery highly successful, allowing most children to grow up healthy and active. Consulting an experienced cardiologist at the right time can make a significant difference in long-term heart health.

FAQs
Q: What is Patent Ductus Arteriosus (PDA)?
Patent Ductus Arteriosus (PDA) is a congenital heart condition in which the ductus arteriosus remains open after birth, allowing abnormal blood flow between the aorta and the pulmonary artery.
Q: Can PDA Close Without Surgery?
Yes. Small PDAs may close naturally, and in premature newborns, medications such as indomethacin or ibuprofen may help the ductus close during the early newborn period.
Q: What is the difference between PDA surgery and device closure?
Device closure uses a catheter inserted through a blood vessel to place a closure device inside the PDA, while surgery closes the vessel through a small incision in the chest. The choice depends on the patient's age, anatomy, and overall condition.
Q: Is PDA Surgery Safe for Newborns?
Yes. When recommended by a paediatric cardiac surgeon, PDA surgery is considered a safe and effective treatment, particularly for premature babies or those with a large PDA.
Q: What happens if PDA is left untreated?
A large untreated PDA can increase the workload on the heart and lungs, leading to breathing difficulties, poor growth, pulmonary hypertension, heart failure, and other complications over time.
Q: What is the cost of PDA surgery in India?
The cost varies based on the type of procedure, hospital, city, patient's condition, and post-operative care. A consultation with a cardiac specialist can provide a personalized estimate.
