PDA Closure
VSD PDA Closure Time: Procedure, Devices & Recovery
- Patent ductus arteriosus (PDA) is a congenital heart condition where a blood vessel that should close after birth remains open. This vessel, called the ductus arteriosus, connects the aorta and pulmonary artery during fetal development.
- Normally, the ductus arteriosus closes naturally within the first few days of life. However, in some infants—especially premature babies—the vessel remains open. When this happens, extra blood flows to the lungs instead of the body, causing the heart and lungs to work harder.
- Modern treatments allow doctors to close this vessel safely. One of the most common questions parents ask is about PDA closure time and how long the procedure takes.
- Leading pediatric cardiac centers such as Amrita Hospital Faridabad provide advanced PDA closure procedures with modern minimally invasive techniques.
What Is Patent Ductus Arteriosus (PDA)?
The ductus arteriosus is a normal fetal blood vessel that allows blood to bypass the lungs before birth.
After birth:
- The lungs begin functioning.
- The ductus arteriosus should close within 24–72 hours.
When it remains open, the condition is called Patent Ductus Arteriosus (PDA).
This can cause:
- Increased blood flow to the lungs
- Breathing difficulties
- Poor weight gain
- Heart enlargement
- Heart failure in severe cases
PDA occurs in approximately 1 in 2,000 births and is more common in premature infants.
Why PDA Closure Is Needed
When the ductus arteriosus remains open, oxygen-rich blood from the aorta flows back into the pulmonary artery.
How PDA Affects Blood Circulation
This abnormal circulation leads to:
- Excess blood flow to the lungs
- Increased pressure in pulmonary arteries
- Overworking of the heart
If untreated, PDA may lead to long-term complications such as pulmonary hypertension or heart failure.
Closing the PDA restores normal blood circulation.
PDA Closure Indications
Doctors recommend PDA closure when the condition causes symptoms or significant blood flow abnormalities.
Common PDA closure indications include:
- Breathing problems
- Poor feeding or growth
- Enlarged heart
- Heart murmur
- Increased pulmonary blood flow
- Risk of endocarditis
Treatment decisions depend on the size of the PDA and the baby’s overall health.
Types of PDA Closure Treatments
Treatment options vary depending on the infant’s age, weight, and severity of the condition.
Medication Treatment
- In premature infants, medications such as indomethacin or ibuprofen may help close the ductus arteriosus.
Transcatheter PDA Closure
- This is the most common modern treatment.
- Doctors insert a thin catheter through a blood vessel in the groin and guide it to the heart. A small closure device is then placed in the ductus arteriosus.
- This method is minimally invasive and avoids open-heart surgery.
Surgical PDA Ligation
- In rare cases, especially when catheter closure is not possible, surgeons perform PDA ligation surgery.
- This involves tying or clipping the ductus arteriosus through a small chest incision.
Types of PDA Closure Devices
Several specialized devices are used to close the ductus arteriosus.
Common types of PDA closure devices include:
- Amplatzer PDA occluder
- Amplatzer Piccolo device
- Coil closure devices
- Nit-Occlud PDA device
Coil Closure of PDA
In smaller PDAs, doctors may use tiny coils that block blood flow and encourage natural tissue growth to seal the vessel.
These devices remain permanently in the heart but become covered by tissue over time.
PDA Closure Procedure Step-by-Step
A transcatheter PDA closure procedure generally follows these steps:
- The patient receives sedation or general anesthesia.
- A catheter is inserted through a blood vessel in the groin.
- Using X-ray imaging, the catheter is guided to the heart.
- The PDA closure device is deployed into the ductus arteriosus.
- The device blocks abnormal blood flow.
- The catheter is removed.
The procedure is performed in a specialized cardiac catheterization laboratory.
How Long Does PDA Closure Take?
One of the most common questions parents ask is about PDA closure time.
Typically:
- The transcatheter PDA closure procedure takes about 30–60 minutes.
- Preparation and recovery monitoring may take several hours.
- Most patients remain in the hospital 24–48 hours for observation.
Compared with open surgery, catheter-based closure has a much shorter procedure time and faster recovery.
PDA Closure Time in Premature Infants
Premature infants often require special care during treatment.
The PDA closure time in premature infants may vary depending on:
- The baby’s weight
- The size of the PDA
- Overall health condition
- NICU support requirements
Many premature infants undergo device closure within 30–45 minutes, followed by monitoring in the neonatal intensive care unit.
Advances in medical technology now allow closure in babies weighing as little as 700 grams.
Recovery After PDA Closure
Recovery after transcatheter PDA closure is usually quick.
Most infants experience:
- Improved breathing
- Better feeding
- Increased oxygen levels
- Reduced strain on the heart
Typical recovery includes:
- Monitoring in the hospital for 24–48 hours
- Follow-up echocardiograms
- Routine pediatric cardiology checkups
The closure device becomes part of the heart tissue over time.
Benefits and Risks of PDA Closure
Benefits
- Restores normal blood circulation
- Improves oxygen levels
- Prevents heart failure
- Reduces risk of lung complications
- Allows normal growth and development
Possible Risks
Although rare, potential complications include:
- Device movement
- Bleeding
- Infection
- Irregular heart rhythm
- Residual shunt
In experienced cardiac centers, the success rate of PDA closure is very high.

FAQ
How long does PDA closure take?
The PDA closure procedure typically takes 30 to 60 minutes, although preparation and recovery monitoring may extend the hospital stay.
What are the types of PDA closure devices?
Common devices include the Amplatzer PDA occluder, Amplatzer Piccolo device, and coil closure devices.
Is PDA closure safe for premature babies?
Yes. Modern catheter-based techniques allow PDA closure even in very small premature infants.
What is coil closure of PDA?
Coil closure is a catheter-based procedure where small metal coils are placed in the ductus arteriosus to block blood flow and close the vessel.
What is recovery time after PDA closure?
Most babies recover quickly and can go home within 1–2 days after the procedure.
