PDA Device Closure
PDA Device Closure is a minimally invasive procedure that permanently seals a Patent Ductus Arteriosus using a small occluder device delivered by catheter — restoring normal heart circulation and protecting the heart and lungs from long-term damage without the need for open-heart surgery.
Overview
PDA Device Closure treats a Patent Ductus Arteriosus — a small blood vessel that should close naturally after birth but remains open — using a carefully designed occluder device guided through a thin catheter and deployed to permanently seal the abnormal connection. This catheter-based approach is now the preferred treatment for most patients with PDA, delivering excellent results with minimal recovery time compared to surgical ligation. Once deployed, the device becomes incorporated into heart tissue within weeks, restoring completely normal cardiac circulation.
Types of PDA Device Closure
PDA closure can be performed using different device types depending on the size, shape, and anatomy of the ductus arteriosus. Your cardiologist will select the most appropriate device after detailed echocardiographic assessment.
- Amplatzer Duct Occluder (mushroom-shaped device for moderate to large PDAs)
- Coil Embolisation (small metal coil for tiny PDAs)
- Vascular Plug Device Closure (for tubular or window-type PDAs)
- Muscular VSD Occluder (for large window-type ductus)
- Surgical PDA Ligation (reserved for cases unsuitable for catheter closure)
Risk Factors of Patent Ductus Arteriosus
While PDA is a congenital condition, certain factors increase the likelihood of its occurrence or delay natural closure. Understanding these helps families seek timely specialist evaluation.
- Premature birth — significantly more common in babies born before 37 weeks
- Maternal rubella infection during the first trimester of pregnancy
- Female sex — PDA occurs approximately twice as often in girls
- Living at high altitude increases incidence of persistent PDA
- Family history of congenital heart defects
- Genetic syndromes such as Down syndrome associated with structural heart anomalies
PDA Symptoms
Symptoms of PDA vary depending on the size of the opening and the patient's age. Small PDAs may cause no symptoms, while large ones significantly affect heart and lung function.
- A continuous machinery-like heart murmur heard by a doctor
- Frequent chest infections or recurrent pneumonia in infants and children
- Poor feeding and failure to thrive in infants with significant PDAs
- Rapid breathing or breathlessness during feeding or activity
- Easy fatigue or reduced exercise tolerance in older children and adults
- Palpitations or awareness of irregular heartbeat
- Enlarged heart or pulmonary hypertension detected on investigation
- Recurrent respiratory illnesses disproportionate to the patient's age

Restores completely normal cardiac circulation and allows normal growth and development
Quick recovery with most children returning to normal activities within 3 to 5 days
Clinical Features
The technology, techniques and clinical approach behind our pda device closure.
Catheter-based closure avoids open-heart surgery and its associated risks and recovery
General anaesthesia ensures complete comfort and stillness for precise device deployment
Continuous echocardiographic and fluoroscopic guidance throughout the procedure
Multiple device sizes available to achieve a perfect anatomical fit for every PDA
Immediate echocardiographic confirmation of complete closure before discharge
Preparation Instructions
- Complete a detailed echocardiogram and chest X-ray to plan device sizing
- Ensure blood tests including CBC, coagulation, and kidney function are completed
- Fast for 4 to 6 hours before the procedure
- Inform your cardiologist of all medications
- Arrange for a parent or guardian to accompany paediatric patients at all times
- Report any history of allergy to contrast dye, metal implants, or anaesthetic agents
- Arrange transportation home as the patient will not be fit to travel independently post-procedure
- Bring all current medications and allergy records to the hospital on admission day
The Procedure
Step-by-step guide to what you can expect during your pda device closure procedure.
Paediatric Cardiology Assessment
Your paediatric cardiologist performs a detailed echocardiogram and clinical evaluation to precisely measure the PDA size, assess the direction and volume of abnormal blood flow, and confirm that catheter-based device closure is the most appropriate and safe treatment for your child's specific defect.
Safe Preparation for the Procedure
Our dedicated paediatric team prepares your child carefully — confirming all pre-operative investigations, fasting status, consent, and anaesthetic plan. We understand how important your child's safety and comfort are to you, and every preparation step is performed with this as our priority.
Gentle Anaesthesia and Catheter Access
General anaesthesia is administered by our experienced paediatric anaesthesiologist so your child is completely comfortable and still throughout the procedure. A thin catheter is gently passed through the groin vein under continuous X-ray and echocardiographic guidance.
Precise Device Deployment
The chosen occluder device is carefully guided through the catheter and positioned precisely across the PDA opening under live imaging guidance. Once your cardiologist confirms the device is perfectly centred and the defect is fully covered, the device is deployed to permanently seal the abnormal connection.
Confirming Complete Closure
Echocardiography and fluoroscopy are used immediately after device deployment to verify that the PDA is completely sealed, blood flow is normal, and the device is securely positioned without affecting surrounding heart structures. This confirmation step protects your child's long-term cardiac health.
Recovery and Discharge Planning
Your child is monitored in the recovery area and paediatric ward before a repeat echocardiogram confirms successful closure. Our team provides you with clear instructions on activity restrictions, antiplatelet medications, follow-up appointments, and warning signs to watch for at home.
What to Expect
PDA Device Closure is performed under general anaesthesia in children or light sedation in older patients to ensure complete comfort. A catheter is inserted through the groin vein and guided to the heart under X-ray and echocardiographic guidance, and the occluder device is precisely deployed to seal the PDA permanently. The procedure takes 45 to 75 minutes and most patients are monitored overnight and discharged the following day after a confirmatory echocardiogram.
Recovery
After PDA Device Closure, rest at home for 3 to 5 days avoiding all vigorous physical activity while the device settles. Take prescribed antiplatelet medications as directed for 6 months — never stop these early without medical advice. Attend echocardiogram follow-ups at 1 month, 3 months, and 1 year to confirm complete closure. Contact your cardiologist immediately if there is fever, chest pain, difficulty breathing, or infection at the catheter site.
