What Is Pulmonary Artery Stenting?
The pulmonary arteries carry blood from the heart to the lungs. They can be narrowed from birth, as part of certain genetic syndromes, or after heart surgery such as Tetralogy of Fallot repair, the arterial switch or the Glenn operation. Narrowing reduces blood flow to part of the lung and increases pressure in the right ventricle.
Balloons alone often fail because the artery wall recoils. A stent — a metal mesh tube mounted on a balloon — is expanded inside the narrowed segment to hold it open. Stents can be redilated later as the child grows, often avoiding the need for further surgery.
Better Lung Perfusion
Restores balanced blood flow to both lungs.
Right Heart Relief
Reduces pressure and strain on the right ventricle.
Future-Proof
Stents can be expanded further during later catheter procedures.
When Is It Recommended?
Pulmonary artery stenting may be recommended when:
- A branch pulmonary artery is significantly narrowed
- Lung scans or MRI show reduced flow to one lung
- Right ventricular pressure is raised
- Narrowing develops after Tetralogy of Fallot repair or other surgery

Conditions Covered
Heart conditions commonly assessed or treated with this service.
Post-Operative PA Stenosis
After Tetralogy of Fallot repair, arterial switch or shunt surgery.
Single-Ventricle Circulation
Narrowing in Glenn or Fontan pathways.
Syndromic PA Stenosis
Associated with Williams or Alagille syndrome.
Congenital Branch Stenosis

How It Is Performed
What happens on the day, explained simply so you know what to expect.
- 1Step 01 / 05
Anaesthesia
Under general anaesthesia, oxygen levels and breathing are watched closely, as blood flow to the lungs is being treated.
- 2Step 02 / 05
Vein Access
Catheters are introduced through the groin vein.
- 3Step 03 / 05
Angiography
The narrowed segment is measured precisely.
- 4Step 04 / 05
Stent Deployment
A balloon-mounted stent is expanded within the narrowing.
- 5Step 05 / 05
Result Check
Pressure and angiography confirm improved flow.

Frequently Asked Questions
Answers to common questions about Pulmonary Artery Stenting.
Why use a stent instead of just a balloon?
+
Many pulmonary artery narrowings spring back after ballooning. A stent holds the vessel open, giving a more lasting result.
Will the stent limit growth of the artery?
+
Stents are chosen so that they can be expanded further during later catheter procedures, allowing the artery to keep pace with growth.
Can stenting be done after heart surgery?
+
Yes. Treating narrowings after surgery is one of the commonest reasons for pulmonary artery stenting, and it often avoids another operation.
How long will my child need medicines?
+
Antiplatelet medicine is usually given for a period after stenting. Dr. Bharath will advise the duration based on your child's condition.
Is the stent permanent?
+
Yes. The stent stays in place permanently and becomes covered by the vessel lining. It can be expanded further during later catheter procedures as your child grows.
What symptoms improve after stenting?
+
Children often have better exercise tolerance and, in some circulations, improved oxygen levels. Pressure on the right side of the heart also reduces, which protects heart function over time.
