This procedure is done in cath lab.

In this procedure, we sedate the child. After sedation, we generally take a groin vein known as femoral vein.

With the help of wires, tubes, catheters etc, we cross the pulmonary valve under fluoroscopy guidance.

After crossing the valve, we placed a suitable wire across the valve.

Then we select a proper sized balloon depending on size of pulmonary valve annulus.

We track the selected balloon over the pre-selected wire and then by inflating the balloon across the valve, we relieved the obstruction.

Indication of ballooning

  • Severe or critical PS in newborn
  • Severe PS in infants and children when gradient across the valve is more than 60 mm Hg

Risk associated with balloon dilatation

  • Complications are more in newborn.
  • It can be pulmonary valve leak, balloon rupture, infection etc.

Stay in hospital required?
Yes, maximum 48-72 hours
