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
