Pediatric Cardiology - Pulmonary Stenosis

​​​​​​​​​​​​​​​​​​​​​​Pulmonary Stenosis (PS) is a congenital heart defect (a child is born with it) and occurs when the valve between the right ventricle and the pulmonary artery doesn't open all the way. 

It can also occur when the area above or below the valve is too narrow. As a result, blood flow to the lungs is blocked, which can lead to certain heart problems over time. 

Marshfield Clinic has Pediatric Cardiologists to diagnose and treat any child with a congenital heart defect.

Treatments

Mild or moderate PS usually requires no treatment, but regular visits with a pediatric cardiologist are needed to make sure that the narrowing at or near the valve doesn't worsen over time. 

Severe or critical PS does require treatment and is most often treated with a procedure called balloon valvuloplasty.

Balloon Valvuloplasty
Balloon valvuloplasty is a procedure done on the heart using a thin, flexible tube called a catheter. 

The catheter is inserted into a blood vessel in the groin. With the help of live x-rays, the catheter is advanced up through the blood vessel until it reaches the heart. 

A tiny balloon at the end of the catheter is then inflated one or more times in the pulmonary valve, which opens the valve leaflets. Then the catheter and balloon are removed.

Surgery
Using open heart surgery, the valve is replaced or repaired.​
