Pulmonary Stenosis

Pulmonary stenosis occurs in and around the pulmonary valve.  The stenosis can be in the valve or in the heart muscle just under the valve.  In normal blood flow, the blood leaves the right ventricle and passes through the pulmonary valve.  The blood goes out to the lungs. 

 

Symptoms

 

The size of the narrow place will decide treatment and symptoms.  Some infants will have trouble with eating and weight gain.  Often a murmur is heard on exam.  Some children will have no symptoms and some will have shortness of breath.  Infants with severe pulmonary stenosis can be very ill after birth.  They may need treatment right away.  An ultrasound of the heart (echocardiogram) as well as the exam helps the doctor decide what type of treatment is best for your child.  The echocardiogram will look at the size of the narrow place and the size of the right ventricle.  The right ventricle may have to work harder to pump blood through the narrow place.  The right ventricle can become enlarged or thickened. 

 

Treatment

 

Some children can have their pulmonary stenosis treated in the cardiac catheterization lab.  A doctor will pass a balloon thru the valve.  The balloon will inflate to open up the narrow place.  Then, the balloon is removed.  Some children need surgery to repair their valves.  This will be explained to you by your child’s cardiologist and the surgeon.
