Peripheral Pulmonary Stenosis Symptoms and Causes in Children

5 min read

Pulmonary stenosis can be described with the situation when the flow of blood from the right ventricle to the pulmonary artery is being obstructed.  This kind of defects can be occurring due to narrowing of stenosis for a couple of time in the way of the right ventricle to the pulmonary artery. The basic area where it gets defect is included present tissues below the pulmonary valve, at stenosis of the valve, or stenosis of the pulmonary artery above the valve. In most of the cases, doctors found that the obstruction at the valve itself, which is known as pulmonary valvar stenosis. In the situation of pulmonary stenosis, pressure on the right ventricle gets high because it works more than its strength to eject blood into the pulmonary artery.

Pulmonary valve stenosis is a condition in which the pulmonary valve gets narrow from the opening and slows the blood flow all over the heart. The place where pulmonary valve located in between the right ventricle and the pulmonary arteries. There are rare cases of pulmonary stenosis in adults because mostly pulmonary valve stenosis develops before or during the birth of the child.

The symptoms affect and treatment of pulmonary valve stenosis vary upon the range of this disorder such as pulmonary stenosis can occur from mild to worst. In the case of mild pulmonary stenosis, there may be no symptoms and it is even not a surgical treatment. But severe pulmonary stenosis may get worst and require surgery. In past decades because the technology got so advance the rate of successful surgery get higher and people who are affected with pulmonary valve stenosis don’t need to get worried so much now.

Symptoms of Pulmonary Stenosis

As we have mentioned above that the signs and symptoms of pulmonary valve stenosis vary in the range of the disorder. People with mild pulmonary stenosis usually don’t have sign and symptoms. But people who have significant stenosis may notice these signs and symptoms while doing any activity. Pulmonary stenosis signs and symptoms may include:

  • Heart murmur – this is one of the most common symptoms on this disorder when doc will hear the heartbeat of your heart through stethoscope then he may notice any abnormal and unwanted sound from heat which is because of turbulent blood flow
  • Fatigue – You may be in the situation when you will shorten of breath after doing any exercise of physical activity.
  • You may have severe chest pain again and again.
  • You can lose your consciousness or may feel fainting in front of your eyes.

Signs and Symptoms in the child

Symptoms in an affected child may be different from an adult. In the case of pulmonary stenosis, it is very good to cure it in starting otherwise it can be life-threatening disorder. There are some common signs that you notice if your child is suffering from this disorder:-

  • You will feel that his breath is being short just after doing any physical activity and even after feeding.
  • Your baby will have regular chest pain which will make him cry.
  • If you have pulmonary stenosis or another heart problem, prompt evaluation and treatment can help reduce your risk of complications.

Causes of Pulmonary Stenosis in children

Yet, there are not any identified or specified causes of pulmonary stenosis but according to researcher and doctors, it was concluded that pulmonary stenosis is kind of disease which develop during the fetal growth because of any hormone or genetic problem.

Pulmonary stenosis mainly happens or develops when the pulmonary valve doesn’t develop properly during fetal development or while pregnancy. It is also happening in the case when the upcoming baby already has the other condition of congenital heart abnormalities. So, these are the main causes of developing pulmonary stenosis in children. 

How normal pulmonary valve works?

The pulmonary valve is the combination of three thin tissues which is called cusps which is placed in a circle. All the time when human heartbeat then the valve get opens to let the blood flowing in the direction of the pulmonary artery and the towards the lungs. Including this procedure, after the flow of blood towards the lungs, it automatically gets closes to prevent blood flowing into the heart’s right ventricle.

What happens in the case of pulmonary stenosis?

As we have mentioned above in this article that pulmonary valve is the combination of three thin tissues which is called cusps and in case of pulmonary stenosis one or two of the cusps may get defective or become too thick. Or maybe in some case the cusps not separated from each other properly. And if this kind of situation occurs then pulmonary valve doesn’t open properly and sufficiently, and due to which the blood flow gets restricted.

How it can be diagnosed in children?

Often, pulmonary stenosis is diagnosed in childhood. During the regular check-up, if your doctor hears any unwanted murmur sound from your heart and suspect’s pulmonary stenosis, then your doc will use a variety of tests and scans to confirm the diagnosis.

Echocardiogram: – This is one of the most used procedures in any kind of heart disorder and in this procedure sound waves get back or bounce back from your heart. This procedure produces images which you can see through a video screen. This prefers the best procedure test for children with no harm and it is also useful for knowing the size of the pulmonary valve. Doc and also seen the severity of the stenosis.

Electrocardiogram: – It is another procedure doc can perform, in this doc will place patches with wires are placed on children chest, wrists, and ankles. In this procedure, electrode waves regulate the electrical activity in your heart, which is recorded on paper by a doctor. This procedure is really helpful to determine if the muscular wall is thickened.

Other imaging tests: – Doc may also do further imaging test which includes MRI and CT scans which are used to confirm the diagnosis of the pulmonary valve.
