Peripheral Pulmonary Stenosis can be described as the flow of blood from the right ventricle to the pulmonary artery is being obstructed. This kind of defect can occur due to narrowing of stenosis a couple of times in the way of the right ventricle to the pulmonary artery. The primary 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. Doctors found the obstruction at the valve itself in most cases, known as valvar pulmonary stenosis. In 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 when the pulmonary valve gets narrow from the opening and slows the blood flow all over the heart—the place where the pulmonary valve is located in between the right ventricle and the pulmonary arteries. There are rare cases of pulmonary stenosis in adults because mainly pulmonary valve stenosis develops before or during the child’s birth.
The symptoms that affect and treatment of pulmonary valve stenosis vary upon the range of this disorder as pulmonary stenosis can occur from mild to worst. There may be no symptoms in the case of mild pulmonary stenosis, and it is even not a surgical treatment. But severe pulmonary stenosis may get worst and require surgery. In past decades, because technology got so advanced, the rate of successful surgery got higher. Therefore, people affected with Peripheral Pulmonary Stenosis don’t need to get worried so much now.
Symptoms of Pulmonary Stenosis
As we have mentioned above, the signs and symptoms of pulmonary valve stenosis vary in the range of the disorder. People with mild pulmonary stenosis usually don’t have signs 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:
- A heart murmur is one of the most common symptoms of this disorder. When a doc hears the heartbeat of your heart through a stethoscope, then he may notice any abnormal and unwanted sound from heat which is because of turbulent blood flow
- Fatigue – You may be in a situation when you will shorten of breath after doing any exercise or 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 perfect for curing it starting; otherwise, it can be a 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 short just after doing any physical activity and even after feeding.
- Your baby will have recurring chest pain, which will make him cry.
- If you have Peripheral 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 no identified or specified causes of pulmonary stenosis, but according to researchers and doctors, it was concluded that pulmonary stenosis is a kind of disease that develops during fetal growth because of any hormone or genetic problem.
Pulmonary stenosis mainly occurs when the pulmonary valve doesn’t develop properly during fetal development or 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 leading causes of developing pulmonary stenosis in children.
How does a standard pulmonary valve work?
The pulmonary valve is the combination of three thin tissues, called cusps which are 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 blood flow towards the lungs, it automatically gets closed to prevent blood from flowing into the heart’s right ventricle.
What happens in the case of pulmonary stenosis?
As we have mentioned above in this article, the pulmonary valve is the combination of three thin tissues, called cusps. In the case of pulmonary stenosis, one or two of the cusps may get defective or become too thick. Or maybe, in some cases, the cusps are not separated from each other appropriately. And if this kind of situation occurs, then the pulmonary valve doesn’t open properly and sufficiently, and the blood flow gets restricted.
How can it be diagnosed in children?
Often, Peripheral Pulmonary Stenosis is diagnosed in childhood. However, during the regular check-up, if your doctor hears any unwanted murmur sound from your heart and suspects pulmonary stenosis, your doctor will use various tests and scans to confirm the diagnosis.
Echocardiogram: –
This is one of the most used procedures in any heart disorder, and in this procedure, sound waves get back or bounce back from your heart. In addition, this procedure produces images that you can see through a video screen. This prefers the best procedure test for children with no harm, and it is also helpful in knowing the size of the pulmonary valve—Doc and seeing the severity of the stenosis.
Electrocardiogram:
This is another procedure the doc can perform; this doc will place patches with wires on the children’s 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 beneficial to determine if the muscular wall is thickened.
Other imaging tests: –
Doc may also do further imaging tests, including MRI and CT scans used to confirm the diagnosis of the pulmonary valve.
