Do you sometimes feel a little tightness in your chest, difficulty breathing, or even a little bit of exertion? These could be signs of a problem with your pulmonary valve, which acts like a small gate in your heart. Don't worry, we'll talk about this in detail and very simply today. Understanding this will give you a great sense of relief.
What is Pulmonary Valve Disease?
Simply put, Pulmonary Valve Disease is any condition in which the Pulmonary Valve, a very important valve in our heart, does not work properly. Think of it like a gatekeeper. It is the one that allows blood to pass from the lower chamber on the right side of your heart, the Right Ventricle , to the main artery that carries blood to the lungs, the Pulmonary Artery . When the blood reaches the lungs, it picks up new oxygen. Then, that oxygen-filled blood is distributed throughout the body, giving life to our cells.
So, if there is a problem with this pulmonary valve, it becomes difficult for your blood to reach your lungs. What happens then? The tissues, cells, and organs of the body receive oxygen late. This is like a water pipe that becomes clogged and the water flow slows down. This is why we have various problems.
What are the types of Pulmonary Valve Disease?
There are three main types of pulmonary valve disease. Let's see what they are, very simply:
1. Pulmonary Valve Regurgitation: This is when the valve does not close properly, and some blood leaks backward. Think of it like a water faucet that is not closed properly and leaks water drops by drops. Then the heart has to work harder to push that blood back forward.
2. Pulmonary Valve Stenosis: This is when the valve becomes narrow, or more accurately, blocked. This narrows the path for blood to flow. Think of it like squeezing a water pipe, which narrows the path for water to flow. This causes the heart to have to work harder to push the blood forward.
3. Pulmonary Atresia: This is a serious condition. This is when a baby is born with a valve that is not formed or is not developed properly . This is a congenital heart disease.
How common is Pulmonary Valve Disease?
Let's see how common these diseases are.
Pulmonary valve regurgitation is actually quite common . Some people are born with a slightly different valve structure. People with these physiological differences are more likely to develop pulmonary valve regurgitation. However, most of the time it is very mild. That doesn't mean it's something to be afraid of or treat. For most people, it's not a big deal.
Pulmonary valve stenosis (narrowing of the valve) occurs in about 7% of people with congenital heart disease.
In the United States, approximately one in 7,000 babies is born with pulmonary atresia (absence of the valve at birth). Although the statistics in our country are not exact, this is a condition that needs to be taken into account.
What could be the symptoms of this disease?
Symptoms of Pulmonary Valve Disease can vary from person to person. Some people may experience these symptoms:
- Chest pain: It feels like your chest is being squeezed, sometimes even when you breathe.
- Fatigue: Just feeling tired, a feeling of being so weak that you can't do anything.
- Lightheadedness: Feeling dizzy, sometimes even fainting.
- Shortness of breath: Difficulty breathing, wheezing, even when walking a little or climbing stairs.
- Inability to exercise: I don't feel like running, jumping, or exercising like I used to, and even if I do, I get tired quickly.
But remember, people with mild stenosis or mild regurgitation may not have any symptoms. That's why medical tests are important.
If a baby has Pulmonary Atresia, they may have difficulty breathing, difficulty feeding, are often sleepy, and sometimes have a blue color to their skin (Cyanosis). This is something that you should pay close attention to. As parents, if you notice any of these symptoms, you should see a doctor immediately.
What are the causes of Pulmonary Valve Disease?
The causes of this disease vary depending on the type of disease. Let's see how it happens.
- Causes of Pulmonary Stenosis: In most cases, it is difficult to find a specific cause for this. However, this condition can occur due to certain genetic disorders or if the mother contracts a disease like rubella during pregnancy. Rubella is a disease that can affect the fetus, so it is important to be careful during pregnancy.
- Causes of Pulmonary Regurgitation: This can have several causes. For example, high blood pressure (especially pulmonary hypertension), infections of the lining of the heart (endocarditis), rheumatic fever, etc. It can also be caused by certain congenital heart issues or their treatments. This condition is especially common in people who have had a heart condition called Tetralogy of Fallot.
- Causes of Pulmonary Atresia: In many cases, the exact cause of this condition is unknown. However, it is thought to be caused by changes in a fetus' genes, exposure to environmental toxins during pregnancy, or something the mother takes.
What are the possible complications of this disease?
Pulmonary Valve Disease causes the right ventricle of your heart to have to work harder to pump blood to your lungs. This can damage your heart and cause it to enlarge. Although rare, if this condition becomes severe, it can lead to heart failure . This means that your heart is unable to pump enough blood to your body.
Children with Pulmonary Atresia can develop liver disease and abnormal heart rhythms, so prompt treatment is important.
How is this disease diagnosed?
When you go to see a doctor, if he or she hears an abnormal sound when listening to your heart (with a stethoscope ) , it could be a sign of either Pulmonary Regurgitation or Pulmonary Stenosis. This murmur is an abnormal sound made by blood flowing through the valves.
What tests are done to diagnose this condition?
The doctor may perform the following tests to confirm pulmonary valve disease:
- Fetal Echocardiogram: This helps detect conditions like Pulmonary Atresia before the baby is born.
- Echocardiogram (Echo): This can look at many things, such as the function of the heart and the condition of the valves. It is used to detect `Atresia`, `Stenosis` or `Regurgitation`. It is like taking a picture of the heart using sound.
- Pulse Oximetry: This is used to check the oxygen level in the blood in cases of `atresia`. It is a simple test that is done by placing a clip on the finger.
- Cardiac Catheterization: This is done in cases of `Atresia` or `Stenosis`. A method in which a small tube is passed through a blood vessel into the heart to measure the pressure and, if necessary, to treat it.
- Electrocardiogram (EKG/ECG): This is done to check the electrical activity of the heart in cases of `Atresia` or `Regurgitation`.
- Heart MRI (Magnetic Resonance Imaging): This helps to take detailed images of the heart in cases of `Stenosis` or `Regurgitation`.
- Chest X-ray: This helps to see the size of the heart and the condition of the lungs in the case of `regurgitation`.
How is Pulmonary Valve Disease treated?
Treatment for this varies depending on the condition you have. Sometimes it can be controlled with medication, sometimes it can even involve surgery.
Specific medications and treatments
There are several treatments for pulmonary valve disease:
- Balloon Valvuloplasty: This is done to widen a narrowed pulmonary valve. This is done by inserting a small balloon-like device into the valve and inflating it.
- Medication or stent placement (for ``Atresia``): This is done to keep the ``Ductus Arteriosus``, a blood vessel that closes quickly after a baby is born, open. Keeping this tube open helps blood flow to the lungs.
- Diuretics: These medications are given to prevent fluid retention in the body due to heart failure caused by blood leaking from the valves. They cause the body to excrete excess water through urine.
- Medicines for Pulmonary Hypertension (high blood pressure in the lungs) or Endocarditis (heart infection) (for Regurgitation): Medicines are given to control these conditions.
- Transcatheter procedure or open-heart surgery: These procedures are used to repair a leaking valve or to insert a new valve.
Complications/side effects of treatment
Some babies may have difficulty eating after surgery, and may need to be fed through a small tube through their nose (tube feeding).
After a valve replacement, your child will need to take antibiotics when they have dental work. These medications reduce the risk of developing a heart infection called endocarditis.
After a pulmonary valve is repaired, it can leak again, and the doctor may have to widen or replace it.
As with any surgery, there is a small chance of infection or bleeding, but doctors are very careful about that.
How long does it take to recover from treatment?
After surgery for `Pulmonary Atresia`, your child will be in the hospital for about a week or two. After surgery for `Pulmonary Valve Regurgitation`, recovery can take weeks, even months. After `Valvuloplasty` for `Pulmonary Stenosis`, you will need to avoid strenuous activities for about a week.
What can you expect if you have Pulmonary Valve Disease?
Your experience with this disease may be different from someone else's. Some people have very few symptoms and may not need surgery. Others may need more than one pulmonary valve surgery in their lifetime.
Outlook for pulmonary valve disease
The outlook for children who have valvuloplasty for pulmonary valve stenosis is very good . They usually do not need anything more than regular check-ups with a pediatric cardiologist. Some people may need to have their valve widened again after about 15 years.
Pulmonary atresia can be fatal if left untreated, but many children survive to adulthood after surgery.
The outlook for people with mild or moderate pulmonary valve regurgitation is good. For people with severe disease, the outlook depends on how quickly they receive treatment.
How can I reduce the risk?
You cannot reduce the risk of your baby developing Pulmonary Valve Disease, a condition that occurs without a known cause. But if you are planning to become pregnant, make sure you have received the Rubella Vaccine.
You can reduce your risk of developing Pulmonary Valve Regurgitation by avoiding conditions that cause it, such as Pulmonary Hypertension, Endocarditis, and Rheumatic Fever.
How do I take care of myself?
Manage the things you can control and keep your heart healthy.
- Control your blood pressure and cholesterol levels.
- Avoid tobacco products completely.
- Exercise regularly. Even just walking for 30 minutes a day is good.
- Eat fruits, vegetables, and foods low in or no saturated fat. Our local diet is very suitable for this.
When should I see my doctor?
Don't miss your follow-up appointments with your cardiologist. He or she can check to see if your valve is still working properly. He or she may also want to repeat some of the tests used to diagnose you in the first place. For example:
- Echocardiogram (Echo)
- CT scan (Computed Tomography - CT scan)
- Heart MRI
- EKG (Electrocardiogram - EKG)
When should I go to the Emergency Department (ETU) ?
If you have any of these symptoms, go to the emergency room immediately:
- Frequent fainting episodes.
- Severe difficulty breathing.
- Feeling like your heart is beating fast (Heart Palpitations).
- Signs of infection or bleeding, such as fever and blood in the stool, after surgery.
What questions should I ask my doctor?
You can ask the doctor questions like these:
- What is the best treatment for me (or my child)?
- Do you know the cause of my (or my child's) Pulmonary Valve Disease?
- How often do I (or my child) need to come see you?
- Are there support groups for parents of children with heart disease?
Finally, take-home message
It's normal to feel a little uneasy when you learn that your child (or your own heart) has Pulmonary Valve Disease. But don't worry. Cardiologists deal with these types of valve problems all the time. They can use their experience to determine the best treatment for you or your child.
Don't be afraid to ask questions about anything you don't understand. Go for all the tests your doctor orders, and take all the medications you're given on time. You're not alone, and there are doctors, nurses, and your family to help you on this journey. Staying positive is also very important for a speedy recovery.
