Fluid around the heart? Let's talk about Pericardial Effusion!

Have you ever felt a strange tightness in your chest, a little difficulty breathing? Or maybe a doctor has told you that there is something like fluid accumulating around your heart. That is what we are going to talk about today. This is medically called `(Pericardial Effusion)`. Don't be afraid, we will talk about this simply, in a way that you can understand.

What does this fluid filling around the heart mean? (Pericardial Effusion)?

Simply put, `(Pericardial Effusion)` is the accumulation of fluid in the thin sac that surrounds your heart, called the `pericardium` . Think of your heart as a valuable object that has a small sac around it to protect it. This is where fluid can build up. There can be many reasons for this. Sometimes, this condition can be caused by infections, injuries, or other illnesses.

However, if this fluid buildup becomes too much all at once , or too quickly , it can cause the heart to beat faster. In that case, it can be a life-threatening situation that requires emergency medical treatment .

Now look, as this fluid builds up slowly, the sac around the heart, the pericardium, gradually expands and makes room for the extra fluid. But if the fluid fills up all at once, the sac doesn't have time to expand and expand. What happens then? The fluid puts a lot of pressure on the heart. The chambers of the heart fill up with blood and don't have time to expand. Because of this, the amount of blood pumped by the heart decreases. Then the other organs in the body don't get the blood they need.

To put this in a simpler way, imagine that you are inflating a balloon inside a plastic bottle. Here, your heart is the balloon, and the bottle is the pericardium. When the bottle is empty, there is plenty of room for the balloon to inflate, right? But if you start filling the bottle with water, the space available for the balloon to inflate decreases. If you keep filling the bottle with water, eventually the balloon will not be able to inflate at all. That is what happens in `(Pericardial Effusion)`.

How common is this condition?

Pericardial effusion is actually a relatively common condition. It can occur in anyone of any age and background, as there are many causes.

What complications can this cause?

One of the most dangerous complications of pericardial effusion is cardiac tamponade . Normally, there is a thin layer of fluid between the inner wall of the pericardium and the heart. Just like we put bubble wrap around a fragile item in a box, this layer of fluid provides a cushioning effect to the heart.

But in a condition called ``Cardiac Tamponade'', that fluid builds up too much, preventing the heart from filling with blood and working properly. If this is not treated quickly, the heart can stop and even cause death within a few hours.

But `(Cardiac Tamponade)` is not the only complication of this. When the amount of blood pumped by the heart decreases, the heart starts beating faster to compensate for the loss. But over time, the heart cannot work this fast. Then a condition called `Cardiogenic Shock` can develop. This too can be fatal if left untreated.

What are the symptoms of this?

If you have a small amount of fluid buildup, you may not notice any symptoms. Symptoms are more likely to occur if the fluid buildup occurs quickly, if the amount of fluid is very large, or if you develop the condition we talked about earlier, ``Cardiac Tamponade''. The main symptoms are:

• Difficulty breathing (sometimes called ``Dyspnea'')
• Chest tightness or pain
• Rapid heartbeat or chest pain (palpitations)
• Lightheadedness or dizziness
• Fainting or loss of consciousness (`(Syncope)`)
• Feeling very tired (Fatigue)
• Restlessness, confusion, or behavioral changes (these are caused by decreased blood flow to the brain)
• Cyanosis ( blue/gray discoloration of the lips or under the fingernails due to low oxygen in the blood)

If the amount of this fluid is too high, it can put pressure on surrounding tissues or nerves, causing symptoms such as:

• Difficulty swallowing (`(Dysphagia)`)
• Hiccups
• Coughing or hoarseness

Why is this happening? What are the reasons?

In developed countries, most of the time, the exact cause of Pericardial Effusion cannot be found. However, in developing countries, especially in a country like Sri Lanka, Tuberculosis is a major cause of this.

There are many causes of `(Pericardial Effusion)`. Most often, it occurs with inflammation of the heart, that is, with the condition `Pericarditis` .

Other reasons can be called:

• Infections: Can be caused by viruses, bacteria (for example, HIV and tuberculosis), fungi, or parasites. However, pericardial effusion itself is not contagious.
• Cancer: Tumors that form in the heart or cancer cells that spread from elsewhere in the body can damage the heart lining.
• Immune system diseases or inflammatory conditions: For example, diseases such as `(Lupus)`, `(Rheumatoid Arthritis)` or `(Sjögren's syndrome)`.
• Hormone-related problems: An example is `(Hypothyroidism)` (the thyroid gland does not produce enough thyroid hormone).
• Trauma: Chest injuries, severe blows such as in car accidents, stabbings, and gunshot wounds.
• Heart disease or circulatory system problems: heart attack, heart valve disease, separation or tearing of the layers of the aorta (Aortic Dissection).
• Medical causes: After heart surgery, after radiation therapy for cancer, or as a side effect of some medications.
• Other: This can also occur with conditions such as heart failure, chronic kidney disease, kidney failure, or liver cirrhosis.

How do you diagnose this? (Diagnosis)

If you have symptoms, a doctor will determine whether you have Pericardial Effusion after reviewing your symptoms, your medical history, medical tests, and a physical examination.

If you don't have symptoms, it's often discovered incidentally. For example, it may be found on a chest X-ray done for another reason.

If a doctor suspects a condition called ``Pericardial Effusion,'' they may perform several tests, including:

• Electrocardiogram (EKG): View the electrical activity of the heart.
• Imaging tests:
• Echocardiogram: This is the main and most important test to diagnose this condition. It is like an ultrasound scan of the heart.
• Chest X-ray.
• Chest CT scan.
• MRI of the heart.

Once a diagnosis of pericardial effusion is made, the doctor may order blood tests to determine the cause. For example:

• Complete Blood Count (`CBC`).
• Troponin test.
• B-type natriuretic peptide test.
• Thyroid-stimulating hormone test.
• Immune system tests (to look for diseases or inflammatory conditions of the immune system).

Sometimes, the fluid removed from the pericardium can be tested to determine the cause of this condition.

What is the treatment for this?

The treatment you receive will depend on how serious your condition is and what the cause is.

• If the fluid level is low, but there are no symptoms: If the fluid level is decreasing or staying the same, you may not need any treatment. In such cases, your doctor will likely monitor the fluid level and only treat if symptoms develop or there are signs of another problem.
• If the fluid is increasing rapidly, if there are symptoms, or if it is due to a serious cause (especially an injury or cancer), you may need treatment right away.

If the `(Pericardial Effusion)` is large, it can cause `(Cardiac Tamponade)`, which is a condition that requires emergency medical treatment . In such cases, the fluid will not go away on its own without being removed. The following are the treatments that can be done:

• Pericardiocentesis: After numbing a specific area of ​​the chest, with the help of an imaging technique such as echocardiography or fluoroscopy, a doctor inserts a needle into the pericardium. The extra fluid is then drained. A thin tube may be left in place for several days until all the fluid is gone.
• Surgery: In some cases, surgery is the best way to remove excess fluid from the pericardium. This can be an emergency procedure, or it can be a planned procedure (when the fluid buildup is symptomatic but is slowly increasing and not dangerous). A common procedure for this is video-assisted thoracic surgery (VATS) . This involves creating a "window" in the pericardium (a "pericardial window"), which allows the fluid to drain into the large cavity around the lungs (the "pleural cavity") without filling the pericardial space.

In cases where the above treatments are not necessary and are not dangerous, a doctor can often manage it with medication or other treatments. The treatment depends on the underlying cause. Some examples:

• Antibiotics for infections like tuberculosis.
• Anti-inflammatory drugs reduce inflammation and swelling.
• Chemotherapy and radiation therapy are recommended for those with pericardial effusion due to cancer.
• Diuretics and other medications for those who have developed pericardial effusion due to heart failure.

What are the side effects or complications of the treatment?

The side effects that may occur with treatment for `(Pericardial Effusion)` depend on the treatment or medication you are receiving. Your doctor can best explain to you the possible side effects of the medications you are taking.

One possible complication is pericardial decompression syndrome . This can happen when you have surgery or a procedure to treat pericardial effusion. Although it is uncommon, it is a serious, life-threatening condition. It often happens if a large amount of fluid is removed too quickly. To prevent this, your doctor may remove the fluid slowly.

How quickly will I recover after treatment? How long will it take to recover?

The time it takes for you to recover and recover depends on these factors:

• The reason for the accumulation of fluid.
• Severity of fluid accumulation.
• The treatment you received.
• Your overall health and whether you have any other related medical conditions.

If you have symptoms of `(Cardiac Tamponade)`, you should start to feel better as the fluid is removed and the pressure on your heart is reduced. In general, your doctor can give you the best idea of ​​how long it will take to recover and when you should start to feel better.

Can Pericardial Effusion be prevented?

Pericardial effusion is an unpredictable condition, so it is often impossible to prevent it. However, you can reduce your risk by avoiding situations that may cause it. For example:

• Leaving an infection untreated for too long.
• Engaging in sports or outdoor activities that carry a high risk of injury without using protective equipment.

What should I expect if I have Pericardial Effusion?

Pericardial effusion is usually a serious condition. But it is not always a medical emergency. Whether it is a life-threatening emergency or not depends on the cause, the amount of fluid, and the rate at which the fluid fills the pericardium.

When fluid builds up quickly, there is less fluid to cause a dangerous condition like `(Cardiac Tamponade)`. This is because the pericardium does not have time to make room for more fluid. When `(Pericardial Effusion)` develops slowly, it can take weeks or even months to become a problem.

One factor that determines whether a pericardial effusion is serious is why it occurred in the first place. Whether it is caused by injury, heart disease, circulatory problems (or any other cause that can cause fluid to build up quickly), it requires prompt treatment to prevent dangerous complications like cardiac tamponade.

How long does Pericardial Effusion last?

Large fluid collections and rapidly increasing fluid collections are serious conditions that require immediate medical attention. Especially in emergencies, they should not last longer than they should be recognized and treated.

Chronic fluid accumulation, especially small, asymptomatic ones, can last for weeks, months, or even years. Your doctor may recommend regular follow -up appointments to check the amount of fluid and whether it is a risk to your health.

Outlook for Pericardial Effusion

Doctors can often treat pericardial effusions. Sometimes, depending on how severe they are and what caused them, they can even be cured.

In general, pericardial effusions of unknown cause have a good prognosis. Pericardial effusions caused by injury or cancer are more likely to cause complications and are usually more difficult to treat. Pericardial effusions associated with cancer or HIV/AIDS have a lower survival rate.

How do I take care of myself?

If you have Pericardial Effusion, it's important to be aware of any symptoms or changes in your overall health. It's also essential to follow your doctor's instructions, especially regarding taking medications and managing your recovery time.

When should I see my doctor?

If necessary, your doctor will schedule follow-up visits to monitor your condition. He will also give you instructions on how to manage your symptoms and when you should call his office.

When should I go to the Emergency Department (ETU) ?

If you have any of these symptoms, you should go to the hospital emergency room immediately. These may be signs of a condition called ``Cardiac Tamponade``:

• Chest pain.
• Difficulty breathing or rapid breathing.
• Changes in skin color, especially paleness, grayness, or blueness.
• Dizziness, vertigo or vertigo .
• Palpitations.
• A pulse rate of more than 100 beats per minute at rest (Tachycardia).

What questions should I ask my doctor?

You may want to ask your doctor these questions:

• What is the cause of my `(Pericardial Effusion)`?
• What is the best treatment for me?
• What is the chance of a pericardial effusion recurring?
• What is my prognosis?

What is the difference between `(Pericardial Effusion)` and `(Pleural Effusion)`?

Pleural effusion is similar to pericardial effusion, but it occurs in a different part of the chest. The pleural cavity is the sac that surrounds your lungs. Pleural effusion is the accumulation of fluid in that space. A pleural effusion can cause your lungs to not expand properly, making it difficult to breathe.

When you have trouble breathing, when your chest hurts, you just want relief. You may not even know why you have a pericardial effusion, a fluid-filled sac around your heart. Whatever the cause, you should feel better after treatment. Don't hesitate to ask your doctor about anything that's unclear to you.

Take-Home Message
