Is it a balloon-like bulge in the wall of the heart? Let's talk about this (Ventricular Aneurysm)!

Have you ever heard that a part of the heart wall can become weak and bulge like a balloon? This is a condition that can actually happen to some people. It can happen especially after a heart attack. So, today we will talk about this condition called `(Ventricular Aneurysm)` in a simple way, so that you can understand it.

What is this `(Ventricular Aneurysm)`? To put it very simply...

Okay, first let's see what this is. You know that our heart has four main chambers. The two chambers below these are the ones that pump blood to the body and lungs. Those lower chambers are what we call `(Ventricles)` . So, when a place in the wall of one of these `(Ventricle)`, that is, one of the lower chambers of the heart, becomes weak and bulges out like a balloon, we simply call it `(Ventricular Aneurysm)`. Think of it like a sidewall of a car tire becomes weak and bulges out like a bubble. When the heart pumps blood, that weak spot bulges out.

This can be dangerous, because sometimes the swelling can rupture . If this happens, it is a life-threatening emergency and requires immediate medical attention.

Are there types of Ventricular Aneurysm?

Yes, doctors recognize two main types of Ventricular Aneurysm.

1. True Ventricular Aneurysm: This occurs when a portion of the heart wall, often due to a heart attack (Myocardial Infarction), dies and weakens. The weakened wall can then bulge out and form a sac filled with blood. This is the most common type of aneurysm.

2. False Ventricular Aneurysm or Pseudoaneurysm: This is a little different. What happens here is that the wall of the heart is damaged, and some blood leaks through it and collects in the thin membrane around the heart (the pericardium). This means that the wall of the heart itself does not bulge, but it looks like one.

How common is this situation?

Let's see how common this is. Statistics show that about 5 to 7 out of 100 people who have a heart attack will develop this condition (Ventricular Aneurysm). This risk is even higher if the heart attack has affected the entire thickness of the heart muscle (Transmural Myocardial Infarction).

What are the causes of Ventricular Aneurysm?

As we mentioned earlier, the main and most common cause is a heart attack (`Myocardial Infarction`) . In a heart attack, the blood supply to the heart muscle stops, and those parts die. Then, scar tissue (`Scar Tissue`) forms in those dead areas. Over time, this scar tissue can stretch, thin, and weaken. That's when an ``Aneurysm`` forms.

But very rarely, this condition can be present from birth. That is, as a `Congenital Heart Condition` . If you have one, it may not be known until adulthood, and it can cause problems later.

In addition to this main reason, there are several other very rarely seen reasons:

• Infection of the inner lining of the heart (endocarditis).
• Excessive use of painkillers such as steroids and nonsteroidal anti-inflammatory drugs (NSAIDs) for a long period of time.
• Rheumatic Fever.
• Rare diseases like `(Sarcoidosis)`.
• As a complication of open heart surgery.
• Sexually transmitted diseases like syphilis.
• Traumatic accidents (chest injuries)
• Tuberculosis.
• `(Chagas Disease)` (This is an infection caused by a parasite, which is not very common in Sri Lanka).
• A specific condition of thickening of the heart muscle called ``Apical Hypertrophic Cardiomyopathy''.

Who is at higher risk of developing Ventricular Aneurysm?

Although this condition can develop in anyone, some people are at higher risk. These include:

• Women over 65 years of age.
• If someone in your family has heart disease (`Cardiovascular Disease`), coronary artery disease (`Coronary Artery Disease`), or a history of heart attacks. These are hereditary risk factors.
• People with an enlarged heart (Hypertrophic Cardiomyopathy). In this condition, the heart muscle becomes excessively thick.

What are the symptoms of a `(Ventricular Aneurysm)`?

The amazing thing is that most of the time, if this ``(Ventricular Aneurysm)`` is small, it can be asymptomatic. Some people don't even know they have this, and it is discovered by chance when they are being tested for some other reason.

But some people may experience one or more of these symptoms:

• Chest pain or tightness, a feeling of constriction (`Angina`). This can feel like a heart attack.
• Edema (swelling of the body), especially in the legs and ankles.
• Constant feeling of extreme tiredness (`Fatigue`). Feeling tired even after doing a small task.
• An abnormal, rapid heartbeat, or a feeling of pounding in the chest (`Heart Palpitations`).
• Shortness of Breath. Feeling short of breath even when walking or exerting yourself.
• Stroke. This happens if a blood clot forms inside the aneurysm, breaks away, and blocks a blood vessel in the brain.

What are the possible complications of this `(Ventricular Aneurysm)`?

This is what we need to pay the most attention to. If there is a `(Ventricular Aneurysm)`, it can cause some dangerous complications.

The biggest and most dangerous complication is the rupture of the aneurysm. If that happens, it is life-threatening and an emergency that requires immediate hospitalization and treatment.

Also, very rarely, a condition called ``Cardiogenic Shock'' can occur. Simply put, this is when the heart is unable to pump enough blood to the body. This is also a medical emergency.

Another thing is that this aneurysm weakens the left ventricle of the heart, making it difficult to pump blood to the body. This can lead to heart failure . This means that the heart gradually weakens and is unable to meet the body's needs.

In addition, Ventricular Aneurysm also increases the following risks:

• Blood clots and the resulting strokes.
• Reduced blood flow to the heart muscle (`Myocardial Ischemia`). This can cause increased chest pain.
• A fast, dangerously abnormal heartbeat (`Ventricular Tachycardia`). This can also be life-threatening.

How do doctors diagnose a ventricular aneurysm?

As we mentioned earlier, since they don't always show symptoms, if you've had a heart attack before or have other risk factors for it, your doctor may order various tests to look for this condition. These aneurysms usually begin to form within about three months of a heart attack.

The main imaging tests used to detect these aneurysms are:

• Chest X-rays.
• Angiogram tests. This may include a special scan called a Coronary Computed Tomography Angiogram (CCTA).
• CT scan.
• Echocardiogram (`Echocardiogram`). This is often the first test done, similar to an ultrasound scan of the heart.
• An E.C.G. test (`Electrocardiogram - ECG`). This checks the electrical activity of the heart.
• MRI scan. This can also produce detailed images of the heart.

What are the treatments for this `(Ventricular Aneurysm)`?

Well, now let's see what this can do.

• Small, asymptomatic aneurysms: These may not require major surgery right away. Your doctor will monitor you. They will do the imaging tests mentioned above regularly to see if the aneurysm is changing in size or if there are any signs of problems.
• Lifestyle changes and cardiac rehabilitation: Many people benefit from participating in a program called ``Cardiac Rehabilitation'' after a heart attack. There, specialists help you make heart-healthy lifestyle changes (such as diet and exercise). This can improve heart health and reduce your risk of future heart disease.
• Medications: To reduce the risk of complications, the doctor may prescribe medications such as:
• Aspirin or other medicines that prevent blood clotting (anticoagulants).
• Blood pressure control medication.
• Cholesterol-lowering medications, such as ``Statins``.
• Medications given for heart failure and heart arrhythmia.

Surgery for a True Ventricular Aneurysm

A large, true ventricular aneurysm that causes chest pain, shortness of breath, or heart failure may require surgery. Cardiac surgeons perform an open-heart surgery called ventricular reconstructive surgery or ventricular remodeling .

This surgery involves:

• The weakened, bulging part of the heart muscle (the aneurysm) is removed.
• Then, the healthy parts of the heart are sewn together, or something like a synthetic patch is sewn in to strengthen the weak part.

If you have an irregular heart rhythm (`Arrhythmia`) and cannot control it, you may need to have surgery to implant a small device under the skin of your chest that regulates your heart rate. We call these `(Implantable Cardioverter Defibrillators - ICD)` and `(Pacemakers)` .

Surgery for a ``False Ventricular Aneurysm'' or ``Pseudoaneurysm''

This is a bit of a harsh word, but it's good to know. If left untreated, about half of people who develop these false ventricular aneurysms, or pseudoaneurysms, will die. That's how dangerous they are. Therefore, your doctor will likely recommend open-heart surgery to repair the pseudoaneurysm.

Can the development of this `(Ventricular Aneurysm)` be prevented?

In fact, the best way to prevent a ventricular aneurysm is to try to prevent the main cause, which is heart disease. That means taking care of your heart health. These things will help with that:

• Eat a heart-healthy diet. Eat foods that are low in salt, oil, and sugar, and high in fruits and vegetables.
• Exercise regularly. Even just walking for 30 minutes a day is good.
• Find good ways to manage stress. Things like meditation, yoga, and engaging in a hobby.
• Limit alcohol consumption, and if possible, stop completely.
• If you are overweight, lose weight and maintain a healthy weight.
• If you have conditions that put pressure on your heart, such as high blood pressure, diabetes, or high cholesterol, control them properly. Follow your doctor's instructions and take your medications as directed.
• If you smoke, seek help to quit immediately. It is also very important to avoid secondhand smoke.

What is the outlook for people with this condition?

On average, 9 out of 10 people with a ventricular aneurysm that doesn't cause major problems are still alive five years after diagnosis. That means that if managed properly, you can live a good life.

However, when these aneurysms cause symptoms that are beyond treatment, or when complications occur, the risk of life-threatening problems increases. That is why it is important to get tested and treated as doctors recommend.

When should you see a doctor?

If you experience any of these symptoms, you should call your doctor immediately, or go to the nearest hospital:

• Severe chest pain. As if someone is squeezing your chest, or as if something is weighing you down.
• Severe difficulty breathing.
• Other symptoms of a heart attack (e.g., pain radiating down the left arm, jaw pain, sweating, nausea)
• If you suddenly feel like your heart is beating fast or irregularly.

In such a situation, don't waste time. Call the 1990 (Suvaseriya) ambulance service as soon as possible.

What should you ask the doctor?

If your doctor tells you that you have a ``Ventricular Aneurysm'', it's a good idea to ask a few questions like these. That way, you can get a better understanding of the condition.

• Why did I develop this `(Ventricular Aneurysm)`?
• What type of Ventricular Aneurysm do I have? (Real or False?)
• How big is my aneurysm?
• What should I do to reduce the risk of this aneurysm bursting?
• What kind of medicine will I have to take?
• What are the possible side effects of those medications?
• Will I need surgery?
• If I have surgery, what are the risks?
• What signs of complications should I be concerned about?

Finally, what to remember (Take-Home Message)

So, the ``Ventricular Aneurysm'' we talked about is a bulge that occurs due to a weakening in the wall of one of the lower chambers of the heart. This condition is often seen in people who have had a heart attack. These most commonly occur in the left ventricle.

The important thing is that although it often does not show symptoms, if such symptoms appear (such as chest pain, difficulty breathing), there are medications or surgeries that can be used. However, if a ``Ventricular Aneurysm'' bursts, it can be a very dangerous condition for life.

Therefore, if you experience severe chest pain, difficulty breathing, or other symptoms of a heart attack, do not delay, call 1990 immediately and go to a hospital. It will be a great help in saving your life.

Take care of your heart. Live a healthy lifestyle. Then you can protect yourself from many problems like this.
