Has your doctor told you to have a 'Heart Biopsy'? Or has anyone you know had this test? It's very normal to feel a little scared and nervous when you hear this name. Who wouldn't be scared when they say "taking a piece of the heart", right? But it's actually not as scary as we think. So let's find out exactly what it is today. We'll talk very simply about what it is, how it's done, and whether there are any risks.
What is a heart biopsy?
Simply put, a heart biopsy is a procedure where a very small piece of tissue is taken from the inner layer of your heart muscle. It's about the size of a pinhead, to be exact. This is a special test. The tissue sample is then examined under a microscope by a pathologist. He or she will look for any damage or abnormalities in the heart cells.
This test is called by several other names. Your doctor may use one of these names:
- Cardiac biopsy
- Endomyocardial biopsy
- Myocardial biopsy
Who wants to do this test?
The main reason for doing a heart biopsy is to monitor the health of someone who has had a heart transplant . Imagine someone who has had a new heart transplant. Sometimes the body tries to reject the new heart. We call this `organ rejection.' So with this biopsy, we can find out if the heart is being rejected before symptoms appear. And we can also identify the cause.
In the early stages after a heart transplant, this test may need to be done once a week. Over time, this may need to be done every six weeks, every three months, for up to a year.
Apart from that, doctors also use this test to diagnose several other medical conditions.
- Cardiomyopathy: This is when the heart muscle becomes weak, enlarged, or thickened, making it difficult to pump blood.
- Myocarditis: An infection or inflammation of the heart muscle.
- Amyloidosis: A condition caused by the deposition of an abnormal protein in the heart.
- Sarcoidosis: The formation of small inflammatory cell masses (granulomas) in various organs of the body, especially the heart and lungs.
- Cardiotoxicity from cancer treatments: See if some anti-cancer drugs (chemotherapy) can harm the heart.
- Heart cancer: These are very rare, but this test is important to detect.
The most important thing is that only your doctor, who knows your medical condition best, can decide whether or not to have this test.
How do you prepare for and take this test?
This is not a major surgery, so there is nothing to be afraid of. This is done by a cardiologist. He uses a technique called cardiac catheterization. This is a test in which a thin tube (catheter) is passed through a blood vessel into the heart.
Things you need to do before the test
Your doctor will advise you clearly about this.
- Tell your doctor about all medications and vitamins you are taking. Especially if you are taking blood thinners, you may be asked to stop taking them a few days before the test.
- You will be asked to abstain from eating or drinking (fasting) for a few hours before the test.
- Ask the doctor about any questions or concerns you may have.
How the test is conducted
The entire procedure takes about an hour. This is an outpatient procedure that can be done at home without having to stay in the hospital.
1. First, you will be given a sedative to relax you and make you feel a little drowsy. Then, the area where the tube will be inserted (usually in the neck or groin) will be numbed. This will prevent you from feeling any pain . You will remain awake throughout the test.
2. The doctor does this by looking at your heart using an X-ray-like technique.
3. A very thin, flexible tube (catheter) is inserted into one of your blood vessels and guided all the way to the right side of your heart.
4. Then, a tiny, forceps-like instrument called a `bioptome` is passed through the tube and about 3 or 5 very small pieces of tissue are taken from the heart muscle.
5. Then, both the device and the tube are removed, and a pressure bandage is applied to the site where the tube was inserted to stop the bleeding.
6. The tissue samples obtained are sent to the laboratory for testing.
You won't feel much pain at this time, but you may feel a little pressure and discomfort.
What happens after the test?
After the test is over, the medical staff will monitor you for a few hours. During this time, a chest X-ray will be taken to check for any complications, such as lung damage (pneumothorax). If everything is fine, you can go home the same day. However, you will need someone to drive you home and it is best if someone is with you that day.
You should avoid lifting weights or doing strenuous work for 24 hours after the test. You can go to work and do your daily activities as usual from the next day.
Are there any risks to this?
A heart biopsy is a relatively safe procedure . But like any medical procedure, there are small risks. Let's be aware of that too.
| Risk type | Simple description |
|---|---|
| Minor and common complications | Bruising, slight bleeding, or pain where the tube was inserted. These usually resolve within a few days. |
| Serious (but very rare) complications | These occur in less than 1% of cases. They can include irregular heartbeat (arrhythmia), damage to a blood vessel, damage to the lungs (pneumothorax), blood clots, or fluid accumulation around the heart (pericardial effusion). However, these are very rare. |
Remember, this test is performed by highly experienced specialists, so the chances of serious complications are very low.
How long does it take for the report to arrive?
The test report is usually available within 24 to 48 hours . That's pretty quick. Your doctor will discuss the report with you and explain what you need to do next.
What time should I call the doctor?
If you experience any of the following symptoms after the test and after going home, notify your doctor immediately or go to the Emergency Department (ETU) of the nearest hospital.
- Dizziness (vertigo)
- Irregular or rapid heartbeat
- Difficulty breathing
- Chest pain (signs of a heart attack)
- Symptoms of a stroke (e.g., weakness on one side of the body, difficulty speaking)
- Fever or chills (signs of infection)
It is very important to be aware of these characteristics.
