Pericardiocentesis is a procedure that uses a needle to remove fluid from the pericardial sac. This is the tissue that surrounds the heart.
How the Test is Performed
The procedure is most often done in a special procedure room, such as a cardiac catheterization laboratory. It may also be done at a patient's hospital bedside. A health care provider will put an IV into your arm in case fluids or medicines need to be given through a vein. For example, you may be given medicines if your heartbeat slows or your blood pressure drops during the procedure.
IV
Intravenous means "within a vein. " Most often it refers to giving medicines or fluids through a needle or tube inserted into a vein. This allows th...
The provider will clean an area just below or next to the breastbone or below the left nipple. Numbing medicine (anesthetic) will be applied to the area.
The doctor will then insert a needle and guide it into tissue that surrounds the heart. Often, echocardiography (ultrasound) is used to help the doctor see the needle and any fluid drainage. An electrocardiogram ( ECG ) and x-rays (fluoroscopy) may also be used to help with positioning.
Echocardiography
An echocardiogram is a test that uses sound waves to create pictures of the heart. The picture and information it produces is more detailed than a s...
ECG
An electrocardiogram (ECG) is a test that records the electrical activity of the heart.
Once the needle has reached the correct area, it is removed and replaced with a tube called a catheter. Fluid drains through this tube into containers. Most of the time, the pericardial catheter is left in place so draining may continue for several hours.
Surgical drainage may be needed if the problem is hard to correct or comes back. This is a more invasive procedure in which the pericardium is drained into the peritoneal (abdominal) or chest (pleural) cavity. This may need to be done when you are under general anesthesia.
How to Prepare for the Test
You may not be able to eat or drink for 6 hours before the test. You must sign a consent form.
How the Test will Feel
You may feel pressure as the needle enters. Some people have chest pain , which may require pain medicine.
Chest pain
Chest pain is discomfort or pain that you feel anywhere along the front of your body between your neck and upper abdomen.
Why the Test is Performed
This test may be done to remove and examine fluid that is pressing on the heart. It is most often done to find the cause of a chronic or recurrent pericardial effusion .
Pericardial effusion
Pericarditis is a condition in which the sac-like covering around the heart (pericardium) becomes inflamed.
It may also be done to treat cardiac tamponade , which is a life-threatening condition.
Cardiac tamponade
Cardiac tamponade is pressure on the heart that occurs when blood or fluid builds up in the space between the heart muscle and the outer covering sac...
Normal Results
There is normally a small amount of clear, straw-colored fluid in the pericardial space.
What Abnormal Results Mean
Abnormal findings may indicate the cause of pericardial fluid accumulation, such as:
-
Cancer
Cancer
Cancer is the uncontrolled growth of abnormal cells in the body. Cancerous cells are also called malignant cells.

Heart, front view - illustration
The external structures of the heart include the ventricles, atria, arteries and veins. Arteries carry blood away from the heart while veins carry blood into the heart. The vessels colored blue indicate the transport of blood with relatively low content of oxygen and high content of carbon dioxide. The vessels colored red indicate the transport of blood with relatively high content of oxygen and low content of carbon dioxide.
