Pericardial effusion

To diagnose pericardial effusion, the health care provider will typically perform a physical exam and ask questions about your symptoms and medical history. He or she will likely listen to your heart with a stethoscope. If your health care provider thinks you have pericardial effusion, tests can help identify a cause.

Tests

Tests to diagnose or confirm pericardial effusion may include:

Echocardiogram. Sound waves are used to create pictures of the heart in motion. An echocardiogram shows the heart chambers and how well the heart is pumping blood. The test can help determine the amount of fluid between the two layers of the pericardium. An echocardiogram may also show decreased heart function due to pressure on the heart (tamponade).

Electrocardiogram (ECG or EKG). This quick and painless test measures the electrical activity of the heart. Sticky patches (electrodes) are placed on the chest and sometimes the arms and legs. Wires connect the electrodes to a computer, which displays the test results. Your cardiologist or another health care provider can look for signal patterns that suggest cardiac tamponade.

Chest X-ray. An X-ray image of the chest allows a health care provider to check the size and shape of the heart. A chest X-ray can show signs of an enlarged heart if the effusion is large.

CT and MRI scans can detect pericardial effusion, although they're generally not used to look for the condition. However, pericardial effusion may be diagnosed when these tests are done for other reasons.

Treatment for pericardial effusion depends on:

The amount of fluid buildup

The cause of pericardial effusion

The presence or risk of cardiac tamponade

Medications

If you don't have cardiac tamponade or there's no immediate threat of cardiac tamponade, your health care provider might prescribe one of the following medications to treat inflammation of the pericardium:

Aspirin

Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil, Motrin IB, others)

Colchicine (Colcrys, Mitigare)

A corticosteroid, such as prednisone

Surgery or other procedures

Your health care provider may recommend procedures to drain a pericardial effusion or prevent future fluid buildup if:

Medications don't correct the pericardial effusion

A large effusion is causing symptoms and increasing the risk of cardiac tamponade

You have cardiac tamponade

Drainage procedures or surgery to treat pericardial effusion may include:

Fluid drainage (pericardiocentesis). A health care provider uses a needle to enter the pericardial space and then inserts a small tube (catheter) to drain the fluid. Imaging techniques, typically echocardiography, are used to guide the work. Usually, the catheter is left in place to drain the pericardial space for a few days to help prevent future fluid buildup. The catheter is taken out when all the fluid has drained and isn't re-accumulating.

Open-heart surgery. If there's bleeding into the pericardium, especially due to recent heart surgery or other complicating factors, open-heart surgery may be done to drain the pericardium and repair any damage. Sometimes, a surgeon may create a passageway that allows fluid to drain as needed into the abdominal cavity, where it can be absorbed.

Removal of the pericardium (pericardiectomy). If pericardial effusions continue to occur despite drainage procedures, a surgeon may recommend removing all or part of the pericardium.
