Cardiac tamponade
Tamponade; Pericardial tamponade; Pericarditis - 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 of the heart.
Causes
In this condition, blood or fluid collects in the sac surrounding the heart. This prevents the heart ventricles from expanding fully. The excess pressure from the fluid prevents the heart from working properly. As a result, the body does not get enough blood.
Cardiac tamponade can occur due to:

- Rapid breathing
- Heart rate over 100 (normal is 60 to 100 beats per minute)
- Heart sounds are only faintly heard through a stethoscope
- Neck veins that may be bulging (distended) but the blood pressure is low

Treatment
Cardiac tamponade is an emergency condition that needs to be treated in the hospital.
The fluid around the heart must be drained as quickly as possible. A procedure that uses a needle to remove fluid from the tissue that surrounds the heart will be done.

Pericardiocentesis is a procedure that uses a needle to remove fluid from the pericardial sac. This is the tissue that surrounds the heart.
A surgical procedure to cut and remove part of the covering of the heart (pericardium) may also be done. This is known as surgical pericardiectomy or pericardial window.
Fluids are given to keep blood pressure normal until the fluid can be drained from around the heart. Medicines that increase blood pressure may also help keep the person alive until the fluid is drained.
Oxygen may be given to help reduce the workload on the heart by decreasing tissue demands for blood flow.
The cause of tamponade must be found and treated.
Outlook (Prognosis)
Death due to cardiac tamponade can occur quickly if the fluid or blood is not removed promptly from the pericardium.
The outcome is often good if the condition is treated promptly. However, tamponade may come back.
Possible Complications
Complications may include:
-
Heart failure
Heart failure
Heart failure is a condition in which the heart is no longer able to pump oxygen-rich blood to the rest of the body efficiently. This causes symptom...

When to Contact a Medical Professional
Go to the emergency room or call the local emergency number (such as 911) if symptoms develop. Cardiac tamponade is an emergency condition that needs immediate medical attention.
Prevention
Many cases can't be prevented. Knowing your personal risk factors may help you get early diagnosis and treatment.

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.

Cardiac tamponade - illustration
Cardiac tamponade is a condition involving compression of the heart caused by blood or fluid accumulation in the space between the myocardium (the muscle of the heart) and the pericardium (the outer covering sac of the heart). Blood or fluid collects within the pericardium. This prevents the ventricles from expanding fully, so they cannot adequately fill or pump blood. Cardiac tamponade is an emergency condition that requires hospitalization.
