OverviewWhat is cardiac tamponade?Cardiac tamponade happens when the fluid sac around your heart fills with blood or other fluid, putting pressure on your heart. Because of the pressure, your heart can’t fill up with blood, reducing how much blood your heart can pump and ultimately causing a drop in blood pressure. Trauma and certain diseases can cause cardiac tamponade. If not treated, it is always fatal. Show
What happens in cardiac tamponade?Inside your chest, your heart is contained within a sac called the pericardium. The pericardium has two layers and holds your heart in place, and it also contains pericardial fluid. The fluid helps cushion your heart from outside force and stress. The chambers of your heart have to expand to fill up with blood before pumping blood out. Cardiac tamponade — which is sometimes called pericardial tamponade — happens when the pericardium fills with fluid (especially blood). Because the fluid has nowhere to go, your heart runs out of room and can’t expand enough to fill effectively. What’s the difference between pericardial effusion and cardiac tamponade?Pericardial effusion is the technical term for when the pericardium is filling up with fluid. Cardiac tamponade is when pressure from surrounding fluid keeps your heart from beating. Effusions can consist of blood, discharge and other blood components products. Cardiac tamponade may not happen or will take longer to happen when the pericardium fills up with fluid slowly. This is because it has time to stretch and make more room for fluid, and the process may not cause symptoms. However, cardiac tamponade can still happen even when it takes days, weeks or months for enough fluid to accumulate. Symptoms and CausesWhat causes fluid to surround and compress my heart?Several different types of injuries can cause cardiac tamponade. For example, it can happen with blunt trauma, such as a fall or a car crash, or penetrating trauma, like a stab wound from a knife. It can also happen as a result of another injury, such as an aortic dissection. This happens when a tear forms in the wall of the aorta, a major artery in the center of your body. Blood can accumulate in between layers of the aorta’s walls and cause the artery to rupture, filling the pericardium with blood. Cardiac tamponade is also caused by or linked to several diseases and conditions. These include:
In some cases, cardiac tamponade can also happen after a medical procedure. Some of these include:
What are the symptoms of cardiac tamponade?Cardiac tamponade that happens quickly can cause the following symptoms:
Cardiac tamponade that happens more slowly may also cause these symptoms:
Who does cardiac tamponade affect?This condition can happen to people of all ages. Cardiac tamponade caused by other diseases happens to about two out of every 10,000 people. How does compression of the heart affect my body?Cardiac tamponade is dangerous because it ultimately limits the cardiac output, which is the amount of blood your heart can pump. This deprives your body of blood and oxygen. Eventually, it can cause your heart to stop entirely, a potentially fatal condition called cardiac arrest. Diagnosis and TestsHow is cardiac tamponade diagnosed?Several different tests and methods can help diagnose cardiac tamponade. However, certain tests are more likely to be used when it happens quickly because they can deliver a fast diagnosis. Healthcare providers are most likely to diagnose cardiac tamponade using the following:
A hallmark sign of cardiac tamponade is a trio of symptoms known as Beck’s triad:
However, Beck’s triad doesn’t always happen when a person has cardiac tamponade, so a lack of these isn’t a guarantee it isn’t happening. Management and TreatmentHow can this condition be treated?Treating cardiac tamponade requires removing the fluid from around the heart. It may also call for repairing damage (which may have caused or was caused by the fluid buildup). Treatments used include:
Depending on what caused your cardiac tamponade and how it was treated, you may be given pain medications, antibiotics or other medications. What complications are possible with cardiac tamponade?Cardiac tamponade complications can include:
Pericardiocentesis and surgery can have the following complications:
PreventionCan cardiac tamponade be prevented?Because either diseases or injuries can cause it, cardiac tamponade is extremely difficult to predict and prevent. However, it may be possible to avoid it with early detection and treatment of a pericardial effusion, especially after an injury or with conditions that you know you have. Outlook / PrognosisHow long does it take to recover?Your healthcare provider can give you guidance on what you should and shouldn’t do while you’re recovering from cardiac tamponade and any procedure used to treat it. If you had surgery, it’s likely that your provider will tell you to avoid physical activity during the healing process. If a disease is what caused your cardiac tamponade, how you manage it will change depending on your situation. Your provider can guide you on what you can and should do once you go home. When should I go to the emergency room?Cardiac tamponade is a medical emergency and needs immediate care. If you have any injury to your chest, especially near your heart, you should seek urgent medical attention. This includes injuries from any impact (where your skin isn't broken) or that penetrate your skin. You should also seek urgent medical attention if you’re recovering from cardiac tamponade and any of the symptoms return. You should also go to the hospital if you had surgery or pericardiocentesis and you show any symptoms of an infection. These include:
Cardiac tamponade is a serious medical condition, and it is normal to feel fear or anxiety if you or a loved one have been diagnosed with it. Caring for your mental health can be an important part of recovery for you or your loved one. Your healthcare provider can connect you with resources, including counseling or other mental health services, which can help you cope. What is the pericardiocentesis position?Position. The patient undergoing pericardiocentesis is positioned supine with the head of the bed raised between a 30 and 60 degree angle. This places the heart in proximity to the chest wall for easier insertion of the needle into the pericardial sac.
What is the best way to treat cardiac tamponade?How is cardiac tamponade treated? Cardiac tamponade is often a medical emergency and quick removal of the pericardial fluid is needed. The most common procedure to do so is called a pericardiocentesis. A needle and a long thin tube (a catheter) are used to remove the fluid.
How do you set up pericardiocentesis?During pericardiocentesis, a doctor inserts a needle through the chest wall and into the tissue around the heart. Once the needle is inside the pericardium, the doctor inserts a long, thin tube called a catheter. The doctor uses the catheter to drain excess fluid. The catheter may come right out after the procedure.
What is the best location to place a needle into the chest to perform pericardiocentesis?The needle insertion site is in the fifth left intercostal space close to the sternal margin. Advance the needle perpendicular to the skin (at the level of the cardiac notch of the left lung).
