What kind of doctor treats Cardiac Tamponade?
Cardiac tamponade is treated in the hospital by emergency doctors and a cardiologist, a doctor who treats heart problems. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is cardiac tamponade?
Cardiac tamponade is pressure on the heart. It happens when blood or fluid builds up in the space between the heart muscle and the pericardium, the outer covering sac of the heart. The pressure keeps the heart chambers from filling fully, so the heart cannot pump well and the body does not get enough blood. It is an emergency that needs hospital treatment. Cardiac tamponade due to disease occurs in about 2 out of 10,000 people.
Symptoms
Signs may include:
- Sharp chest pain felt in the neck, shoulder, back, or abdomen.
- Chest pain that gets worse with deep breathing or coughing.
- Discomfort that is sometimes relieved by sitting upright or leaning forward.
- Breathing problems and rapid breathing.
- Fainting or dizziness.
- Anxiety and restlessness.
- Pale, gray, or blue skin.
- Palpitations, a pounding or fast heartbeat.
- Swelling of the legs or abdomen.
- Weak or absent pulse.
Causes and who gets it
Blood or fluid collects in the sac around the heart. Causes include:
- A dissecting aortic aneurysm, a tear in the wall of the body's main artery.
- A heart attack.
- Heart surgery or recent invasive heart procedures.
- Pericarditis, inflammation of the sac, caused by bacterial or viral infections.
- Wounds to the heart.
- End-stage lung cancer and other cancers, such as leukemia.
- Heart tumors, heart failure, kidney failure, an underactive thyroid, lupus, placement of central lines, and radiation to the chest.
How doctors diagnose it
An echocardiogram, a test that uses sound waves to picture the heart, is the test of choice. It can be done at the bedside in emergencies. A physical exam may show blood pressure that falls with deep breathing, rapid breathing, faint heart sounds, and bulging neck veins with low blood pressure. Other tests may include an ECG, a chest x-ray, chest CT or MRI, coronary angiography, and right heart catheterization.
Treatment
The fluid around the heart must be drained as quickly as possible. The main treatment is pericardiocentesis, a procedure that uses a needle to remove fluid from the sac around the heart. Echocardiography helps guide the needle. A catheter, a small flexible tube, may stay in place so draining can continue for several hours.
A surgical procedure to cut and remove part of the covering of the heart may also be done. This is known as a surgical pericardiectomy or pericardial window. Until the fluid is drained, fluids and medicines that raise blood pressure help keep the person alive, and oxygen may be given to reduce the workload on the heart. The cause of the tamponade must also be found and treated.
When to see a doctor
Go to the emergency room or call 911 if you have signs of cardiac tamponade, such as sharp chest pain, trouble breathing, fainting, or pale or blue skin. Death can occur quickly if the fluid is not removed promptly, so this condition needs immediate medical attention.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Such a doctor can spot warning signs early, refer you to a cardiologist, and follow your recovery after treatment. They can also help manage conditions that raise the risk of fluid buildup, such as kidney or thyroid problems.
Common questions
Is cardiac tamponade an emergency?
Yes. It needs immediate medical attention in a hospital. Death can occur quickly if the fluid or blood around the heart is not removed promptly.
Can cardiac tamponade come back?
Yes. The outcome is often good if the condition is treated promptly, but tamponade may come back. That is why the underlying cause must be found and treated.
What are the risks of pericardiocentesis?
Risks may include bleeding, a collapsed lung, heart attack, infection, irregular heartbeats, and puncture of the heart, lung, liver, or stomach.
Can cardiac tamponade be prevented?
Many cases cannot be prevented. Knowing your personal risk factors may help you get early diagnosis and treatment.
