Skilled Treatment for a Heart Emergency
Cardiac
tamponade is an emergency, life-threatening condition in which fluid
accumulates (effusion) rapidly in the pericardium, the membrane surrounding the
heart.
This
fluid quickly compresses the heart, preventing it from adequately pumping blood
because it cannot fill properly.
UT
Southwestern’s skilled heart doctors use a variety of treatments – both
nonsurgical and surgical – to save the lives of people with cardiac tamponade.
They also strive to diagnose and treat the underlying cause of the fluid
accumulation in people who survive.
UT
Southwestern is also home to a dedicated Cardiac Rehabilitation Program. Cardiac rehabilitation is a
critical component of recovery and can prevent future heart disease.
Causes of Cardiac Tamponade
Causes of
cardiac tamponade can include:
- Pericardial effusion: Abnormal buildup of fluid in the
pericardial cavity or between the heart and the pericardium
- Connective tissue disorders
- Drugs
- Infection
- Pericarditis: Inflammation
of the pericardium
- Pneumopericardium:
Air in the pericardial cavity
- Radiation
therapy for
cancer treatment
- Surgery
- Trauma
- Uremia: Presence
of creatinine and urea in the bloodstream
Cardiac Tamponade Symptoms
Cardiac
tamponade can cause symptoms that include:
- Chest pain
(angina)
- Discomfort, sometimes
relieved by sitting up or leaning forward
- High heart rate
(tachycardia)
- High respiratory
rate (tachypnea)
- Low blood
pressure (hypotension)
- Neck vein
distension
- Shortness of
breath (dyspnea)
Diagnosing Cardiac Tamponade
Although
there are no specific diagnostic studies for cardiac tamponade, the doctor might
conduct several tests to detect it. These include:
- Electrocardiography (echo or cardiac ultrasound): To
visualize the heart’s structure and function using a noninvasive imaging test
- Blood pressure check:
To detect pulsus paradoxus, an abnormal decrease in systolic blood
pressure when inhaling
- Cardiac
catheterization: To determine whether left and right atrial
pressures are equal
- Chest X-ray: To look for an
enlarged heart
- Physical exam,
including listening with a stethoscope for distant heart sounds and dullness
with bronchial breathing over the left scapula (Ewart sign)
Treatment for Cardiac Tamponade
Cardiac
tamponade requires hospitalization. Common treatments include:
- Bed rest with
leg elevation: To reduce the heart's workload
- Inotropic drugs,
such as dobutamine: To improve heart function and lower blood pressure
- Volume expansion
with IV fluids: To help maintain the heart's volume
- Oxygen: To
reduce the heart's workload
- Pericardiocentesis:
To drain the fluid from the pericardium using a needle
- Surgery:
- Surgical creation
of a pericardial window to allow drainage of the effusion
- Implantation of
a pericardio-peritoneal shunt to relieve cancer patients whose disease is
causing the fluid accumulation
- Pericardiectomy to remove the
pericardium as a last resort
Support Services
UT
Southwestern’s cardiac
rehabilitation specialists will
create a customized plan that makes nutrition, exercise, and nicotine cessation
programs an integral part of a patient’s daily routine after treatment for
cardiac tamponade.
Clinical
Trials
As one of the nation’s top academic medical centers, UT Southwestern offers a
number of
clinical trials aimed at improving the outcomes of patients with
cardiovascular disease.
Clinical
trials often give patients access to leading-edge treatments that are not yet
widely available. Eligible patients who choose to participate in one of UT
Southwestern’s clinical trials might receive treatments years before they are
available to the public.
