Cardiac tamponade is compression of the heart that occurs when blood or fluid builds up in the space between the myocardium (heart muscle) and the pericardium (outer covering sac of the heart).
Tamponade; Pericardial tamponade
Causes, incidence, and risk factors
In this condition, blood or fluid collects in the pericardium. This prevents the ventricles from expanding fully. The excess pressure from the fluid prevents the heart from functioning normally.
Cardiac tamponade can occur due to:
Dissecting aortic aneurysm(thoracic)
- End-stage lung cancer
- Heart attack (
- Heart surgery
Pericarditiscaused by bacterial or viral infections
- Wounds to the heart
Other potential causes include:
- Heart tumors
Hypothyroidism Kidney failure
- Placement of central lines
Radiation therapyto the chest
- Recent invasive heart procedures
- Recent open heart surgery
Systemic lupus erythematosus
Cardiac tamponade occurs in approximately 2 out of 10,000 people.
