Pericardial effusion is a common clinical condition and is one of the manifestations of an unhealthy pericardium. Pericarditis, trauma, infective endocarditis, tumors, and cardiac insufficiency can all cause pericardial effusion. Pericardial effusion can be cured, but first of all, the primary cause of pericardial effusion must be cured, such as tuberculosis and bacterial infection, and the viral infection as well as bacterial and tuberculosis infection must be controlled, so that the pericardial effusion will not return after it is pumped. In addition, if it is caused by heart trauma or rupture of large blood vessels, heart or large blood vessel repair surgery can be performed in order to achieve the purpose of the eradication of pericardial effusion.
