The pericardium is a fibroelastic sac made up of visceral and parietal layers separated by a (potential) space, the pericardial cavity. In healthy individuals, the pericardial cavity contains 15 to 50 mL of an ultrafiltrate of plasma.
Diseases of the pericardium present clinically in one of four ways:
●Acute and recurrent pericarditis
●Pericardial effusion without major hemodynamic compromise
