Definition of pericardium in English:



  • The membrane enclosing the heart, consisting of an outer fibrous layer and an inner double layer of serous membrane.

    • ‘Reference to the pericardium, epicardium, myocardium, endocardium and valves, chordae, ventricular thicknesses, and aorta and major vessels may be included.’
    • ‘With this patient, the images of the communication between the pericardium and the thoracic duct could be more clearly identified, due to improvements in computerizing techniques.’
    • ‘The pericardial stage was used to suspend the pericardium and the phrenic nerve was preserved throughout its course.’
    • ‘Typically metastatic melanoma involves the pericardium and myocardium; only rarely does it involve the endocardium or cardiac valves.’
    • ‘One patient demonstrated multiple recurrences on the chest wall, with eventual direct extension to the pericardium, pleura, and lung.’


Late Middle English modern Latin, from Greek perikardion, from peri ‘around’ + kardia ‘heart’.
