postinflammatory thickening and scarring of the membrane producing constriction of the cardiac chambers; may be acute, subacute, or chronic. Formerly called chronic constrictive pericarditis.
Fibrous thickening of the pericardium that restricts diastolic filling of the heart, often resulting from infection, surgery, or radiation.
a fibrous thickening of the pericardium caused by gradual scarring or fibrosis. The pericardium may undergo calcification and gradually becomes rigid, resisting the normal dilation of the heart chambers during the blood-filling phases of the cardiac cycle.
constrictive pericarditisCardiology A condition characterized by a chronic inflammation, fibrosis and scarring of a pericardium contracted to the point of compromising normal diastolic filling of the ventricles Etiology Infection, connective tissue disease, malignancy, trauma, metabolic disorders–eg uremia, RT, sarcoidosis, asbestosis, previous MI, TB, viral infection, cardiac surgery Clinical Right-sided CHF, ↓ cardiac output Complications Cardiac tamponade, pulmonary edema Management Surgical incision. See Pericardium.
con·stric·tive per·i·car·di·tis(kŏn-strik'tiv per'i-kahr-dī'tis)
Postinflammatory thickening and scarring of the membrane producing constriction of the cardiac chambers; may be acute, subacute, or chronic. Formerly called chronic constrictive pericarditis.
constrictive pericarditisInflammation and thickening by fibrous tissue of the outer covering of the heart (pericardium) that prevents normal relaxation and filling of the heart chambers. Also known as Pick's disease (F.J. Pick, 1867–1926, German physician).
inflammation of the pericardium. Initially there is an audible friction rub on auscultation. Later as fluid accumulates there is a muffling of the heart sounds and sometimes a washing machine sound on auscultation. Congestive heart failure develops terminally. Classified according to exudate produced as fibrinous, fibrinohemorrhagic, hemorrhagic, purulent.
adhesions between the epicardium and pericardium limit the movement of the heart sometimes sufficiently to cause congestive heart failure.
see niche pericarditis.
occurs in cattle and goats, rarely sheep, when a sharp foreign body is swallowed and lodges in the reticulum, subsequently perforating its wall. The perforation may go as far forward as the pericardial sac, especially if the animal is pregnant. The animal dies of a combination of congestive heart failure and toxemia due to the bacterial infection.
