constrictive pericarditis

pericarditis /peri·car·di·tis/ (-kahr-di´tis) inflammation of the pericardium.pericardit´ic

---

adhesive pericarditis  a condition due to the presence of dense fibrous tissue between the parietal and visceral layers of the pericardium.

constrictive pericarditis  a chronic form in which a fibrotic, thickened, adherent pericardium restricts diastolic filling and cardiac output, usually resulting from a series of events beginning with fibrin deposition on the pericardial surface followed by fibrotic thickening and scarring and obliteration of the pericardial space.

fibrinous pericarditis , fibrous pericarditis that characterized by a fibrinous exudate, sometimes accompanied by a serous effusion; usually manifested as a pericardial friction rub.

pericarditis obli´terans , obliterating pericarditis adhesive pericarditis that leads to obliteration of the pericardial cavity.

con·stric·tive pericarditis (kn-strktv)

n.

Tuberculous or other infection of the pericardium, with thickening of the membrane and constriction of the cardiac chambers.

constrictive pericarditis,

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.

pericarditis

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.

constrictive pericarditis

adhesions between the epicardium and pericardium limit the movement of the heart sometimes sufficiently to cause congestive heart failure.

niche pericarditis

see niche pericarditis.

traumatic 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.
