Chronic pericarditis

After acute pericarditis, scar adhesions and calcium deposits can be left on the pericardium. Most patients have only slight scarring and loose or local adhesions. The pericardium does not significantly thicken and does not affect the function of the heart. It is called chronic adhesive pericarditis and is not clinically important. Pericardial exudate persists in some patients for a long time, forming chronic effusive pericarditis, which may be a chronic process of acute non-specific pericarditis. It is mainly manifested as pericardial effusion and has a good prognosis. A few patients have formed thick scar Tissue and pericardium lose flexibility, which significantly affects the systolic and diastolic function of the heart. It is called constrictive pericarditis. It includes the typical chronic constrictive pericarditis and the pericardium that has occurred while the pericardium exudates Constricted subacute effusive constrictive pericarditis, the latter clinically shows both pericardial obstruction and pericardial constriction, and eventually evolves into a typical chronic constrictive pericarditis.
