Surgical removal of the pericardium, pericardiectomy, may be used in severe cases and where the pericarditis is causing constriction, impairing cardiac function. It is less effective if the pericarditis is a consequence of trauma, in elderly patients, and if the procedure is done incompletely.
Pericarditis: Here the pericardium gets inflamed. Acutely, it can cause pericardial effusion leading to cardiac tamponade and death. After healing, there may be fibrosis and adhesion of the pericardium with the heart leading to constriction of the heart and reduced cardiac function. Myocarditis: Here the muscle bulk of the heart gets inflamed ...
Fibrinous pericarditis is an exudative inflammation. The pericardium is infiltrated by the fibrinous exudate. This consists of fibrin strands and leukocytes. Fibrin describes an amorphous, eosinophilic (pink) network.
Electrocardiogram (ECG) changes in acute pericarditis mainly indicates inflammation of the epicardium (the layer directly surrounding the heart), since the fibrous pericardium is electrically inert. For example, in uremia, there is no inflammation in the epicardium, only fibrin deposition, and therefore the EKG in uremic pericarditis will be ...
Myopericarditis is a combination of both myocarditis and pericarditis appearing in a single individual, namely inflammation of both the pericardium and the heart muscle. It can involve the presence of fluid in the heart .
In the days following an infarction, the tissue around the infarcted area becomes inflamed and is invaded by neutrophils, which can lead to pericarditis, inflammation of the pericardium. In the next couple weeks, macrophages invade the tissue, and the healing process begins with the formation of granulation tissue, which is new connective ...
A major complication during this period is fibrinous pericarditis, particularly in transmural ventricular wall damage (an infarct that impacted all 3 layers of the heart, the epicardium, myocardium, and endocardium). This leads to inflammation, such as swelling, leading to rubbing of the heart on the pericardium.
The pericardium (pl.: pericardia), also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. [1] It has two layers, an outer layer made of strong inelastic connective tissue ( fibrous pericardium ), and an inner layer made of serous membrane ( serous pericardium ).
