What is the pathophysiology of pericarditis?

Pathophysiology of Pericarditis Acute pericarditis develops quickly, causing inflammation of the pericardial sac and often a pericardial effusion. Inflammation can extend to the epicardial myocardium (myopericarditis). Adverse hemodynamic effects and rhythm disturbance are rare, although cardiac tamponade is possible.

What is fibrosis pericarditis?

Constrictive pericarditis occurs when a thickened fibrotic pericardium, of whatever cause, impedes normal diastolic filling. This usually involves the parietal pericardium, although it can involve the visceral pericardium (see Constrictive-Effusive Pericarditis).

What myocardial infarction fibrinous pericarditis can occur?

Post-Myocardial Infarction Pericarditis, also named peri-infarction pericarditis, is defined as acute pericarditis occurring within 7 days following an acute myocardial infarction.

Why is it called bread and butter pericarditis?

The image presented herein refers to a typical fibrinous pericarditis, also known as “bread and butter” pericarditis. In such an entity, the pericardium, which is regularly smooth and bright, becomes opaque and granular, and macroscopically resembles two pieces of buttered bread pressed together then pulled apart.

What are the classifications of pericarditis?

The main types of pericarditis include viral and bacterial pericarditis, constrictive pericarditis, post-heart attack pericarditis, chronic effusive pericarditis and pericarditis following heart surgery.

What causes heart constriction?

Viral infections leading to inflammation of the pericardium are one of the more common causes of pericardial constriction. It can also develop as a side effect of radiation therapy or heart surgery. Less common causes include connective tissue diseases, cancer, and complications from other types of infections.

What is the difference between fibrous and serous pericardium?

Fibrous pericardium is the outer layer. It’s made from thick connective tissue and is attached to your diaphragm. It holds your heart in place in the chest cavity and protects from infections. Serous pericardium is the inner layer.

What is the function of fibrous pericardium?

Fibrous pericardium is the outer layer. It’s made from thick connective tissue and is attached to your diaphragm. It holds your heart in place in the chest cavity and protects from infections.

What is the difference between pericarditis and cardiac tamponade?

Pericarditis can be divided into non-constructive and constrictive pericarditis. Pericarditis is commonly associated with pericardial effusion that can sometimes worsen to cardiac tamponade. Cardiac tamponade is a grave condition that happens after sudden and/or excessive accumulation of fluid in the pericardial space.

What is tamponade physiology?

• Cardiac tamponade is a life-threatening, slow or rapid compression of the heart due. to the pericardial accumulation of fluid, pus, blood, clots or gas as a result of inflammation, trauma, rupture of the heart or aortic dissection.
