A pericardial effusion is an abnormal accumulation of fluid in the pericardial cavity. The pericardium is a two-part membrane surrounding the heart: the outer fibrous connective membrane and an inner two-layered serous membrane. The two layers of the serous membrane enclose the pericardial cavity (the potential space) between them. [1]
Pericardial fluid. A transverse section of the thorax, showing the contents of the middle and the posterior mediastinum. The pleural and pericardial cavities are exaggerated since normally there is no space between parietal and visceral pleura and between pericardium and heart. Pericardial fluid is the serous fluid secreted by the serous layer ...
The pericardium is a fibrous sac surrounding the heart composed of two layers: an inner visceral pericardium and an outer parietal pericardium. [1] The area between these two layers is known as the pericardial space and normally contains 15 to 50 mL of serous fluid. [2] This fluid protects the heart by serving as a shock absorber and provides ...
Acute pericarditis. An ECG showing pericarditis. Note the ST elevation in multiple leads with slight reciprocal ST depression in aVR. Acute pericarditis is a type of pericarditis (inflammation of the sac surrounding the heart, the pericardium) usually lasting less than 4 to 6 weeks. [1] It is the most common condition affecting the pericardium.
Cardiac tamponade, also known as pericardial tamponade (/ ˌtæm.pəˈneɪd / [ 4 ]), is a compression of the heart due to pericardial effusion (the build-up of pericardial fluid in the sac around the heart). [ 2 ] Onset may be rapid or gradual. [ 2 ] Symptoms typically include those of obstructive shock including shortness of breath, weakness ...
Constrictive pericarditis is defined by a fibrotic (thickened) pericardium. Constrictive pericarditis is a condition characterized by a thickened, fibrotic pericardium, limiting the heart's ability to function normally. [1] In many cases, the condition continues to be difficult to diagnose and therefore benefits from a good understanding of the ...
Pericarditis is inflammation of the pericardium, the fibrous sac surrounding the heart. [ 8 ] Symptoms typically include sudden onset of sharp chest pain, which may also be felt in the shoulders, neck, or back. [ 1 ] The pain is typically less severe when sitting up and more severe when lying down or breathing deeply. [ 1 ]
ICD-9-CM. 37.31. MeSH. D010492. [edit on Wikidata] Pericardiectomy is the surgical removal of part or most of the pericardium. [1][2] This operation is most commonly used to relieve constrictive pericarditis, or to remove a pericardium that is calcified and fibrous. [2] It may also be used for severe or recurrent cases of pericardial effusion. [3]
