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]
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 ...
Hemopericardium is a condition that affects the cardiovascular system. It typically begins with blood accumulating in the pericardial sac posterior to the heart, and eventually expands to surround the entire heart. [6] The fluid build-up then causes pressure within the pericardial sac to increase. If the pressure becomes greater than the ...
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 ...
Here it can cause right-sided heart failure, arrhythmias, pericardial effusion, and cardiac tamponade. Hemangiosarcoma of the spleen or liver is the most common tumor to cause hemorrhage in the abdomen. [4] Hemorrhage secondary to splenic and hepatic tumors can also cause ventricular arrythmias.
Erdheim–Chester disease. Erdheim–Chester disease (ECD) is an extremely rare disease characterized by the abnormal multiplication of a specific type of white blood cells called histiocytes, or tissue macrophages (technically, this disease is termed a non- Langerhans-cell histiocytosis). It was declared a histiocytic neoplasm by the World ...
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.
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 ...
