This pericardial space contains a small amount of pericardial fluid, normally 15-50 mL in volume. [2] The pericardium, specifically the pericardial fluid provides lubrication, maintains the anatomic position of the heart in the chest ( levocardia ), and also serves as a barrier to protect the heart from infection and inflammation in adjacent ...
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 of the pericardium into the pericardial cavity. The pericardium consists of two layers, an outer fibrous layer and the ...
Pericardiocentesis (PCC), also called pericardial tap, is a medical procedure where fluid is aspirated from the pericardium (the sac enveloping the heart). Anatomy and physiology [ edit ]
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).
On a chest X-ray, the normal heart silhouette should have a clear and defined outline. However, in cases of pericardial effusion, the accumulation of fluid within the pericardial sac causes the heart to appear enlarged and assumes a shape that is reminiscent of a water bottle, with relatively smooth cardiac contours.

Serous membrane fluid collects on microvilli on the outer layer and acts as a lubricant and reduces friction from muscle movement. This can be seen in the lungs, with the pleural cavity. Pericardial fluid is a serous fluid secreted by the serous layer of the pericardium into the pericardial cavity. The pericardium consists of two layers, an ...
Though it only contains a small amount of fluid normally, it can sometimes accumulate fluid or air that widens the space. [2] The pericardial space is another potential space that may fill with fluid (effusion) in certain disease states (e.g. pericarditis; a large pericardial effusion may result in cardiac tamponade).
Pericardiocentesis is a procedure whereby the fluid in a pericardial effusion is removed through a needle. It is performed under the following conditions: [15] presence of moderate or severe cardiac tamponade; diagnostic purpose for suspected purulent, tuberculosis, or neoplastic pericarditis; persistent symptomatic pericardial effusion
