The pericardium, the double-walled sac surrounding the heart, consists of a fibrous pericardium layer on the outside and a double-layered serous pericardium on the inside. [18] Between the two layers of the serous pericardium is the pericardial space, which is filled with lubricating serous fluid that prevents friction as the heart contracts. [19]
Pericardiocentesis can be used to diagnose and treat cardiac tamponade. [3] [4] Cardiac tamponade is a medical emergency in which excessive accumulation of fluid within the pericardium (pericardial effusion) creates increased pressure. [5] This prevents the heart from filling normally with blood.
Beck's triad is a collection of three medical signs associated with acute cardiac tamponade, a medical emergency when excessive fluid accumulates in the pericardial sac around the heart and impairs its ability to pump blood. The signs are low arterial blood pressure, distended neck veins, and distant, muffled heart sounds. [1]
A very large hemorrhagic pericardial effusion due to malignancy as seen on ultrasound which was causing tamponade. closed arrow: the heart, open arrow: the effusion. Tamponade (/ ˌ t æ m. p ə ˈ n eɪ d / [1]) is the closure or blockage (as of a wound or body cavity) by or as if by a tampon, especially to stop bleeding. [2]
Purulent Pericarditis; Echocardiogram showing pericardial effusion with signs of cardiac tamponade: Specialty: Cardiology: Symptoms: substernal chest pain (exacerbated supine and with breathing deeply), dyspnea, fever, rigors/chills, and cardiorespiratory signs (i.e., tachycardia, friction rub, pulsus paradoxus, pericardial effusion, cardiac tamponade, pleural effusion)
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 ).
This procedure typically utilizes an 8-cm, 18-gauge needle that is inserted between the xiphoid process and the left costal margin until it enters the pericardial sac, when it can then be used to drain the fluid from the sac. [6] A catheter is often left in the pericardium to continue draining any remaining fluid after the initial procedure. [7]
In cardiac tamponade, blood or other fluids building up in the pericardium can put pressure on the heart so that it is not able to beat. This condition can be recognized by the presence of a narrowing pulse pressure , muffled heart sounds , distended neck veins, electrical alternans on the electrocardiogram , or by visualization on echocardiogram .
