In contrast to other causes of pericarditis which may have a viral etiology, purulent pericarditis refers specifically to bacterial or fungal infection of the pericardial sac. [2] Clinical etiologies of purulent pericarditis may include recent surgery, adjacent infection, trauma, or even primary infection . [ 3 ]
The pericardial rub is said to be generated from the friction generated by the two inflamed layers of the pericardium; however, even a large pericardial effusion does not necessarily present a rub. The rub is best heard during the maximal movement of the heart within the pericardial sac, namely, during atrial systole , ventricular systole, and ...
A pericardial effusion with enough pressure to adversely affect heart function is called cardiac tamponade. [1] Pericardial effusions can cause cardiac tamponade in acute settings with fluid as little as 150mL. In chronic settings, however, fluid can accumulate anywhere up to 2L before an effusion causes cardiac tamponade.
Pericarditis may be caused by viral, bacterial, or fungal infection. In the developing world the bacterial disease tuberculosis is a common cause, whereas in the developed world viruses are believed to be the cause of about 85% of cases. [6] Viral causes include coxsackievirus, herpesvirus, mumps virus, and HIV among others. [4]
Cardiac tamponade, also known as pericardial tamponade (/ ˌ t æ m. p ə ˈ n eɪ d / [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]
The cause of constrictive pericarditis in the developing world are idiopathic in origin, though likely infectious in nature. In regions where tuberculosis is common, it is the cause in a large portion of cases. [3] Causes of constrictive pericarditis include: Tuberculosis [4] Incomplete drainage of purulent pericarditis [4] Fungal and parasitic ...
The disease consists of persistent low-grade fever, chest pain (usually pleuritic), pericarditis (usually evidenced by a pericardial friction rub, chest pain worsening when recumbent, and diffuse ST elevation with PR segment depression), and/or pericardial effusion. The symptoms tend to occur 2–3 weeks after myocardial infarction but can also ...
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 ...
