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)
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
Pericardial effusions can be found in all populations worldwide but the predominant etiology has changed over time, varying depending on the age, location, and comorbidities of the population in question. [2] Out of all the numerous causes of pericardial effusion, some of the leading causes are inflammatory, infectious, neoplastic and traumatic.
Whether an effusion causes tamponade depends on the amount of fluid and how long it took to accumulate. When fluid collects slowly, the pericardium can stretch. Thus, a chronic effusion can be as large as 1 liter. [20] Acute effusions can cause tamponade when small because the tissue does not have time to stretch. [21]
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]
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]
A pericardial effusion is the presence of excessive pericardial fluid, this can be confirmed using an echocardiogram. [7] Small effusions are not necessarily dangerous and are commonly caused by infection such as HIV or can occur after cardiac surgery.
On auscultation, pericardial friction rub can be heard. Cardiac tamponade: Cardiac tamponade occurs due to fluid accumulation in the pericardial space and typically presents with chest pain often accompanied by symptoms like dyspnea, hypotension, and pulsus paradoxus. Clinical signs include Beck's triad—hypotension, jugular venous distension ...
