==Overview==
*Present as part of a generalized disease
Pericarditis is [[inflammation]] of the [[pericardium]], which is the double-walled sac that contains the [[heart]] and the roots of the [[great vessels]]. There can be an accompanying accumulation of [[fluid]] that can be either [[serous]] (free flowing [[fluid]]) or [[fibrinous]] (an [[exudate]], which is a thick [[fluid]] composed of [[proteins]], [[fibrin]] strands, [[inflammatory cells]], [[cell]] breakdown products, and sometimes [[bacteria]]). [[Vascular congestion]] of the [[pericardium]] is also present. The underlying [[myocardium]] may or may not be [[inflamed]] as well. If the [[myocardium]] is involved in the [[inflammatory process]], it is called [[myopericarditis]], and [[CK]] and [[troponin]] levels may be elevated. [[Cardio|Cardiotropic]] [[viruses]] usually spread to the [[myocardium]] and [[pericardium]] [[Hematogen|hematogenously]] and cause [[acute]] [[inflammation]] with [[Infiltration (medical)|infiltration]] of [[Polymorphonuclear cells|polymorphonuclear]] ([[PMN]]) [[leukocytes]] and [[pericardial]] vascularization. Most [[patients]] with [[viral]] pericarditis recover completely with few developing recurrences. Some [[patients]] develop [[constrictive pericarditis]] which could be disabling. [[Bacterial]] pericarditis results from [[contiguous]] spread of [[infection]] within the [[chest]], either [[de novo]] or after [[surgery]] or [[trauma]], spread from [[infective endocarditis]], [[Hematogen|hematogenous]], or direct [[inoculation]] as a result of [[Penetrating trauma|penetrating injury]] or [[cardiothoracic surgery]].
*Present as an isolated disease
*Present as part of a disease that affects nearby organs
*Present as part of multiple diseases

==Pathophysiology==
===Anatomy and Physiology of Pericardium===
 
====Layers of the Pericardium====
*The [[pericardium]] is made up of two layers:<ref =="" “kishore”="">Kishore, K. (2003). The Heart of Structural Development: The Functional Basis of the Location and Morphology of the Human Vascular Pump. J Postgrad Med, 49:282-4.</ref><ref =="" "moore"="">Moore, K. L., Agur, A.

Lippincott Williams & Wilkins.</ref>
**[[Fibrous]] [[pericardium]]:
***Hard protective external layer
***Attached to [[sternum]] anteriorly by [[Sternum|sterno]]-[[pericardial]] [[ligaments]] and fused with the [[central tendon]] of the [[diaphragm]] and [[great vessels]] to allow [[mobility]] of the [[pericardial sac]] against sudden [[cardiac]] overfilling
**[[Serous pericardium]]:
***Smooth [[internal]] layer made up of 2 components:
****[[Parietal]]: reflects onto [[fibrous pericardium]]
****[[Visceral]]: reflects onto [[heart]] and [[great vessels]] and forms the [[epicardium]], the external layer of the [[heart]] wall
*[[Pericardial cavity]]: Potential space between [[parietal]] and [[visceral]] layers. It contains a [[serous fluid]] film that occupies the [[cavity]] and functions as [[lubricant]] against [[friction]] by all [[chest]] movements.
 
====Pericardial Sinuses====
 
*There are two small chambers or [[Sinuse|sinuses]] located where the [[visceral]] and [[parietal]] [[pericardium]] are [[continuous]] with one another within the [[pericardial cavity]].<ref =="" “kishore”="">Kishore, K. (2003). The Heart of Structural Development: The Functional Basis of the Location and Morphology of the Human Vascular Pump. J Postgrad Med, 49:282-4.</ref><ref =="" "moore"="">Moore, K. L., Agur, A. M., & Dalley, A. F. (2011). Essential Clinical Anatomy - Fourth Edition. Lippincott Williams & Wilkins.</ref><ref =="" "tank"="">Tank, P. W. (2009). Grant's Dissector - Fourteenth Edition. Lippincott Williams & Wilkins.</ref>
*[[Transverse sinus]]:
**Located [[posterior]] to the [[pulmonary trunk]] and [[ascending aorta]] at the level between the [[superior vena cava]] and [[aortic arch]]
**Formed after [[dorsal]] [[myocardium]] ruptured [[Embryonic|embryonically]]
**Functional role is to allow the unhindered expansion of [[great arteries]] [[Posterior|posteriorly]] during [[cardiac]] [[systole]]
**Utilized [[Surgery|surgically]] to pass surgical [[Clamp connection|clamps]] or place [[Ligature|ligatures]] around [[great arteries]].
*[[Oblique sinus]]:
**A blind recess (cul-de-sac) [[posterior]] to the [[left atrium]] between [[superior vena cava]], right and left [[pulmonary vein]]s inferior to the [[Transverse sinuses|transverse sinus]]
**Formed [[Embryonic|embryonically]] by the incorporation of the [[pulmonary vein]] [[tributaries]] into the [[left atrium]]
**Functional role believed to be the expansion of the [[left atrium]] upon normal [[collapse]] of the [[thorax]]

====Diseases of the Pericardium====
 
* [[Pericarditis]] is an [[inflammatory]] condition of the [[pericardium]].
* [[Pericardial effusion]] is [[fluid]] accumulation in the [[pericardial sac]].
* [[Constrictive pericarditis]] occurs when there is a [[scar]] encasing, the [[heart]] that [[Chronic (medicine)|chronically]] constricts the filling of the [[heart]].
* [[Cardiac tamponade]] is a [[medical emergency]] in which [[fluid]] in the [[pericardial sac]] [[Acute (medicine)|acutely]] restricts the filling of the [[heart]]. This requires [[Surgery|surgical]] drainage or [[pericardiocentesis]].

Overview

Pericarditis is inflammation of the pericardium, which is the double-walled sac that contains the heart and the roots of the great vessels. There can be an accompanying accumulation of fluid that can be either serous (free flowing fluid) or fibrinous (an exudate, which is a thick fluid composed of proteins, fibrin strands, inflammatory cells, cell breakdown products, and sometimes bacteria). Vascular congestion of the pericardium is also present. The underlying myocardium may or may not be inflamed as well. If the myocardium is involved in the inflammatory process, it is called myopericarditis, and CK and troponin levels may be elevated. Cardiotropic viruses usually spread to the myocardium and pericardium hematogenously and cause acute inflammation with infiltration of polymorphonuclear (PMN) leukocytes and pericardial vascularization. Most patients with viral pericarditis recover completely with few developing recurrences. Some patients develop constrictive pericarditis which could be disabling. Bacterial pericarditis results from contiguous spread of infection within the chest, either de novo or after surgery or trauma, spread from infective endocarditis, hematogenous, or direct inoculation as a result of penetrating injury or cardiothoracic surgery.

Pathogenesis

  1. Contiguous spread of infection within the chest, either de novo or after surgery or trauma.
  2. Spread from infective endocarditis
  3. Hematogenous spread of infection
  4. Direct inoculation as a result of penetrating injury or cardiothoracic surgery
These types of granulomatous pericarditis also occur with fungal infections, rheumatoid arthritis (RA), and sarcoidosis.
