==Overview==
== [[Pericarditis overview|Overview]] ==


'''Pericarditis''' is an [[inflammation]] of the [[pericardium]] (the fibrous sac surrounding the heart). Pericarditis is further classified according to the composition of the inflammatory [[exudate]]: serous, purulent, fibrinous, and hemorrhagic types occur.
== [[Pericardium|Pericardial Anatomy]] ==


[[Acute pericarditis]] is more common than chronic pericarditis, and can occur as a complication of infections, immunologic conditions, or heart attack.
== [[Pericarditis classification|Classification]] ==


==Pathophysiology & Etiology==  
== [[Pericarditis pathophysiology|Pathophysiology]] ==


Pericarditis is inflammation of the [[pericardium]], 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 inflammed as well. If the myocardium is involved in the [[inflammatory process]], then this is called myopericarditis, and the [[CK]] and [[troponin]] may be elevated.

The signs and symptoms of acute pericarditis can be misleading because they can occur as part of a constellation of symptoms associated with another illness.

# '''Infectious:'''
== Treatment ==
#* Viral: [[Coxsackie B Virus]], [[Echovirus]], [[Adenovirus]] (less commonly: [[Mumps]], [[Influenza]], [[varicella]], [[Hepatitis B]] and [[CMV]]-especially in [[HIV]] patients.) Usually associated with a viral prodrome and acute pericarditis.
[[Pericarditis treatment|Medical Therapy]] | [[Pericardiocentesis]] | [[Pericardial window|Pericardial Window]] | [[Pericardial stripping|Pericardial Stripping]] | [[Treatment Related Videos]]
#* [[Tuberculosis]]: usually bloody, protein greater than 2.5. Initially mostly [[polymorphonuclear cells]], later [[lymphocytes]], [[monocytes]] and [[plasma cells]].  Usually develops very slowly with significant fibrous reaction.  Initially effusive then becomes constrictive.
#* Purulent: [[Pneumococcus]], [[Streptococcus]] and [[Staphylococcus]] most common.  Also Proteus, [[E.coli]], Psuedomonas, [[Klebsiella]], [[Brucellosis]], [[Salmonella]], [[Neisseria]], [[Haemophilus influenza]], [[Tularemia]], [[Legionella]], preodominantly by hematogenous spread and approximately 20% by contiguous spread.  Usually these patients are quite ill.
#* Fungal: [[Histoplasmosis]], [[Coccidiomycosis]], [[Aspergillus]], [[Blastomycosis]], [[Candida]].
#* Other: [[Toxoplasmosis]], [[Amebiasis]], [[Mycoplasma]], [[Nocardia]], [[Actinomycosis]], [[Echinococcus]], [[Lyme disease]] (usually myopericarditis associated with conduction abnormalities). 
# '''Neoplastic:'''
#* Predominantly lung, breast, [[leukemia]], [[lymphomas]] ([[Hodgkins]] and non-Hodgkins).  Less commonly GI malignancies, [[ovarian cancer]], [[sarcoma]]s and [[melanoma]]s, metastic, hematogenous, [[carcinoma]], [[carcinoid]], [[Sipple syndrome]], [[mesothelioma]], [[fibroma]], [[lipoma]] .  Also [[Kaposis sarcoma]] in [[HIV]] positive patients.
# '''Uremic:'''
#* [[Uremic]] pericarditis is seen in up to 20% of uremic patients requiring chronic hemodialysis.  The mechanism is unknown.  Most commonly there is a small effusion associated with pain and a [[pericardial friction rub]], but there can be a large effusion and present with [[tamponade]].
# '''Autoimmune:'''
#* [[Systemic Lupus Erythematosus]] or [[SLE]]: Pericarditis usually occurs in the setting of disease flares (systemic symptoms, high erythrocyte sedimentation rate ([[ESR]]) , +ANA, +dsDNA, [[pleural effusion]]s).  Occurs in 20-40% of patients with [[SLE]] during the course of the disease.  Usually the fluid is serous or grossly bloody.  Analysis of the fluid usually reveals a high protein and low glucose content.  Typically [[WBC]] count is less than 10K, and is made up of primarily [[polymorphonuclear cell]]s ([[PMN]]s). 
#* [[Rheumatoid arthritis]] or [[RA]]: Pericarditis can occur without active joint involvement.  Also serous or bloody.  Usually the protein is > 5 mg/dl, and the glucose is low (<45).  The [[WBC]] is high at 20-90K.  Complement is usually low, and the latex fixation test is usually positive.
#* Other: Acute [[rheumatic fever]], [[scleroderma]], mixed [[connective tissue disease]], [[Wegener's]], [[PAN]].
# '''[[Trauma]]tic:'''
#* After chest trauma, throacic surgery, PCM insertion, [[Valvuloplasty]].  Also from [[esophageal rupture]], pancreatic-pericardial fistula (check amylase), penetrating chest injury, esophogeal perforation, gastric perforation, during catheterization (pacemaker insertion, cathether ablation for [[arrhythmias]], diagnostic, PCI with coronary dissection).
# '''Drugs:'''
#* Usually associated with small effusions.  Common culprits include [[hydralazine]], [[procainamide]], DOH, [[isoniazid]], [[phenylbutazone]], [[dantrolene]], [[doxorubicin]], methylsergide, [[penicillin]].
# '''Hypothyroidism:'''
#* Usually in conjunction with clinically severe [[hypothyroidism]].  Most early case reports associated with [[myxedema]] and patients also had [[ascites]], [[pleural effusion]]s and uveal edema. Often resolves with thyroid replacement therapy.
# '''Other:'''
#* Post-MI ([[Dresslers]]), post-pericardiotomy, [[radiation]], [[dissecting aortic aneurysm]], chylopericardium (from thoracic duct obstruction secondary to tumor, surgical procedure, [[trauma]], [[TB]], congenital).  Also, [[sarcoidosis]], [[amyloidosis]], [[IBD]], [[Whipple's]], [[temporal arteritis]] and [[Behcet syndrome]]).


== Clinical presentation ==
== Case Studies ==
[[Chest pain]], radiating to the back and relieved by sitting up forward and worsened by lying down, is the classical presentation. Other symptoms of pericarditis may include dry [[cough]], [[fever]], fatigue and [[anxiety]]. Pericarditis can be misdiagnosed as [[myocardial infarction]], and vice versa.
[[Pericarditis case study one|Case #1]]


The classic [[medical sign|sign]] of pericarditis is a [[pericardial rub|friction rub]].  Other signs include ST-elevation and PR-depression on [[Electrocardiogram|EKG]] (all leads); [[cardiac tamponade]] ([[pulsus paradoxus]] with [[hypotension]]), and [[congestive heart failure]] (elevated [[jugular venous pressure]] with [[peripheral edema]]).

== History and Symptoms ==
* [[Pericardium]]
A diagnosis of pericarditis can be made depending on its etiology and speed of onset.  For example, both uremic and tuberculosis induced pericarditis develop more slowly and can be undetectable until presenting "as a fever of unknown origin."  On the other hand, both bacterial and viral pericarditis develop rapidly and can present as increasing "pain over several hours." 
 
===Symptoms:===
# [[Chest Pain]]: however, pain is often absent (depending on the type of pericarditis e.g. rheumatoid pericarditis).  It is the most common symptom.
#* Some causes of pain include: inflammation of the pericardium, phrenic nerves, and nearby pleura.
#* Quality of pain: sharp, "sticking", dull, aching, or pressure-like.  It can be rated anywhere from 1-10.  In the beginning stages, the pain usually starts out as sharp.  "Inspiration and cough" can increase the pain so patients usually "sit upright for relief."
# Nonproductive [[cough]] that elicites pleuritic pain
# Productive [[cough]], which usually occurs in the presence of other illness(es)
# [[Hiccup]] (rarely)
# [[Odynophagia]] with or without [[Dysphagia]]
# [[Faintness]] and [[Dizziness]] (uncommon unless [[cardiac tamponade]] is present]]
# [[Chest wall]] [[palpitations]]: causing local tenderness and may be indicative of [[costochondritis]], [[Tietze syndrome]], or [[rib fractures]] (in cases of traumatic pericarditis)
 
== Physical Examination ==
 
=== Appearance of the Patient with Pericarditis ===
# [[Fever]] less than 39&deg; C or 102.2&deg; F
#* Patients who are elderly may not exhibit fever; however, they may be [[hypothermic]] especially those with [[renal failure]].
# [[Chills]] (suppurative pericarditis and idiopathic (viral) pericarditis)
# [[Weakness]]
# [[Depression]]
# [[Anxiety]]
# [[Pallor]] (may also indicate [[tuberculosis]], [[uremia]], [[neoplasia]], and rheumatic carditis)
 
=== Heart ===
'''Ausculatory Phenomena:'''
# Pericardial Rub(s): Usually heard with acute pericarditis, sometimes with subacute and chronic.  This is the major indicator of pericarditis.
#* endopericardial rub: inflamed, scarred or tumor-invaded serosal surfaces
#* exopericardial rub: after sclerotherapy of effusions, between parietal pericardium and pleura or chest wall (occasionally)
#* endo-exopericardial rub: both of the above
#* pleuropericardial rub: [[pleuritis]] as a result of pleural or both pleural and pericardial both
# Abnormal Heart Sounds:
#* Sounds are dampened as a result of fluid insullation
#* Hemodynamic changes diminish S<sub>1</sub> and S<sub>2</sub>
# Clicks: Ventricular volume shrinks disproportionately and psuedoprolapse/true prolapse of mitral and/or tricuspid valvular structures result in clicks.
# Murmurs: are epiphenomena and may be present if there is coinciding heart disease, narrowing of a valve, aorta, pulmonary artery or another area of the heart.
=== Lungs ===
 
[[Rales]] are frequent examination findings, occasionally [[pleural fluid]] may present.
 
=== Extremities ===
#May be poorly perfused in the setting of tamponade
#Edema may be present in the setting of pericardial constriction

'''[[Electrocardiography|ECG Abnormalities]]:''' Increase in scar tissue, fluid and fibrin can reduce voltage, quasi-specific ST-T waves can present. The [[ECG]] abnormalities vary depending on the stage/severity of the pericarditis.  Below are the stages/types of pericarditis:<!--

#''Acute Pericarditis'' (see also [[Electrocardiography#The PR Interval]] and [[Electrocardiography#The EKG of Cardiac Transplantation]]): this variation of the disease in conjunction with myocarditis can lead to ST-T anomalies that are characteristic of the acute stages of pericarditis.
#*''Stage 1'': Stage 1 of acute pericarditis, in and of itself, presents as "early repolarization" and acute infarction.  It shows signs of anterior and inferior ST elevation on the [[ECG]].  There are usually no deviations in the QRS complex.  This stage is largely characteristic of acute pericarditis when almost all of the leads are effected.  Leads I, II, avL, avF, and V<sub>3</sub>-V<sub>6</sub>.
#*''Stage 2'': During the early phase of this stage, ST segments should become baseline again; whereas, PR segments may have deviated.  During the latter phase of stage 2, the ST segments that were previously elvated usually flatten and invert.
#*''Stage 3'': Virtually all of the leads in stage 3 exhibit T wave inversion.  Acute pericarditis cannot be diagnosed on an [[ECG]] of a stage 3 patient because its presentation is the same as myocardial injury and frank myocarditis.
#*''Stage 4'': This stage presents itself on the [[ECG]] as a return to a prepericarditis state.  Stage 4 does not always occur and in its absence, there can be residual T wave inversions that may be permanent, generalized or focal. 
#''Rate and Rhythm'': Rapid heart rates are typical in patients with pericarditis, but in patients with uremic pericarditis slower rates are observed.  Heart rhythms appear normal unless there is another complication such as cardiac disease, the presence of myocardial/pericardial tumor, or a metabolic disorder.
#''[[Pericardial Effusion]]'' (see also [[Electrocardiography#Amplitude]]): These can present differently on the [[ECG]] depending on whether they are chronic vs large effusions.  The former typically leads to low amplitude [[ECG]]s; whereas, the latter can show no voltage or various [[Electrocardiography|ECG abnormalities]].  ST-T wave abnormalities can be caused by superficial myocarditis or because of the accumulated fluid, they may be caused by the compression of the myocardium or [[ischemia]].  The primary cause of ST segment variation during pericardial effusions is usually the rapid accumulation of fluid.  Large effusions can lead to the reduction of P wave voltage.  [[Pleural effusions]] can cause a decrease in voltage, which occurs mainly on the left.  Also, [[cirrhosis]] and [[congestive heart failure]] ([[CHF]]), which similarily involve the accumulation of fluid in the body, can decrease voltage in the absence of any pericardial disease.
#''[[Cardiac tamponade]]'' (see also [[Cardiac tamponade#Electrocardiogram]]): Generally has little [[ECG]] effect; however, in the acute form, tamponade may present on the [[ECG]] as any one of the stages of acute pericarditis.   
#''Electrical Alternation'': This occurs more often in cases of tamponade than in those of pericarditis (2:1).  There is alternation of the QRS complex on the spatial axis.  Alternation of the T wave, P wave, and PR segement are difficult to see and are uncommon.  The removal of even a small amount of fluid can end alternation.
#''Early Repolarization'': This finding can be misleading and may look like pericarditis, when in fact it is not.  A strong indication of pericarditis is "if the J point is more than 25% the height of the T wave apex."
#''Constrictive Pericarditis'': Cases of constrictive pericarditis have nonspecific [[ECG]] abnormalities.  Common abnormalities include: a slightly "low voltage QRS" segment combined with "flattened to inverted T waves", during stage 3 of acute/subacute constriction the T wave inversions remain or worsen and "P waves can be wide and bifid."  It is not uncommon for patients to have normal [[ECG]]s.  Many patients may only exhibit "nonspecific T wave abnormality."  Other influencial factors that may effect the [[ECG]] in constrictive pericarditis are: [[fluid retention]], [[ascites]], and [[pleural effusions]].  The two most common [[arrhythmias]] that occur are [[atrial fibrillation]] and [[atrial flutter]].   
#*''QRS Abnormality'': characteristic RV hypertrophy QRS abnormalities may develop as a result of disproportionate constriction or postpericardiectomy scarring.  Also, "focal atrophy, scarring or inflamation" may cause "abnormal Q waves."
#**''Chronic Constrictive Pericarditis'': low volatage and myocardial atrophy, "frontal QRS axis" is usually vertical (becomes more vertical with increasing chronicity),
#**''Acute/Subacute Pericarditis'': QRS axis appears as normal

'''Pericardial Effusion'''
 
Cross-sectional imaging by CT or MRI is very sensitive in the detection of generalized or loculated pericardial effusions. Some fluid in the pericardial sac contributes to the apparent thickness and should be considered normal. Commonly, free-flowing fluid accumulates first at the posterolateral aspect of the left ventricle, when the patient is imaged in the supine position.
 
Estimation of the amount of fluid is possible to a limited extent based on the overall thickness of the crescent of fluid. Compared to cardiac ultrasound, CT and MRI may be particularly helpful in detecting loculated effusions, owing to the wide field of view provided by these techniques. Hemorrhagic effusions can be differentiated from a transudate or an exudate based on signal characteristics (high signal on T1-weighted images) or density (high-density clot on CT). Pulsation artefacts may cause local areas of low signal in a hemorrhagic effusion. Effusions are often incidentally noted on CT scans obtained for other indications.
 
Pericardial thickening (thickness >4 mm) is difficult to differentiate from a small generalized effusion. Both entities will reveal a low signal/density line that is thicker than the normal pericardial thickness. In acute pericarditis, the pericardial lining can show intermediate signal intensity and may enhance after gadolinium administration.

'''Constrictive Pericarditis'''
 
Pericardial thickening may result in constrictive pericarditis. In this entity, pericardial thickening will hamper cardiac function, with hemodynamic consequences. Many disease conditions can lead to constrictive pericarditis (infection, tumor, radiation, heart surgery, etc.).
 
The diagnostic features include thickened pericardium in conjunction with signs of impaired right ventricular function: dilatation of caval veins and hepatic veins, enlargement of the right atrium, and the right ventricle itself may be normal or even reduced (tubular, sigmoid) in size due to compression. Localized pericardial thickening may also cause functional impairment (localized constrictive pericarditis). Sometimes constriction may occur despite a normal appearance of the pericardium.
 
Pericardial calcifications are easily visualized by CT but may be difficult or impossible to appreciate on MRI.
 
'''Pericardial Tumor'''
 
A pericardial cyst is most commonly located at the right cardiophrenic angle. On T1, it appears either as a low signal or an intermediate signal due to high protein content, or with a characteristic light-bulb appearance on T2.
 
Unusual tumors may arise from the pericardium (mesothelioma, angiosarcoma, etc.). Malignant primary tumors have many overlapping imaging features and generally cannot be differentiated. The role of cross-sectional imaging is to establish a diagnosis and to define the extent of the lesion (invasion of cardiac structures, veins, pericardium, etc.). Sometimes lesions may have helpful signal characteristics to suggest a specific diagnosis, e.g., high-signal fat on T1 or low-density fat on CT in lipoma / liposarcoma.
 
Secondary tumors are much more common than primary tumors. Lung cancer may invade the mediastinal and cardiac structures directly or indirectly.
 
The most common secondary tumors affecting the heart are lung cancer, breast cancer, and lymphoma. Metastatic pericardial disease commonly presents as hemorrhagic effusion. Tumor nodules may enhance after intravenous gadolinium administration.

==Differential Diagnosis for Diseases of the Pericardium ==
 
Many other conditions produce signs and symptoms similar to those produced by pericarditis.  Keep in mind that pericarditis might also be one of the following: "part of a generalized disease", "apparently isolated", or "part of a disease that affects a nearby organ", and "sometimes is the presenting syndrome of multiple diseases."
 
'''Key Signs & Symptoms to Differentiate Pericarditis:'''
# Pain on the trapezius ridge(s), is a pathognomonic of pericarditis.  Often pain can radiate mimicking pain that is commonly felt during angina.
# Central pleuritic chest pain (can also be indicative of pleurisy; however, may be both)
# Pain that lasts longer, is sharper and unresponsive to vasodilator therapy (similar "to that of cardiac ischemia")
# Most acute pericarditis ECGs are similar to ECGs of ischemic heart disease rather than infarction
# [[Pulmonary embolism]] can present similarly to pericarditis, but can be differentiated from pericarditis in the presence of one of the following findings: a nonspecifically altered ECG, a plerual rub,  and non-precordial (someitmes precordial pain is present regardless).

== Treatment ==
 
The majority of patients with pericarditis are hospitalized so they can be observed and monitored for complications while they recover.  The treatment of viral or idiopathic pericarditis is with [[non-steroidal anti-inflammatory drug]]s.  Patients should be observed for side effects since [[NSAID]]s are known to effect the GI mucosa.
 
Severe cases of pericarditis may require:
* [[pericardiocentesis]]
* [[antibiotic]]s
* [[steroid]]s
* [[colchicine]]
* [[surgery]]
 
Patients with uncomplicated acute pericarditis can generally be treated and followed up in an outpatient clinic. However, those with high risk factors for developing complications (see above) will need to be admitted to an inpatient service, most likely an ICU setting. High risk patients include:<!--

* subacute onset
* high fever (> 100.4 F) and [[leukocytosis]]
* development of [[cardiac tamponade]]
* large [[pericardial effusion]] (echo-free space > 20 mm) resistant to [[NSAID]] treatment
* immunocompromised
* history of oral anticoagulation therapy
* acute trauma
* failure to respond to seven days of NSAID treatment.
 
===Usual Steps in Treatment of Pericarditis===
 
'''''[[Pericardiocentesis]]''''' is a procedure whereby the fluid in a pericardial effusion is removed through a needle. It is performed under the following conditions:<!--
  --><ref name="maisch2">{{cite journal | author=    Maisch B, Seferovic PM, Ristic AD, Erbel R, Rienmuller R, Adler Y, Tomkowski WZ, Thiene G, Yacoub MH | title=  Guidelines on the diagnosis and management of pericardial diseases executive summary; The Task force on the diagnosis and management of pericardial diseases of the European Society of Cardiology | journal=  Eur Heart J | year=2004 | pages=587–10 | volume=25 | issue=7 | pmid=15120056 | doi=  10.1016/j.ehj.2004.02.002}}</ref>
* presence of moderate or severe cardiac tamponade
* diagnostic purpose for suspected purulent, tuberculosis, or neoplastic pericarditis
* persistent symptomatic pericardial effusion
 
'''''[[NSAIDs]]''''' in ''viral'' or ''idiopathic'' pericarditis. In patients with underlying causes other than viral, the specific etiology should be treated. With idiopathic or viral pericarditis, NSAID is the mainstay treatment. Goal of therapy is to reduce pain and inflammation. The course of the disease may not be affected. The preferred NSAID is [[ibuprofen]] because of rare side effects, better effect on coronary flow, and larger dose range.<!--
  --><ref name="maisch2">{{cite journal | author=    Maisch B, Seferovic PM, Ristic AD, Erbel R, Rienmuller R, Adler Y, Tomkowski WZ, Thiene G, Yacoub MH | title=  Guidelines on the diagnosis and management of pericardial diseases executive summary; The Task force on the diagnosis and management of pericardial diseases of the European Society of Cardiology | journal=  Eur Heart J | year=2004 | pages=587–10 | volume=25 | issue=7 | pmid=15120056 | doi=  10.1016/j.ehj.2004.02.002}}</ref> Depending on severity, dosing is between 300-800 mg every 6-8 hours for days or weeks as needed. An alternative protocol is [[aspirin]] 800 mg every 6-8 hours.<!--
  --><ref name="imazio2">{{cite journal | author=  Imazio M, Demichelis B, Parrini I, Giuggia M, Cecchi E, Gaschino G, Demarie D, Ghisio A, Trinchero R | title=  Day-hospital treatment of acute pericarditis: a management program for outpatient therapy | journal=  J Am Coll Cardiol | year=2004 | pages=1042–6 | volume=43 | issue=6 | pmid=15028364 | doi=  10.1016/j.jacc.2003.09.055}}</ref> Dose tapering of NSAIDs may be needed. In pericarditis following acute myocardial infarction, NSAIDs other than aspirin should be avoided since they can impair scar formation. As with all NSAID use, GI protection should be engaged. Failure to respond to NSAIDs within one week (indicated by persistence of fever, worsening of condition, new pericardial effusion, or continuing chest pain) likely indicates that a cause other than viral or idiopathic is in process.
 
'''''[[Colchicine]]''''' can be used alone or in conjunction with NSAIDs in prevention of recurrent pericarditis and treatment of recurrent pericarditis. For patients with a first episode of acute idiopathic or viral pericarditis, they should be treated with an NSAID plus colchicine 1-2 mg on first day followed by 0.5 daily or BID for three months. <!--

'''''[[Corticosteroids]]''''' are usually used in those cases that are clearly refractory to NSAIDs and colchicine and a specific cause has not been found. Systemic corticosteroids are usually reserved for those with autoimmune disease.
 
== Pharmacotherapy ==
 
=== Acute Pharmacotherapies ===
As previously mentioned, the typical pharmacotherapy in viral or idiopathic pericarditis is with [[NSAID]]s. These drugs have analgesic, antipyretic and anti-inflammatory effects. The most prominent members of this group of drugs are [[aspirin]] and [[ibuprofen]]. [[Paracetamol]] ([[acetaminophen]]) has negligible anti-inflammatory activity. 
 
=== Chronic Pharmacotherapies ===
Severe cases may require one of the aforementioned procedures or one of the alternative pharmacotherapies listed below:
:* Antibiotics
:* Steroids
 
==Surgical and Device Based Therapies==
===[[Pericardiocentesis]]===
===[[A thoracoscopic approach to creating a pericardial window]]===
 
===[[A surgical subxiphoid incision to create a pericardial window]]===
 
=== Pericardial Stripping for Constrictive Pericarditis===
 
The definitive treatment for constrictive pericarditis is pericardial stripping, which is a surgical procedure where the entire [[pericardium]] is peeled away from the heart. This may be effective in up to 50% of patients. This procedure has significant risk involved, since the thickened [[pericardium]] is often adherent to the [[myocardium]] and coronary arteries.
 
In patients who have undergone [[coronary artery bypass surgery]] with pericardial sparing, there is danger of tearing a bypass graft while removing the pericardium. If any pericardium is not removed, it is possible for bands of pericardium to cause localized constriction which may cause symptoms and signs consistent with constriction.

==Complications==
 
===Fibrinous pericarditis===
 
[[Image:Pericarditis fibrinosa.jpg|thumb|Pericarditis fibrinosa]]
Fibrinous pericarditis is an [[exudative]] [[inflammation]]. The pericardium is infiltrated by the fibrinous exudate. This consists of [[fibrin]] strands and [[leukocytes]]. Fibrin describes an amorphous, [[eosinophilic]] (pink) network. Leukocytes (mainly [[neutrophils]]) are found within the fibrin deposits and intrapericardic. Vascular congestion is also present. The myocardium has no changes. Sometimes referred to as having "Bread and Butter Appearance".  Photo at: [http://www.pathologyatlas.ro/Fibrinous%20Pericarditis.html Atlas of Pathology]
 
===Pericarditis due to tuberculosis===
Pericarditis caused by [[tuberculosis]] is difficult to diagnose, because definitive diagnosis requires culturing ''[[Mycobacterium tuberculosis]]'' from aspirated [[pericardium|pericardial]] fluid or pericardial [[Wiktionary:biopsy|biopsy]], which requires high technical skill and is often not diagnostic (the yield from culture is low even with optimum specimens). 
 
The [[Tygerberg score|Tygerberg scoring system]] helps the clinician to decide whether pericarditis is due to tuberculosis or whether it is due to another cause:
 
* Night sweats (1 point),
* Weight loss (1 point),
* Fever (2 point),
* Serum globulin &gt; 40g/l (3 points),
* Blood total leucocyte count &lt;10 x 10<sup>9</sup>/l (3 points);
 
A total score of 6 or more is highly suggestive of tuberculous pericarditis.<ref>{{cite journal | author=Reuter H, Burgess L, van Vuuren W, Doubell A. | title=Diagnosing tuberculous pericarditis | journal=Q J Med | year=2006 | volume=99 | pages=827&ndash;39 | pmid=17121764 }}</ref> 
 
Pericardial fluid with an [[interferon-gamma|interferon-γ]] level greater than 50[[Wiktionary:picogram|pg]]/ml is highly specific for tuberculous pericarditis.
 
The definitive treatment for constrictive pericarditis is pericardial stripping, which is a surgical procedure where the entire pericardium is peeled away from the heart.  This procedure has significant risk involved,<ref name="Cinar-2006">{{cite journal | author=Cinar B, Enc Y, Goksel O, Cimen S, Ketenci B, Teskin O, Kutlu H, Eren E. | title=Chronic constrictive tuberculous pericarditis: risk factors and outcome of pericardiectomy | journal=Int J Tuberc Lung Dis | year=2006 | volume=10 | issue=6 | pages=701–6 | pmid=16776460}}</ref> with mortality rates of 6% or higher in major referral centers.<ref name="Chowdhury-2006">{{cite journal | author=Chowdhury UK, Subramaniam GK, Kumar AS, Airan B, Singh R, Talwar S, Seth S, Mishra PK, Pradeep KK, Sathia S, Venugopal P | title=Pericardiectomy for constrictive pericarditis: a clinical, echocardiographic, and hemodynamic evaluation of two surgical techniques | journal=Ann Thorac Surg | year=2006 | volume=81 | issue=2 | pages=522–9 | pmid=16427843 | doi=10.1016/j.athoracsur.2005.08.009}}</ref><ref name="Ling-1999">{{cite journal | author=Ling LH, Oh JK, Schaff HV, Danielson GK, Mahoney DW, Seward JB, Tajik AJ | title=Constrictive pericarditis in the modern era: evolving clinical spectrum and impact on outcome after pericardiectomy | journal=Circulation | year=1999 | volume=100 | issue=13 | pages=1380–6 | pmid=10500037}}</ref>  The high risk of the procedure is attributed to adherence of the thickened pericardium to the [[myocardium]] and [[coronary arteries]].  In patients who have undergone [[coronary artery bypass surgery]] with pericardial sparing, there is danger of tearing a bypass graft while removing the pericardium.
