3. 1) Anatomy of pericardium
2) Overview of pericardial disease
3) Clinical presentation
4) Acute pericarditis
5) Chronic pericarditis

4.  Normal amount of
pericardial fluid: 15-50
cc
 Two layers:
 Outer layer is the parietal
pericardium and consists
of layers of fibrous and
serous tissue
 Inner layer is visceral
pericardium and consists
of serous tissue only

5.  Fibroelastic sac
consisting of 2 layers
 Visceral at
epicardial side
 Parietal at
mediastinal side
 Pericardial fluid
formed from
ultrafiltrate of plasma

6.  Acute Pericarditis
 Chronis pericarditis
 Pericardial Effusion

11.  Serous
 Fibrinous
 Purelent
 Hemorrahgic
 Caseous

12.  50-200ml exudate
 Etiology unknown

13.  Scant acute and ch
inflammatory
infiltrate
 Fluid reabsorb leaving
any residual change

14.  Most commonly seen
in MI
 Associated with
friction rub

15.  Fibrin strands
 Inflammatory exudate
 Congested capillaries
 Exudate can
completely resolve or
can organize leaving
delicate, stringy
adhesions or plaque
like thickening.

16.  Usually signifies
bacterial, fungal or
parasitic infection
 Direct extension,
hematogenous or
lymphatic spread.
 Common organisms
streptococci,
staphylococci and
pneumococci

17.  400- 500 ml
 Thin to creamy pus
 Erythematous,
granular surface
 Can produce
constrictive
pericarditis

18.  Exudate of blood
admixed with
fibrinous to
supparative effusion
 Most commonly it
follows cardiac
surgery or associated
with tuberculosis or
malignancy
 It organize with or
without calcification

19.  Due to tuberculosis
 Typically by direct
extension from
neighboring lymph
nodes or less
commonly mycotic
infection
 Lead to fibro calcific
constrictive
pericarditis.

20.  Central caseous
necrosis
 Epitheliod histiocytes
forming granulomas
 Giant cells.

21.  Healing of acute lesions
 Adhesive medistinopericarditis
 Constrictive pericarditis

22.  Clinically significant
 Pericardial sac obliterated
 Parietal layer is tethered to medistinal tissue
 Heart so contract against the surrounding
attached structures with hypertrophy and
dilatation.

23.  Clinically significant
 Thick dense fibrous obliteration with
calcification of the pericardial sac encasing the
heart limiting diastolic expansion and
restricting cardiac output.

24.  Normal in
patients with
acute pericarditis
unless
pericardial
effusion is
present
 Requires 200cc of
fluid

26.  the historic yield of diagnostic evaluation is
low, typically only in 16% of patients is
etiology determined.
 evaluation of pericardial fluid and tissue with
tumor markers, PCR, immunohistochemistry,
flourescence-activated cell sorting has shown a
trend toward higher yield of diagnosis

27. 1) Chest pain
 Sudden onset
 localized to anterior chest wall
 pleuritic
 sharp
 Positional: may improve if pt leans forward, worse
with lying flat
2) Cardiac auscultation: Pericardial friction rub
 Present in up to 85% of pts with pericarditis without
effusion
 friction of the two inflamed layers of pericardium,
typically triphasic rub, heard with diaphragm of
stethoscope at left sternal border
3) Characteristic ECG changes
4) Pericardial effusion

28.  Elevated C reactive protein level
 strong correlation - normal CRP makes acute
pericarditis diagnosis less likely
 Elevated CK, CK-MB, and Troponin
 Often elevated Troponin alone
 Indicates inflammation of myocardium just
beneath the visceral pericardium
 Not associated with worse outcomes
 Leukocytosis

29.  51yo man with acute onset sharp substernal chest pain
two days prior

30.  Low voltage and Electric Alternans

33.  Pressure in pericardium exceeds pressure in
the cardiac chambers, lower chamber atria
affected before higher pressure ventricles
 Compressive effect is seen best in the phase
when the intrachamber pressure is lowest –
systole for atria and diastole for ventricles
 Diagnostic techniques
 2D looking for RA/RV collapse during diastole
 M-mode for RA/RV collapse during diastole
 Doppler of Mitral and Tricuspid inflow
 Mitral inflow to decrease by 25% with inspiration
 Tricuspid inflow increased by 40% with inspiration
 IVC diameter fails to increase with inspiration
