TREATMENT
■ Treat underlying etiology.
■ ASA or NSAIDs for anti-inflammatory effects and pain control
■ Narcotics for intractable pain
■ Steroids in patients with ongoing symptoms after infectious etiology excluded
■ Mild cases attributed to viral origin can usually be managed as outpatients.
COMPLICATIONS
■ Pericardial tamponade
■ Constrictive pericarditis
■ Fibrotic change reduces diastolic filling.
■ Kussmaul’s sign: increase in JVP during inspiration
■ “Dip and plateau” LV filling (or diastolic) tracing
Pericardial Effusion and Tamponade
While cardiac tamponade results from a pericardial effusion, not all effusions
cause tamponade. An effusion that develops slowly allows for the pericardium
to stretch and the LV volume to increase in response to the fluid, decreasing
the likelihood of tamponade.

Steroids are used in chronic
pericarditis and in patients
who cannot tolerate NSAIDs.
