Pericarditis is a disorder caused by inflammation of the pericardium, which is the sac-like covering around the heart. Causes, incidence, and risk factors: Pericarditis is usually a complication of viral infections, most commonly echovirus or coxsackie virus.reatment depends on the underlying cause, how much fluid is present, and how quickly it is enlarging the pericardium (thin layer of tissue surrounding the heart). Treatment of the underlying disorder, such as an infection, heart failure, kidney failure, or malnutrition, generally reduces or eliminates the excess fluid.
The most common cause of fluid accumulation around the heart is inflammation of the sac or lining surrounding the heart. However, in many cases, the cause may not be found. Possible causes include: An autoimmune reaction like lupus or rheumatoid disease.
