Pericarditis is a disorder caused by inflammation of the pericardium, the sac-like covering of the heart. Pericarditis can be caused by bacterial, fungal, or viral infections. It may also be a result of injury or trauma to the chest, esophagus, or heart. Pain occurs as a result of the inflamed pericardium rubbing against the heart.
