Answer

Bacterial infections accounts for 1-8% of pericarditis cases and result from direct pulmonary extension, hematogenous spread, myocardial abscess or endocarditis, penetrating injury to chest wall from either trauma or surgery, or a subdiaphragmatic suppurative lesion. Purulent pericarditis may result from previous aseptic pericarditis, and a high percentage of patients develop constrictive pericarditis.
