Pericardiectomy is the surgical removal of part or most of the pericardium. This operation is most commonly done to relieve constrictive pericarditis or to remove a pericardium that is calcified and fibrous. There are many etiologies for constrictive pericarditis and it is better to know the exact cause as the post operative morbidity, mortality, and life expectancy are strongly influenced by the cause.
