Normal pericardium Pericardial Layers: Visceral layer Parietal layer Fibrous pericardium
Anatomy of pericardium thin avascular sac comprising two layers ; the visceral and parietal pericardium encompass the heart and a portion of the adjoining great vessels Sagristà-Sauleda J, et al. N Engl J Med 2004; 350:469-475 Faisal FS, et al. Heart Fail Rev 2013; 18:277-287
Normal pericardium
Normal pericardium Normally <2 mm thick normal amount of pericardial fluid is < 50 ml transudative with a low protein content pressure differential between the pericardium and the cardiac chambers (transmural pressure) is about 3 mm Hg
The role of pericardium 1. provides structural support 2. optimizes cardiac pressure volume relationships 3. act as barrier to infection, metastasis.. Spodick DH. 1997 Marcel Dekker, New York Faisal FS, et al. Heart Fail Rev 2013; 18:277-287

Pericarditis
Constrictive pericarditis Constrictive pericarditis was recognized at autopsy in the 19th century and described as a chronic fibrous callous thickening of the wall of the pericardial sac that is so contracted that the normal diastolic filling of the heart is prevented
The difference between the subacute & chronic forms of constrictive pericarditis whether only the visceral pericardium is fused to the epicardium of the heart (subacute) both the visceral and the parietal pericardial layers are fused together (chronic) In both instances, the diastolic pressures in the atria are elevated due to the restriction of ventricular diastolic inflow.

The reported prevalence of ECP among patients with a pericardial effusion has ranged widely, from 1% to 2% to more than 50% Sagrista-Sauleda J, et al. N Engl J Med 2004; 350:469 75. Nugue O, et al.

Effusive Constrictive Pericarditis Clinical hemodynamic syndrome in which constriction of the heart by the visceral pericardium occurs in the presence of tense effusion in a free pericardial space. Sagristà-Sauleda J, et al. N Engl J Med 2004; 350:469-475
The hallmark of effusive constrictive pericarditis persistence of elevated RA pressure after intrapericardial pressure has been reduced to normal levels by removal of pericardial fluid Sagristà-Sauleda J, et al. N Engl J Med 2004; 350:469-475 Faisal FS, et al. Heart Fail Rev 2013; 18:277-287
Definitions of effusive constrictive pericarditis On the basis of hemodynamic findings during combined pericardiocentesis and cardiac catheterization. The diagnostic criterion was tamponade that evolved into constriction (with failure of the RA pressure to fall by 50 % or more or to a level below 10 mm Hg) after intrapericardial pressure was lowered to near 0 mm Hg by the removal of pericardial fluid.
