The pericardium is a double-walled sac that encloses the heart. The outer sac is called the “fibrous pericardium,” and the inner sac is called the “serous pericardium.” The serous pericardium is composed of an outer (parietal) layer, and an inner (visceral) layer separated by potential space (pericardial cavity). Both the fibrous and the serous layers are continuous with the adventi-tia of the great vessels.
