The pericardium is a fibroserous sac which is located in the middle mediastinum and encloses the heart and the roots of the great vessels. It has the appearance of a truncated cone with its base resting on and fused with the central portion of the diaphragm. Its blunt apex reaches the level of the second costal cartilage (Figs. 249 and 250). The outline of the pericardium corresponds to that of the heart except that it reaches the 2nd costal cartilage on both sides, whereas the heart extends only to the 3rd cartilage on the right.
