Pediatric intact pericardium showing the heart covered by the pericardial sac. There are two longitudinal structures running in a cephalad-to-caudal direction on the mediastinal surface of the pericardial sac. These correspond to the right and left borders of the sternopericardial ligament. The pericardiophrenic ligaments are barely visible on the left and right margins of the pericardial sac.
