Pericardial Diseases

Show Summary Details


The pericardium is a fibromembranous inelastic sac less than 2 mm in thickness that comprises 2 distinct layers. The outer inelastic fibrous layer anchors the heart in the mediastinum with attachments anteriorly to the manubrium and xiphoid process, posteriorly to the vertebral column, and inferiorly to the diaphragm. The inner serous double layer is divided into the visceral pericardium and the parietal pericardium. The pericardium serves as a protective nondistensible mechanical barrier for the heart by containing and protecting it from acute overdistention. This chapter examines the following pericardial conditions: congenital absence of the pericardium, pericardial cyst, acute pericarditis, pericardial effusion and cardiac tamponade, constrictive pericarditis, restrictive cardiomyopathy, and infilitrative cardiomyopathy.
