TY - CHAP M1 - Book, Section TI - Pericardial Disease A1 - O’Connor, Matthew J. A2 - Kline, Mark W. PY - 2018 T2 - Rudolph's Pediatrics, 23e AB - The pericardium serves as the external protective layer of the heart, providing a barrier to trauma, malignancy, inflammation, and infection. In addition, a thin layer of fluid within the pericardial space lubricates the heart, thereby reducing the energy expenditure and shear stress encountered with cardiac motion. A basic understanding of the anatomy and physiology of the pericardium and pericardial space is necessary to recognize and properly diagnose disease processes affecting this important structure.
