Line 1: Line 1:
 +(1) The surgical removal of part or most of the pericardium. This operation might be done to relieve constrictive pericarditis,​ or to remove a pericardium that is calcified and fibrous.
 +ICD-9 code: 37.31 
 +MeSH D010492 ​
 +The pericardium is a sac which surrounds the [[heart]] and is filled with a viscous fluid that lubricates
 +the outside of the heart to allow for efficient contractions. After a bout of [[pericarditis]] ([[inflammation]] of the pericardium caused by [[infection]],​[[autoimmune disease]], open heart [[surgery]],​ etc.), the pericardium becomes thickened and can adhere to the outer surface of the heart. When this is severe, constrictive pericarditis develops which is manifest as right heart failure. In right heart failure, blood backs up into the [[liver]] causing abdominal fluid retention and distension, elevated venous pressure, and shortness of breath. Right heart failure results because [[blood]] returning to the right side of the heart does not sufficiently empty into the heart since the thickened pericardium constrains the right [[ventricle]] from expanding enough to receive the venous blood. A complete pericardiectomy can be done by a cardiac surgeon who would manually strip the entire pericardium off the outer surface of the heart.
