The pericardium is one of the serosal cavities of the mammals. It consists of two anatomical structures closely connected, an external sac of fibrous connective tissue, that is called fibrous pericardium and an internal that is called serous pericardium coating the internal surface of the fibrous pericardium (parietal layer) and the heart (visceral layer) forming the pericardial space. Between ...

Pericardial patch grafts were implanted in the hearts of young sheep for periods ranging from two to 120 days. Explants seven to 21 days old revealed the formation of a "pseudoneointima" (PNI) on the blood contacting surface of the pericardium. The PNI was more heavily mineralized than the pericardium. Mineralization was most intense on the blood contacting surface of the PNI and on the chamber...

the relation between microchimerism and allograft tolerance is still a mystery. in this study we determined the presence of peripheral blood microchimerism (pbmc) in female renal transplant recipients from living male donors with second round polymerase chain reaction (pcr). second round pcr was used to find y chromocome products. the degree of pbmc in renal transplant recipinents must be below...

pericardium in children, the two most important of which are? (i) that adherent pericardium is the most common cause of enlarged heart in children, and (2) that this sequence of pericarditis is much more serious in its nature than valvular disease, and that children in whom it is present will probably never reach adult life. These facts are not new; but although known to those who have had expe...

A diverticulum of the pericardium can often be confused with other lesions of the heart and great vessels as well as mediastinal cysts and other masses. Pericardial effusion, sometimes associated with heart lesions causing cardiac enlargement, is a frequent factor in producing diverticular formation. The mode of development of a pericardial diverticulum is better appreciated when certain featur...

By using excised postmortem hearts obtained from 15 mongrel dogs with the pericardium intact, we investigated mechanical interactions between the four heart chambers from the standpoint of ventricular pressure-volume relationships. The interactions investigated were those between (1) the atrium and the ventricle, (2) the right ventricle and left ventricles, (3) the atrium and one ventricle vs. ...

OBJECTIVE Anticalcification strategies of glutaraldehyde-fixed xenograft tissue aim to extract lipids or to neutralize toxic aldehyde residuals. The purpose of this study was to evaluate the efficacy of octanediol compared to standard treatments of glutaraldehyde-fixed bovine pericardium in the subdermal rat model. Octanediol treatment is an ethanolic solution (40%) containing a long chain alip...

S = support of heart afforded by the pericardium T = tone of muscle. The support of the pericardium is due to the negative pressure in the pericardial cavity which I have shown is present in health. This negative pressure causes a suction action which keeps the pericardium right up against the heart save for the thin layer of pericardial fluid so necessary for lubrication. F varies directly wit...

Pericardial cysts are rare benign lesions of the thoracic cavity and are mostly congenital anomalies. They are induced by an incomplete coalescence of foetal lacunae during the development of the pericardium. Pericardial cysts are usually unilocular, well marginated spherical or teardrop shaped and may be attached to the pericardium directly or by a pedicle. Of all pericardial cysts, 70 to 75% ...
