The visceral pericardium is continuous with the epicardial surface of the heart. The parietal pericardium is a dense but thin fibrous structure that is apposed to the pleural surfaces laterally and blends with the central tendon of the diaphragm inferiorly. Around the right and left ventricles RV and LV and the ventricular apex the pericardial space is a simple ellipsoid structure conforming to the shape of the ventricles. Around the systemic and pulmonary venous inflows and around the great vessels the parietal and visceral pericardia meet to close the ends of the sac these areas often are referred to as pericardial reflections. The pericardial space encloses the right atrium RA and RA appendage anteriorly and laterally with pericardial reflections around the superior and inferior vena cavae near their junction with the RA. Superiorly the pericardium extends a short distance along the great vessels with a small pocket of pericardium surrounding the great arteries posteriorly the transverse sinus. The .
