Clinical Information

Pericardium - A conical fibro-serous sac surrounding the HEART and the roots of the great vessels (AORTA; VENAE CAVAE; PULMONARY ARTERY). Pericardium consists of two sacs: the outer fibrous pericardium and the inner serous pericardium. The latter consists of an outer parietal layer facing the fibrous pericardium, and an inner visceral layer (epicardium) resting next to the heart, and a pericardial cavity between these two layers.

Pneumopericardium - Presence of air or gas in the space between the heart and the PERICARDIUM. The degree of respiratory distress depends on the amount of trapped air and circulation blocked in the systemic and pulmonary veins.
