  2. Pericardial sinus - Wikipedia

    en.wikipedia.org/wiki/Pericardial_sinus

    There are three pericardial sinuses: superior, transverse and oblique. [1] The superior sinus is anterior to the ascending aorta and the pulmonary trunk. [1] It cannot be assessed in electrophysiology procedures. [1] The oblique sinus is an inverted J-shaped reflection of the venae cavae and pulmonary veins. [2]

  3. Pericardium - Wikipedia

    en.wikipedia.org/wiki/Pericardium

    The pericardium (pl.: pericardia), also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. [1] It has two layers, an outer layer made of strong inelastic connective tissue ( fibrous pericardium ), and an inner layer made of serous membrane ( serous pericardium ).

  4. Anatomy of the human heart - Wikipedia

    en.wikipedia.org/wiki/Anatomy_of_the_human_heart

    The transverse recess lies behind the aorta and pulmonary trunk, while the oblique recess lies behind the left atrium. [6] The serous pericardium is thin and covers the heart. It is also called the epicardium. The fibrous pericardium is much thicker. Together they form the pericardial cavity, a thin sac hosting a small amount of fluid. [7]

  5. Pericardial fluid - Wikipedia

    en.wikipedia.org/wiki/Pericardial_fluid

    The pleural and pericardial cavities are exaggerated since normally there is no space between parietal and visceral pleura and between pericardium and heart. Pericardial fluid is the serous fluid secreted by the serous layer of the pericardium into the pericardial cavity. The pericardium consists of two layers, an outer fibrous layer and the ...

  6. Sternopericardial ligaments - Wikipedia

    en.wikipedia.org/wiki/Sternopericardial_ligaments

    The fibrous pericardium is attached to the posterior surface of the sternum by the superior and inferior sternopericardiac ligaments (sternopericardial ligaments); the upper passing to the manubrium, and the lower to the xiphoid process.

  7. Heart development - Wikipedia

    en.wikipedia.org/wiki/Heart_development

    Initially the tube remains attached to the dorsal part of the pericardial cavity by a mesodermal tissue fold called the dorsal mesoderm. This mesoderm disappears to form the two pericardial sinuses the transverse and the oblique pericardial sinuses, which connect both sides of the pericardial cavity. [7]

  8. Ascending aorta - Wikipedia

    en.wikipedia.org/wiki/Ascending_aorta

    The ascending aorta is covered at its commencement by the trunk of the pulmonary artery and the right auricula, and, higher up, is separated from the sternum by the pericardium, the right pleura, the anterior margin of the right lung, some loose areolar tissue, and the remains of the thymus; posteriorly, it rests upon the left atrium and right ...

  9. Henry Dalton - Wikipedia

    After tying the severed intercostal artery to control bleeding and removing the blood from the pleural cavity, Dalton observed a transverse wound of the pericardium about 2 inches (5 cm) in length. With a sharply curved needle and catgut , he closed the wound by continuous suture , overcoming great difficulty caused by the heart pulsations.
