Pericardial Disorders
Pericardial can refer to: * Pericardial sinus * Pericardium * Pericardial effusion A pericardial effusion is an abnormal accumulation of fluid in the pericardial cavity. The pericardium is a two-part membrane surrounding the heart: the outer fibrous connective membrane and an inner two-layered serous membrane. The two layers of t ... {{disambig ...

Pericardial Sinus
The pericardial sinuses are impressions in the pericardial sac formed between the points where great vessels enter it. Structure There are three pericardial sinuses: superior, transverse and oblique. * The superior sinus is anterior to the ascending aorta and the pulmonary trunk. It cannot be assessed in electrophysiology procedures. * The oblique sinus is an inverted J-shaped reflection of the venae cavae and pulmonary veins. It lies behind the atria (particularly the left atrium), and in between left and right pulmonary veins. * The transverse sinus is the tunnel-shaped passage posterior to the aorta and pulmonary trunk , and anterior to the superior vena cava. This sinus is clinically important because passing one end of clamp through the sinus, and the other end anterior to the aorta/pulmonary trunk will allow complete blockage of blood output. This is performed during some heart surgeries. Clinical significance During pericardial effusion, fluid In physics, a flui ...

Pericardium
The pericardium, also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. It has two layers, an outer layer made of strong connective tissue (fibrous pericardium), and an inner layer made of serous membrane (serous pericardium). It encloses the pericardial cavity, which contains pericardial fluid, and defines the middle mediastinum. It separates the heart from interference of other structures, protects it against infection and blunt trauma, and lubricates the heart's movements. The English name originates from the Ancient Greek prefix "''peri-''" (περί; "around") and the suffix "''-cardion''" (κάρδιον; "heart"). Anatomy The pericardium is a tough fibroelastic sac which covers the heart from all sides except at the cardiac root (where the great vessels join the heart) and the bottom (where only the serous pericardium exists to cover the upper surface of the central tendon of diaphragm).
