The heart is covered with a thin membrane, medically known as the pericardium. It has two types of serous pericardium and fibrous pericardium, and the serous pericardium is divided into two layers: a layer which tightly covers the surface of the heart and is the pericardium of the heart; the other layer is outside the visceral layer and is the pericardium. There is a cavity between the pericardium and the parietal layer, called pericardial cavity. The pericardium is covered by a tough fibrous pericardium, which is transformed upwards into the great vessel adventitia to enter and exit the heart, and fixed downwards to the central tendon of the diaphragm, so that the heart is stably positioned in the normal position of the chest. The pericardium itself or the general disease causes the pericardium to secrete too much liquid, and the liquid is accumulated in the pericardium cavity, and the pericardium exceeds the normal range to cause corresponding clinical symptoms and signs, which are called pericardial effusion. Pericardial effusion can be drained by pericardiocentesis, and medicaments should be infused to treat pericardial inflammation after drainage.
