Pericardial aspiration is used in patients with pericardial effusion, which affects heart function. This technique will help aspirate pericardial fluid so that the heart can resume functioning, avoiding continued accumulation of fluid in the pericardial capsule.

The pericardium is a protective sac that contains a small amount of lubricant, which limits the movement of the heart in the ribcage and protects the heart from mechanical injury or infection from nearby areas.

Pericardial fluid is a fluid located between the two layers of the pericardium, the parietal and visceral leaves. Fluid has a lubricating function and helps the heart work more smoothly and easily. When the amount of fluid is abnormally high or invaded by bacteria, it will cause diseases and syndromes such as pericardial effusion, acute pericarditis, etc.

Prenatal ultrasound determination of a pericardial effusion less than 2 mm thick is a normal finding. However, if the fetal pericardial effusion is 2 mm or more thick, it may be related to cardiac structural abnormalities or congenital diseases.

Pericardial calcification is one of the common problems in patients with constrictive pericarditis. Early diagnosis of pericardial calcification through methods such as ultrasound, X-ray,... brings great value to effective treatment of the disease.

Pericardiocentesis is used in cases where the patient has pericardial effusion, which affects the heart function. This technique will help to drain the pericardial fluid so that the heart can restore its function, avoiding further accumulation of fluid in the pericardial sac.
