Pericardial effusion is a condition in which a large amount of fluid is present in the pericardial cavity. At this time, if not detected in time or the rate of fluid formation is too fast, it can easily lead to acute cardiac tamponade, causing hemodynamic disturbances, ranging from cardiovascular collapse, mild hypotension to severe cardiogenic shock or death. Therefore, early diagnosis and active intervention are essential to help ensure the patient's life.

Normally, the pericardial cavity has only a very thin layer of fluid, which reduces friction and makes the heart easy to contract. If for some reason too much fluid accumulates, it is called a pericardial effusion. This condition is very easy to lead to acute cardiac tamponade, resulting in hemodynamic disturbances, ranging from vascular collapse, mild hypotension to severe cardiogenic shock, and death if not handled promptly.

Pericarditis is a cardiovascular disease in which the pericardium becomes inflamed and may be accompanied by effusion. The pericardium is a thin fibrous sheath that surrounds the heart, holds the heart in place in the ribcage and lubricates the heart.

Acute cardiac tamponade is an acute condition in which the heart is compressed due to the accumulation of fluid (or blood, pus) in the pericardial cavity, causing hemodynamic consequences ranging from mild cardiovascular collapse to severe cardiogenic shock and death. death if not treated promptly.

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.

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.

Angioplasty is a technique indicated for the treatment of pulmonary valve stenosis. This method is highly effective and successful, reducing the risk of unwanted complications.

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.

Cardiac tamponade is a clinical syndrome caused by a rapid increase in fluid in the pericardial cavity. This is an emergency.
