Pathophysiology[edit | edit source]

  • In pericardial effusion, there is extra fluid collects between the heart and the pericardium (the sac around the heart).
  • The extra fluid causes pressure on the heart.
  • This keeps it from pumping blood normally.
  • Lymph vessels may also be blocked, which can cause infection.

Causes[edit | edit source]

Pericardial effusions may be caused by cancer or cancer treatment, infection, injury, autoimmune disorders, thyroid disease or kidney problems etc.

Symptoms[edit | edit source]

Symptoms of pericardial effusion include chest pain, rapid heartbeat, and difficulty breathing. Fever is a common symptom of acute pericarditis.

Diagnosis[edit | edit source]

Diagnosis was with physical exam, imaging tests, and heart tests such as echocardiography to make a diagnosis.

Treatment[edit | edit source]

Treatment depends on the cause and may involve pericardiocentesis

Complications[edit | edit source]

If the pericardial effusion is severe, it can lead to a life threatening emergency called cardiac tamponade where the heart is compressed due to pressure of the fluid in the pericardial sac. Immediate medical attention is required in thi case.
