Is fetal pericardial effusion detected on four-dimensional ultrasound a cause for concern?

This condition is considered normal. Pericardial effusion in pregnant women may result from factors such as maternal constitutional weakness or intra-amniotic infection. If the fetal pericardial effusion is minimal and no other severe symptoms are present, specific treatment is generally unnecessary. However, if pericardial effusion in a newborn is severe, surgical intervention may be required. Regular follow-up examinations are recommended. Should the pregnancy extend beyond term and the pericardial effusion progressively increase, treatment under the guidance of a physician is advised.
