Background:
Amniotic fluid embolism is a catastrophic illness related to the passage of fetal material into the pulmonary circulation causing cardiovascular collapse.
Case:
A 29-year-old female sustained cardiopulmonary arrest during delivery presumably due to amniotic fluid embolism. A right atrial mass "in transit" was detected by echocardiography. It had an appearance and pattern of motion that was suggestive of a gelatinous consistency and is likely to have been an amniotic fluid embolus. There was also evidence of acute right ventricular overload.
Conclusion:
We recommend that echocardiography be considered early on such conditions to gain more insight into the pathogenesis of this complication.
