Advance in perinatal management of fetuses with abnormal cardiac physiological shunts / 中华围产医学杂志

ABSTRACT

Prior to birth, fetal pulmonary vessels are constricted and fetal lungs and liver are not fully functional. Ductus arteriosus, foramen ovale, and ductus venosus, which are unique cardiovascular structures of fetuses, constitute a parallel circulatory system. A comprehensive understanding of the outcomes of fetuses with abnormal cardiac physiological shunts and improving perinatal management are of great significance in reducing the risk of fetal and neonatal mortality. This review primarily describes the etiology, pathophysiology, treatment strategies, and prognosis of abnormal cardiac physiological shunts in fetuses.
