Maternal Mirror Syndrome Masquerading as Congestive Heart Failure: A Case Report.

Mirror syndrome is a rare pregnancy complication, life-threatening to mother and fetus. Increasing survival rates of congenital heart disease into reproductive age mean that complications like Mirror syndrome in this population may be more challenging to diagnose, given overlapping signs of edema in cases of heart failure exacerbation. We report a case of a pregnant woman with a history of unspecified congenital heart disease, presenting with swelling and distension, with diagnostic findings not consistent with preeclampsia. Her course was complicated by dyspnea, oliguria, and fetal hydrops. A cesarean delivery under neuraxial anesthesia was performed. We review the clinical manifestations of Mirror syndrome and discuss anesthetic and obstetric management considerations for this condition.
