Abstract: Objective： To investigate the clinical presentation, diagnosis and treatment of the Eisenmenger’s syndrome in pregnancy.  Methods:  One case of Eisenmenger’s syndrome in pregnancy in our hospital was retrospectively analyzed and the literature reviewed.  Results: This patient who received antenatal care irregularly in other hospital was diagnosed with Eisenmenger’s syndrome with the symptoms of chest distress. The other hospital suggested her to terminate pregnancy, but the patient refused. She was admitted to our hospital in her late pregnancy, received the treatment of rest, oxygen, blood gas and pulmonary artery pressure monitoring. Considering perioperative pulmonary hypertension crisis likely to occur, pulmonary artery catheter was placed preoperatively. In general anesthesia, the cesarean was performed. After operation, the patient was transferred to the intensive care unit, with the treatment of expanding blood vessels, reducing pulmonary artery pressure, administering anticoagulation and preventing infection. One week later, the patient was discharged from hospital with smooth condition.  Conclusion:  Eisenmenger’s syndrome in pregnancy is associated with extremely poor maternal and fetal outcome. Termination of pregnancy should be offered to such patients. When interruption of pregnancy is refused, the early hospital admission is needed. The patients should be managed in a highrisk pregnancy unit by a multidisciplinary team from obstetrics, cardiology, anesthesia and pediatrics for improving pregnancy outcomes.
