Introduction and importance Women with Eisenmenger syndrome are usually advised to avoid pregnancy because of the high maternal mortality rate of 30–50% which increases up to 65% in the case of a cesarean section. Successful management of Eisenmenger syndrome in pregnancy is tricky and has a narrow margin of safety; however, carefully coordinated multidisciplinary care can profoundly optimize the chances of survival for both mother and baby. Case presentation A 28-year-old, 24-week-pregnant patient with a non-corrective ventricular septal defect (VSD) was diagnosed with Eisenmenger syndrome but elected to continue her pregnancy despite the high risks on her and her fetus. Therefore, a multidisciplinary team was assembled to fully monitor the patient and ensure that she reaches 32 weeks before delivery. Clinical discussion Multiple scenarios for timing and mode of delivery were discussed. Following the recommendation of the 2018 European Society of Cardiology guidelines and because of the fetus’ transverse position, a cesarean section was performed at week 32 and both the patient and her child were saved. Conclusion Termination of pregnancy is the safer option only if it were done early on in the pregnancy. Thus, when the pregnancy is continued, an expert multidisciplinary team is put together to support the patient.
