An unusual case of peripartum cardiomyopathy in a parturient with preeclampsia.

Here we report an unusual development of peripartum cardiomyopathy (PPCM) in a parturient woman with preeclampsia. A 36-year-old nulliparous parturient woman underwent elective cesarean section for delivery of twins under spinal anesthesia. Both preoperative workup and past history were unremarkable except for proteinuria and hypertension for 1 week. Approximately 4 hours after cesarean section, progressive orthopnea developed. Chest plain film showed acute pulmonary edema, bilateral pulmonary infiltration with interstitial patches, and cardiomegaly. Postpartum cardiomyopathy was diagnosed afterward by echocardiography. This showed general hypokinesia and severe dysfunction of the left ventricle with ejection fraction of 15-20%. She was admitted to the intensive care unit for further management. Fortunately, the patient recovered after treatment and was discharged 15 days later. This case illustrates that we should bear in mind the possibility of PPCM if orthopnea develops while delivery is approaching in a parturient with preeclampsia. Echocardiography is helpful for early diagnosis of PPCM.
