Pheochromocytoma is a group of rare tumors produce catecholamines. Clinical manifestations are mainly hypertension, headache, sweating, and palpitation. Cardiogenic shock rarely appears as the first manifestation of pheochromocytoma. A pregnant patient of 31⁺³ weeks was admitted to our hospital recently with cardiogenic shock as the first clinical manifestation. Initial diagnosis was considered as acute myocarditis and veno-arterial extracorporeal membrane oxygenation (VA-ECMO) was started. Her cardiac function rapidly improved, however, cardiogenic shock occurred again during ECMO withdrawal, and VA-ECMO was started again. Though abdominal CT examination and 24 hour urine and plasma methoxyepinephrine substances (MNs), diagnosis of pheochromocytoma with catecholamine cardiomyopathy was confirmed. With ECMO assistance, adrenal pheochromocytoma was removed with surgery. The patient was successfully evacuated from ECMO on the surgery day, discharged successfully after 9 days. The authors summarized the treatments in this case and reviewed related case reports, which could provide reference to treat pheochromocytoma catecholamine cardiomyopathy.
