Background: Inverted Takotsubo’s cardiomyopathy requiring extra-corporeal membrane support (ECMO) with pheochromocytoma is well described. Classic Takotsubo’s cardiomyopathy, however, is rarely described in this setting. Clinical Case: A 50-year old woman with no previous comorbidities presented with pulmonary edema and cardiogenic shock. She required rapid escalation of vasopressor, inotrope, and intra-aortic balloon pump then ECMO with consideration of cardiac transplant. Initial echocardiogram showed an ejection fraction of 17%. Coronary angiography showed apical ballooning in keeping with classic Takotsubo’s cardiomyopathy. Abdominal ultrasound for transplant screening showed a 4.6 cm abdominal mass. Computed tomography confirmed a 4.6 cm mass with classic radiologic features of pheochromocytoma. Plasma free normetaphrine and metanephrine were elevated at 2.34 nmol/L and 0.25 nmol/L. A 24-hour urine collection included urine volume of 3500 ml, urine creatinine 7.2 mmol/day, elevated urine norepinephrine 1199 nmol/day, elevated urine epinephrine 888 nmol/day, and normal urine dopamine 335 nmol/day. Parathyroid hormone and calcitonin were normal at 0.4 pmol/L and 4.8 pmol/L, respectively. Plasma aldosterone was normal at 87 pmol/L and plasma renin normal at 3.5 ng/L. Doxazosin 1 mg daily was initiated and she had clinical improvement next day and came off ECMO. Her ejection fraction improved to 55% subsequent week. She had retroperitoneoscopic adrenalectomy two weeks later with full recovery. Conclusion: Classic Takotsubo’s cardiomyopathy is a possible presentation of pheochromocytoma with rapid resolution with alpha blockade.
