[Catecholamine Cardiomyopathy Presenting Inverted-takotsubo Pattern Asynergy].

Pheochromocytoma is complicated with catecholamine cardiomyopathy, and preoperative care becomes considerably more difficult We report anesthetic management for an 48-year-old man brought to our hospital by ambulance and immediately hospitalized due to pheochromocytoma crisis complicated with catechol- amine cardiomyopathy presenting inverted-takotsubo pattern asynergy. Before surgery, α and β blocking drugs were used to control hypertension and tachycardia, and continuous hemodiafiltration was initiated and the patient was intubated for severe pulmonary edema. Seven days later, he underwent laparoscopic adrenalectomy. Total intravenous anesthesia was achieved with propofol, remifentanil, fentanyl, and rocuronium. During the operation, continuous infusion of landiolol, phentolamine, and nitroglycerin, and addi- tional bolus injections of landiolol were given to control hypertension. After severing the right adrenal vein, noradrenaline (0.15 μg · kg⁻¹ · min⁻¹), and dopamine (4μg · kg⁻¹ · min⁻¹) were started and the patient was placed in the intensive care unit Inverted-takotsubo pattern asynergy is not very common, and treatment consists of supportive care, as in the usual takotsubo. Preoperative CHDF (continuous hemodiafiltration) may be useful when it is difficult to control hypertension or tachycardia with medications.
