Adrenal pheochromocytoma presenting with Takotsubo-pattern cardiomyopathy and acute heart failure

BACKGROUND Pheochromocytoma is an endocrine tumor that causes hypertension, facial pallor, and headache. Pheochromocytoma patients rarely present with acute heart failure or cardiogenic shock. METHOD We discuss the case of a female patient with Takotsubo-pattern cardiomyopathy who presented with acute heart failure caused by pheochromocytoma. RESULT Treatment was adjusted based on the data of the pulse contour cardiac output system. After intensive hydration and medication for heart failure, the condition of the patient stabilized. CONCLUSION Before confirming the diagnosis, pulse contour cardiac output data could provide a direction for diagnosis and treatment.
