Adrenal pheochromocytoma presenting with Takotsubo-pattern cardiomyopathy and acute heart failure: A case report and literature review.

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.
