Key result
Surgical management of an incidentally diagnosed pheochromocytoma in a 55-year-old woman resulted in positive outcomes and no further episodes of recurrent takotsubo cardiomyopathy.
Why the study?
Recurrent takotsubo cardiomyopathy is rare, and pheochromocytoma is an uncommon but important underlying secondary cause to consider.
Case Report (n=1)
Pheochromocytoma should be considered as a secondary cause in patients with recurrent takotsubo cardiomyopathy, even without resistant hypertension.

Supports considering pheochromocytoma in recurrent TC; leaves open whether systematic screening prevents recurrence.
Recurrent takotsubo cardiomyopathy (TC) is rare, with recurrence rates reported at 1%-6%. Pheochromocytoma, a catecholamine-secreting tumour, is an uncommon but important underlying cause. We present the case of a 55-year-old woman with 3 TC episodes, including both classical and atypical forms, leading to the incidental diagnosis of pheochromocytoma. Surgical management resulted in positive outcomes and no further TC events, emphasising the importance of considering secondary causes such as pheochromocytoma in recurrent TC, even in the absence of resistant hypertension.

Khadija et al. (2024) conducted a case report in Recurrent Takotsubo Cardiomyopathy and Pheochromocytoma (n=1). Surgical management was evaluated on Recurrence of takotsubo cardiomyopathy events. Surgical management of an incidentally diagnosed pheochromocytoma in a 55-year-old woman resulted in positive outcomes and no further episodes of recurrent takotsubo cardiomyopathy.
