Pheochromocytoma is a potentially overlooked trigger of Takotsubo syndrome that may present without overt stressors and can be associated with chemical myocarditis and severe complications.
Pheochromocytoma should be considered as a potential trigger for Takotsubo syndrome, particularly in patients presenting with atypical demographics, absence of overt stressors, and signs of extreme adrenergic discharge.
In clinical practice, pathophysiology of Takotsubo syndrome (TTS) has been attributed to adrenergic discharge mostly associated with a variety of stressors. Occasionally, organic sources of adrenergic discharge (including pheochromocytoma) might also account for this phenomenon and are not considered as exclusion criteria for the diagnosis of TTS (as opposed to previous suggestions). We read with great interest the recently published article by Maffè et al. that describes a case of fatal TTS due to a ruptured pheochromocytoma in a middle-aged male. In this context, we would like to comment on this interesting case and potential implications of TTS associated with pheochromocytoma....

Yalta et al. (2021) conducted a letter in Takotsubo syndrome associated with pheochromocytoma. Pheochromocytoma was evaluated. Pheochromocytoma is a potentially overlooked trigger of Takotsubo syndrome that may present without overt stressors and can be associated with chemical myocarditis and severe complications.
