Key result
A 50-year-old man with cardiogenic shock and reverse Takotsubo cardiomyopathy secondary to pheochromocytoma experienced LVEF recovery to 73% and was successfully treated with right adrenalectomy.
Why the study?
Acute catecholamine-mediated cardiomyopathy secondary to pheochromocytoma is rare but life-threatening.
Case Report (n=1)
Highlights the importance of considering pheochromocytoma-induced catecholamine cardiomyopathy in patients presenting with acute coronary syndrome-like symptoms and reverse Takotsubo pattern.
Pheochromocytoma may cause STEMI mimics without coronary occlusion; leaves open need for systematic screening studies.
Pheochromocytoma is a rare catecholamine-secreting neuroendocrine tumor arising from chromaffin cells. Acute catecholamine-mediated cardiomyopathy secondary to pheochromocytoma is rare, but life-threatening. We report a case of a 50-year-old man who presented with chest pain with electrocardiography showing ST elevation in V2-4. He was transferred to cardiac catheterization laboratory for coronary angiography immediately. However, the results showed no evidence of coronary artery occlusions and the left ventriculography revealed hypokinesia of basal part with poor left ventricular ejection fraction. Further investigation confirmed pheochromocytoma-related reversible cardiomyopathy.

Trongtorsak et al. (2021) conducted a case report in Cardiogenic shock with reverse Takotsubo pattern secondary to pheochromocytoma (n=1). Right adrenalectomy was evaluated on Left ventricular ejection fraction (LVEF) recovery. A 50-year-old man with cardiogenic shock and reverse Takotsubo cardiomyopathy secondary to pheochromocytoma experienced LVEF recovery to 73% and was successfully treated with right adrenalectomy.
