{Reference Type}: Case Reports {Title}: Reverse Takotsubo Cardiomyopathy Triggered by Undiagnosed Right Adrenal Pheochromocytoma: A Rare Occurrence. {Author}: Ahmad H;Jannat H;Khan U;Ahmad N; {Journal}: Cureus {Volume}: 15 {Issue}: 6 {Year}: 2023 Jun 暂无{DOI}: 10.7759/cureus.40924 {Abstract}: Takotsubo cardiomyopathy (TTC), also known as stress cardiomyopathy or broken heart syndrome, is a condition characterized by transient left ventricular dysfunction resembling myocardial infarction but without obstructive coronary artery disease. We present a rare case of a 59-year-old patient with cardiogenic shock (CS) caused by reverse TTC triggered by an undiagnosed right adrenal pheochromocytoma tumor. The patient initially presented with chronic headaches and difficulty breathing, and their condition rapidly deteriorated, necessitating intubation and inotropic support. Diagnostic tests confirmed the diagnosis of reverse TTC, and further investigation revealed an actively growing adrenal mass suggestive of a pheochromocytoma. The patient responded well to treatments, including the use of intra-aortic balloon pump support and subsequent weaning. A right adrenalectomy confirmed the presence of a pheochromocytoma. This case highlights the association between pheochromocytoma and reverse TTC, emphasizing the need to consider this rare etiology in patients presenting with CS. Long-term monitoring is crucial due to the risk of recurrence, even after tumor removal.
