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.
摘要：
Takotsubo心肌病（TTC），也被称为应激性心肌病或心碎综合征，是一种以一过性左心室功能障碍为特征的疾病，类似于心肌梗塞，但没有阻塞性冠状动脉疾病。我们介绍了一例罕见的病例，该病例是由未诊断的右肾上腺嗜铬细胞瘤肿瘤引发的反向TTC引起的心源性休克（CS）。患者最初表现为慢性头痛和呼吸困难，他们的病情迅速恶化，需要插管和正性肌力支持。诊断测试证实了反向TTC的诊断，进一步的调查显示，肾上腺肿块活跃增长，提示嗜铬细胞瘤。患者对治疗反应良好，包括使用主动脉内球囊泵支持和随后的断奶。右肾上腺切除术证实存在嗜铬细胞瘤。这个案例突出了嗜铬细胞瘤和反向TTC之间的关联，强调在出现CS的患者中需要考虑这种罕见的病因。由于复发的风险，长期监测至关重要，甚至在肿瘤切除后.
