Cardiogenic shock (CS) due to takotsubo cardiomyopathy (TTC) is a life-threatening condition. Therapy is challenging because of the ambivalent effects of catecholamines. Catecholamines are required to stabilize blood pressure but might aggravate TTC. Cardiac assist devices could be a suitable solution for conserving catecholamines and the prevention of TTC perpetuation.
We report the case of a male patient with refractory CS and severe respiratory insufficiency as a result of a reverse TTC, which involved both ventricles. Simultaneous circulatory support with an Impella CP and veno-arterial extracorporeal membrane oxygenation was initiated for cardiopulmonary stabilization and catecholamine weaning. A giant, incidental pheochromocytoma was diagnosed as the cause of TTC. After drug treatment and resection of the tumour, biventricular function completely recovered within 7 weeks.
A rare and challenging situation is the coincidence of a nor/epinephrine-secreting tumour, such as a pheochromocytoma, and severe CS complicating TTC. Although percutaneous left ventricular assist devices (pLVAD) are highly complicated and have shown conflicting results in terms of clinical efficacy for CS, its use may prevent the perpetuation of TTC due to reduced catecholamines requirement.
应激性心肌病(TTC)所致的心源性休克(CS)是一种危及生命的状况。由于儿茶酚胺的矛盾作用,治疗具有挑战性。需要儿茶酚胺来稳定血压,但可能会加重TTC。心脏辅助装置可能是保存儿茶酚胺和预防TTC持续的合适解决方案。
我们报告了一例男性患者,因反向型TTC累及双心室导致难治性CS和严重呼吸功能不全。为稳定心肺功能和减少儿茶酚胺用量,启动了Impella CP与静脉-动脉体外膜肺氧合同时进行循环支持。诊断出一个巨大的、偶然发现的嗜铬细胞瘤是TTC的病因。经过药物治疗和肿瘤切除后,双心室功能在7周内完全恢复。
一种罕见且具有挑战性的情况是,分泌去甲肾上腺素/肾上腺素的肿瘤,如嗜铬细胞瘤,与严重的CS并发TTC同时存在。尽管经皮左心室辅助装置(pLVAD)非常复杂,并且在CS的临床疗效方面显示出相互矛盾的结果,但其使用可能因减少儿茶酚胺需求而防止TTC持续。
