Reverse takotsubo cardiomyopathy- life-threatening symptom of an incidental pheochromocytoma: a case report.

Background: 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.

Case summary: 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.

Discussion: 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.
