Extracorporeal life support (ECLS) may serve as an effective bridge to recovery in patients with Takotsubo cardiomyopathy complicated by refractory cardiogenic shock.
May support ECLS in refractory Takotsubo shock; hypothesis-generating and should not change practice.
Takotsubo cardiomyopathy (TC) is characterized by the sudden onset of reversible left ventricular dysfunction, with a presentation similar to that of an acute coronary syndrome. Although cardiogenic shock is a rare occurrence in TC, if it does occur it may require the use of a left ventricular assist device. We report the use of extracorporeal life support (ECLS) in a patient with TC and refractory cardiogenic shock. With ECLS it was possible to reduce inotropic support, and a normal left ventricular ejection fraction was documented by echocardiography on day 2. This is, to our knowledge, the first reported case of TC with refractory cardiogenic shock treated with ECLS in Portugal. A miocardiopatia de Takotsubo (MT) é caracterizada por uma disfunção ventricular esquerda súbita, tendo uma apresentação semelhante à de uma síndrome coronária aguda. Apesar do choque cardiogénico ser uma ocorrência rara na MT, caso ocorra, pode levar ao uso de dispositivos de assistência ventricular esquerda. Reportamos o caso de uma doente com MT e choque cardiogénico onde foi utilizado suporte de vida extracorporal (SVEC). Com o SVEC foi possível reduzir o suporte aminérgico e documentada em ecocardiografia uma fração de ejeção normal ao 2.° dia. No conhecimento dos autores este é o primeiro caso, em Portugal, de choque cardiogénico por MT em que é usado o SVEC como ponte para a melhoria.

Silva et al. (2015) conducted a case report in Takotsubo cardiomyopathy with refractory cardiogenic shock (n=1). Extracorporeal life support (ECLS) was evaluated on Reduction in inotropic support and normalization of left ventricular ejection fraction. Extracorporeal life support successfully reduced inotropic support and normalized left ventricular ejection fraction by day 2 in a patient with Takotsubo cardiomyopathy and cardiogenic shock.
