Veno-arterial extracorporeal membrane oxygenation for cardiogenic shock due to myocarditis in adult patients.

Myocarditis is an inflammatory disease of the heart muscle with established histological, immunological and immunohistochemical diagnostic criteria. Different triggers could be advocated as possible etiologies of myocarditis such as viral and non-viral infections, medications, systemic autoimmune diseases and toxic reactions. The spectrum of clinical presentations of myocarditis is broad and varies from subclinical asymptomatic courses to refractory cardiogenic shock. The prognosis of patients with myocarditis depends mainly on the severity of clinical presentation. In particular, myocarditis patients developing cardiogenic shock refractory to optimal maximal medical treatment may benefit from the use of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) as a temporary mechanical circulatory support (MCS). The aim of the present report is to offer a review of the most important articles of the literature showing the results of VA-ECMO in the specific setting of cardiogenic shock due to myocarditis in adult patients.
