Fulminant immune checkpoint inhibitor-associated myocarditis bridged to recovery with a temporary left ventricular assist device: a case report

Early recognition of ICI-associated myocarditis can be achieved with biochemical testing, electrocardiography, imaging, and expedited investigation of alternative causes for cardiac decompensation. Our case demonstrates that temporary left ventricular assist devices can support cardiac output for patients in cardiogenic shock due to ICI-associated myocarditis, allowing for recovery following high-dose corticosteroids.
