[Bridge to recovery with ventricular assist device support for eosinophilic myocarditis]

A 39-year-old man initially presented with cough, fever, and shortness of breath. His symptom got worse gradually, and he was admitted to a nearby hospital. Echocardiography revealed a dilated left ventricle and severe left ventricular dysfunction. Despite inotropic and intra-aortic balloon pumping (IABP) support, the patient developed cardiogenic shock with fever of unknown origin, followed by multi-organ failure. A left-ventricular assist device (LVAD) was implanted. Pathologic evaluation showed an extensive eosinophil-rich inflammatory infiltrate, and consistent with the diagnosis of eosinophilic myocarditis. After high-dose steroid administration, the cardiac function improved and explantation of the LVAD was successfully performed. The patient was discharged and remains well at the 24-month follow-up.
