Abstract
Fulminant necrotizing eosinophilic myocarditis (FNEM) is a rare form of EM characterized by biventricular heart failure with hemodynamic deterioration, often requiring inotropes or mechanical circulatory support. Here, we report a case of a 43-year-old healthy woman with FNEM who was admitted with acute heart failure that rapidly progressed to cardiogenic shock and electrical storm, culminating in cardiac arrest. Early diagnosis and prompt administration of corticosteroids in combination with veno-arterial extracorporeal membrane oxygenation allowed complete recovery of biventricular systolic function.
