Relapse of giant cell myocarditis supported with veno-arterial extracorporeal membrane oxygenation.

Giant cell myocarditis (GCM) is a fatal form of myocarditis that often presents with acute heart failure. An inflammatory infiltrate with giant cells and myocardial necrosis is characteristic. During the acute presentation, mechanical circulatory support may be necessary for hemodynamic support while immunosuppression is initiated. We report a case of GCM relapse which was supported with veno-arterial membrane oxygenation until recovery. The patient is doing well one year after explantation.
