De Novo Eosinophilic Myocarditis after Heart Transplantation

Eosinophilic myocarditis (EM) is a rare cause of cardiac arrest and cardiogenic shock. However, in the cardiac transplant population on immunosuppressive therapy this phenomenon has never been described. We report a case of a patient 3 years after heart transplantation who suffered a cardiac arrest and had allograft biventricular failure with histological evidence suggestive of EM.
