Heart transplantation under mechanical circulatory support for fulminant myocarditis: a Case Report.

Fulminant myocarditis has been defined as the clinical manifestation of cardiac inflammation with rapid-onset heart failure and cardiogenic shock. We report on the case of a 17-year-old boy with hemodynamic derangement and cardiac arrest due to fulminant myocarditis. After about 2 h of intensive cardiopulmonary resuscitation, with 13 days of extracorporeal membrane oxygenation support, the patient finally bridged to orthotopic heart transplantation. The patient recovered uneventfully and was discharged 37 days after transplantation. The explanted heart revealed diffuse lymphocytic infiltration and myocyte necrosis in all four cardiac chamber walls confirming the diagnosis and identifying the underlying cause of fulminant myocarditis.
