Facilitated cardiac recovery in fulminant myocarditis: pediatric use of the Impella LP 5.0 pump

Abstract

We describe the successful use of the Impella LP 5.0 intracardiac microaxial pump (Abiomed, Danvers, MA) in a 13-year-old boy with fulminant biopsy-proven viral myocarditis. The patient, who previously was in refractory cardiogenic shock despite increasing inotropic and vasopressor support, immediately stabilized after Impella LP 5.0 implantation and was successfully bridged to a full recovery. Months later, he remains completely well, with no intracardiac or peripheral vascular sequelae of the procedure. In carefully selected pediatric patients the Impella may be a beneficial form of temporary mechanical circulatory support for fulminant cardiogenic shock.
