Levosimendan. A promising future drug for refractory cardiac failure in children?

Intravenous positive inotropic agents play an important role in treating acute decompensation of patients with heart failure due to left ventricular systolic dysfunction. Levosimendan is a new positive inotropic agent having ATP-dependent potassium-channel opening, and calcium-sensitizing effects, which increases cardiac contractility and performance along with vasodilatatory action without increasing myocardial oxygen demand. We report a case of a 12-year-old girl with viral myocarditis, dilated cardiomyopathy, biventricular failure with severe left ventricular dysfunction, refractory to standard management, and who was successfully improved with levosimendan.
