Case Reports
[Levosimendan treatment of severe acute congestive heart failure refractory to dobutamine/milrinone in children].
Levosimendan is a novel positive inotropic agent which, improves myocardial contractility through its calcium-sensitizing action, without causing an increase in myocardial oxygen demand. Also, by opening ATP-sensitive potassium channels, it causes vasodilatation with the reduction in both afterload and preload. Because of the long half-life, its effects last for up 7 to 9 days after 24-hour infusion. ⋯ Our initial experience demonstrates that administration of levosimendan in patients with severe chronic heart failure not responsive to standard intravenous inotropic treatment might result in a significant clinical and hemodynamic improvement and that, in selected patients, it might be life saving. According to our best knowledge patients presented are the first pediatric patients treated with levosimendan in our country.
