The Effect of Inhaled Milrinone Versus Inhaled Levosimendan in Pulmonary Hypertension Patients Undergoing Mitral Valve Surgery - A Pilot Randomized Double-Blind Study

Because inhaled levosimendan causes a decrease in PASP and MPAP without causing a decrease in SVR and MAP, the authors conclude that inhaled levosimendan is a selective pulmonary vasodilator. It is as effective as milrinone in reducing pulmonary artery pressures. In addition, it has advantage over inhaled milrinone because it is has a longer duration of action.
