The fact that right heart failure is associated with low systemic perfusion pressures limits the systemic use of potent vasodilators in this patient population. As a consequence, no therapeutic recommendations exist for patients experiencing right heart failure in the course of PAH.Trade Name: Ventavis(Iloprost)
