Use of the Prostacyclin-Receptor Agonist Selexipag in Pulmonary Arterial Hypertension Associated with Eisenmenger Syndrome

Eisenmenger syndrome is a multisystem disorder and the most severe form of Pulmonary Arterial Hypertension in adult Congenital Heart Disease. Pulmonary Arterial Hypertension represents a fatal disease, characterized by increased pulmonary vascular resistance, right heart failure and death. Although therapeutic management has rapidly advanced in recent years, these patients were not included in randomized controlled trials for specific Pulmonary Arterial Hypertension drugs, except for Bosentan. However, in clinical practice we apply treatment strategies combining drugs targeting multiple pathobiological pathways. We present three patients with Eisenmenger syndrome and their improvement after initiation of Selexipag, an oral selective IP prostacyclin-receptor agonist.
