| Summary: | Pulmonary arterial hypertension is a pernicious disease with a diverse etiology in the pediatric population. Despite the increased availability of drug therapies, pulmonary arterial hypertension continues to cause significant morbidity and mortality. In pediatric patients with severe pulmonary arterial hypertension who have failed medical therapy, a few studies have demonstrated the role of balloon atrial septostomy as a bridge to lung transplantation or a means of improving symptomatology. However, no data exists on the utilization of balloon atrial septostomy as a palliative intervention to wean from extracorporeal membrane oxygenation (ECMO) when all other therapies are exhausted. Here we describe a case series of two pediatric patients with severe pulmonary arterial hypertension, requiring ECMO support, who were successfully weaned from ECMO following balloon atrial septostomy.
