Veno-venous extracorporeal membrane oxygenation bridging to pharmacotherapy in pulmonary arterial hypertensive crisis

Abstract

We report the case of a treatment-naive patient with pulmonary arterial hypertension who presented with decompensated right ventricular failure and cardiogenic shock. Unstable hemodynamics, hypoxia and end-organ hypoperfusion limited up-titration of pharmacotherapy. Mechanical circulatory support with veno-venous extracorporeal membrane oxygenation (VV-ECMO) was initiated to permit dose titration of pulmonary vasodilator therapy. VV-ECMO was weaned after 10 days of support, with successful transition to intravenous epoprostenol and oral sildenafil.
