The ProtekDuo as Double Lumen Return Cannula in V?VP ECMO Configuration: A First?In?Man Method Description

We present a case of acute respiratory distress syndrome (ARDS) secondary to COVID?19 who required venovenous extracorporeal membrane oxygenation (V?V ECMO). Initially, a right ventricular assist device (RVAD), the ProtekDuo with an oxygenator, was placed in an outside heart center and the patient was transferred to us for ECMO management. Due to severe hypoxia, the configuration was later modified, and a 25 Fr femoral drainage cannula was inserted for venous drainage only. The arterial return tubing was spliced and using a Y?connector, arterialized blood was returned through both limbs of the ProtekDuo resulting in a significantly increased oxygenation and flow.
