Abstract
Left ventricular (LV) unloading is an important concept in patients undergoing peripheral venoarterial extracorporeal membrane oxygenation (VA-ECMO). We present a case of a 32-year-old male in acute cardiorespiratory collapse due to coronavirus disease (COVID-19) who underwent VA-ECMO cannulation in the setting of cardiogenic shock and acute respiratory distress syndrome. Due to inability to utilize percutaneous LV assist device (pLVAD) for LV unloading due to small end diastolic dimension, alternative strategies were explored. A traditionally utilized right ventricular support device, the ProTek Duo (TandemLife, Pittsburgh, PA), was utilized to drain the pulmonary artery, leading to improvement in parameters for cardiogenic shock. To our knowledge, this is the first case in which a ProTek Duo has been utilized in conjunction with VA-ECMO to provide LV unloading in support of a patient in cardiogenic shock. This method can be employed in future challenging situations where pLVAD is not feasible.
