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.
左心室(LV)卸载是接受外周动静体外膜肺氧合(VA-ECMO)治疗的患者的一个重要概念。我们报告了一例因冠状病毒病(COVID-19)导致急性心肺衰竭的 32 岁男性患者,在心力衰竭合并急性呼吸窘迫综合征的情况下进行了 VA-ECMO 插管。由于小舒张末期内径导致无法使用经皮左心室辅助装置(pLVAD)进行 LV 卸载,因此探索了替代策略。传统上使用的右心室支持装置,ProTek Duo(TandemLife,匹兹堡,PA),被用于引流肺动脉,导致心源性休克的参数得到改善。据我们所知,这是首例将 ProTek Duo 与 VA-ECMO 联合用于支持心源性休克患者的 LV 卸载的病例。在未来无法使用 pLVAD 的具有挑战性的情况下,可以采用这种方法。
