Moderate or severe aortic insufficiency is a contraindication to transvalvular Impella left ventricular assist device (Abiomed) use out of concern for worsening valvular insufficiency and recirculation. This report describes the case of a 75-year-old man with severe eccentric aortic insufficiency and systemic hypoperfusion who was supported with a transvalvular Impella 5.5 device for 6 days as preoperative rehabilitation before aortic valve replacement. The Impella device provided adequate systemic tissue perfusion, and left ventricular function remained without signs of volume overload and recirculation. Moderate or severe aortic insufficiency may not be an absolute contraindication to transvalvular Impella use, although this is case dependent.
由于担心瓣膜关闭不全和再循环恶化，中重度主动脉瓣关闭不全是经瓣膜使用Impella左心室辅助装置（Abiomed）的禁忌症。本报告描述了一名75岁男性，患有严重的偏心性主动脉瓣关闭不全和全身灌注不足，在进行主动脉瓣置换术前，使用经瓣膜Impella 5.5装置进行了6天的术前康复治疗。Impella装置提供了足够的全身组织灌注，左心室功能保持无容量超负荷和再循环迹象。中重度主动脉瓣关闭不全可能不是经瓣膜使用Impella的绝对禁忌症，尽管这取决于具体病例。
