Abstract

A patient presented with a decompensated cardiomyopathy requiring invasive hemodynamic support with an Impella® heart pump. Extracorporeal life support (ECLS) became necessary during the further course and the patient was bridged to left ventricular assist device (LVAD) implantation. Postoperatively, the patient did not improve as expected due to new aortic regurgitation (AR) that was most likely caused by the previously placed Impella. A SAPIEN 3 transcatheter aortic valve was implanted as a bail-out strategy; an additional valve-in-valve rescue was required due to paravalvular regurgitation. This resulted in a restitution of valvular function and hemodynamic improvement. TAVI appears to be a valuable bail-out option for postoperative AR following LVAD implantation.

术前Impella®支持下左心室辅助装置植入后主动脉瓣返流的抢救TAVI。
患者表现为失代偿性心肌病,需要使用Impella®心脏泵进行侵入性血流动力学支持。在进一步的过程中,体外生命支持(ECLS)成为必要,患者被桥接至左心室辅助装置(LVAD)植入。术后,由于新的主动脉反流(AR),患者没有像预期的那样改善,这很可能是由先前放置的Impella引起的。经导管植入SAPIEN 3型主动脉瓣作为救助策略;由于瓣旁反流,需要进行额外的阀中抢救。这导致了瓣膜功能的恢复和血流动力学的改善。TAVI似乎是LVAD植入后术后AR的一个有价值的救助选择。
