Conventional venoarterial extracorporeal membrane oxygenation (VA-ECMO) places a functional afterload burden on the left ventricle. In the setting of acute severe aortic insufficiency-induced cardiogenic shock, the utility of VA-ECMO in combination with a failing valve may result in catastrophic haemodynamic consequences. This challenge is compounded when the culprit is a failing surgical bioprosthetic valve. We present a case of severe rapid-onset bioprosthetic aortic insufficiency-induced cardiogenic shock successfully resuscitated with left atrial VA-ECMO promptly followed by emergent percutaneous valve-in-valve transaortic valve replacement. We discuss the logistics, implications, and associated haemodynamic manifestations in utilizing this strategy for such disease processes.
传统的静脉-动脉体外膜肺氧合(VA-ECMO)会给左心室带来功能性后负荷。在急性严重主动脉瓣关闭不全引起的心源性休克的情况下,VA-ECMO 与功能衰竭的瓣膜联合使用可能会导致灾难性的血液动力学后果。当罪魁祸首是功能衰竭的外科生物瓣时,这一挑战更加复杂。我们报告了一例严重的快速发作的生物瓣主动脉瓣关闭不全引起的心源性休克病例,该病例通过左心房 VA-ECMO 迅速复苏,随后紧急经皮瓣中瓣经主动脉瓣置换术。我们讨论了在这种疾病过程中使用这种策略的逻辑、影响和相关的血液动力学表现。
