摘要：

The Impella 5.5 & REG; (Abiomed, Danvers, MA, USA) is a microaxial flow pump that promotes left ventricular unloading and improves end-organ perfusion before durable left ventricular assist device (LVAD) implantation. Thrombus formation after Impella 5.5 insertion can occur and represents a significant challenge to device explantation. Durable LVAD implantation is typically performed without aortic cross-clamping, so a dislodged thrombus can potentially embolize and lead to catastrophic events. We describe our technique to safely explant an Impella 5.5 in patients who develop a thrombus on the inflow portion of the device before surgical LVAD implantation. Visual abstract
