As a bridge to heart transplantation or destination treatment, implantation of the Heartmate 3 (HM3) left ventricular assist device is a viable option for patients with end-stage congestive heart failure. The recent Momentum 3 trial has shown favorable outcomes compared with Heartmate 2. We report the first case of aortic root thrombus occurring early after HM3 implantation as a bridge to heart transplantation. Our case suggests that bridging with an Impella 5.0 preceding HM3 implantation could

... potentially predispose patients to aortic root thrombus after HM3 implantation, due to Impella-related injury to the aortic valve and aortic root stasis after durable LVAD support.
