Aortic root thrombosis after HeartWare implantation

A 41-year-old patient presented in cardiogenic shock. After hemodynamic stabilization, a HeartWare assist device was implanted. However, a postoperative echocardiographic examination revealed thrombus formation in the aortic root (Figure 1). After multidisciplinary discussion, the HeartWare flow was increased to avoid opening of the aortic valve, and successfully prevented embolization. The patient is currently on the urgent waiting list for a donor heart.
