Background:
The implantation of mechanical ventricular support devices has become a standard therapeutic approach for selected patients with advanced heart failure. Aortic root thrombosis after temporary left ventricular assist device (LVAD) support represents an uncommon complication, with inconclusive optimal management strategies.
Case Summary:
A patient presented with refractory heart failure. After the implantation of temporary LVAD support, an aortic root thrombus developed. During an intensification of unfractionated heparin treatment, the aortic thrombus eventually dissolved; however, this dissolution was accompanied by embolic events in the spleen and both kidneys, and cardiac tamponade. Subsequently, the patient received a long-term HeartMate 3 LVAD.
Discussion:
Aortic root thrombus poses significant management challenges. Preventive strategies, including ensuring partial aortic valve opening and proper implantation of LVAD, are essential.
Take-Home Messages:
It is important to be aware of the potential occurrence of early aortic root thrombus formation after temporary LVAD implantation. Prevention strategies are crucial to minimize the risk of thrombosis.
