Abstract

Thrombus formation is a troublesome and sometimes lethal complication occurring in patients with severe heart failure and supported by a left ventricular assist device (LVAD). Appropriate treatment for pump thrombosis especially in emergency cases with severe pump failure is difficult to choose. Herein, we present important findings of a case of unexpected LVAD pump thrombosis that rapidly developed into serious pump failure and circulatory arrest due to total obstruction of the LVAD inflow tract by a huge thrombus.
