<unk>  (PT) is considered a specific case of a major device malfunction, and is classified as either suspected or confirmed<unk>  thrombus. Typically, the device is an implanted blood<unk>  such as a Left ventricular assist device. The malfunction is a blockage in the flow of blood anywhere along a vessel (upstream or downstream) and it is mainly due to the bio-incompatible presence of a fairly complex mechanical apparatus.<unk>  thrombus is dreaded complication of CF LVAD technology that can require repeat surgery to replace the<unk>  or lead to death. In suspected<unk>  thrombus, the clinical patient condition or<unk>  parameters suggest thrombus on any of the blood-contacting surfaces of the<unk>  (inflow cannula,<unk>  itself, or outflow graft). Confirmed<unk>  thrombus is done by visual inspection (during device exchange, transplantation, autopsy), irrefutable radiographic evidence, or absence of Doppler inflow or outflow signals.
