Differences between intra-pump and outflow graft thrombosis [22].

	Intra Pump Thrombosis	Outflow Graft Thrombosis
Signs	Progressive exertional dyspnea	Signs of distal embolization
Duration	Short	Long
Hemolysis	Increased LDH, Low Hemoglobin, increased plasma free hemoglobin, dark urine	Absent
Echocardiographic findings	Inflow cannula turbulence with visible thrombus	Outflow cannula turbulence and no visible thrombus inside the LV
CT angiography	No outflow graft obstruction	Outflow graft stenosis, obstruction
LVAD parameters	Low flow alarm and decrease in power spikes
