Differences in von Willebrand factor function in type 2A von Willebrand disease and left ventricular assist device‐induced acquired von Willebrand syndrome

Patients with von Willebrand disease (VWD) type 2A or acquired von Willebrand syndrome (aVWS) as a consequence of implantation of left ventricular assist devices (LVAD) are both characterized by a loss of von Willebrand factor (VWF) function. Loss of VWF function is however more severe in VWD type 2A than in LVAD patients.To compare VWF function in patients with VWD type 2A and LVAD-induced aVWS to highlight the differences in VWF activity and...
