Prevention of Hemorrhage After Implantation of Mechanical Circulatory Support (PHAM)

July 9, 2019 updated by: University Hospital, Lille
Main objective of the study is to demonstrate that a prophylactic treatment with VWF factor concentrate after implantation of continuous-flow left ventricular assist device (CF-LVAD) reduces the frequency of clinically significant bleeding within 3 months after implantation in comparison to the usual care. Adult patients with functional defects of VWF measured after implantation of continuous LVAD are randomly assigned to prophylactic treatment.

Intervention / Treatment

Detailed Description

This time point was chosen because the bleeding events are maximal within the first 3 months after implantation.

  • Adult patients > 18 years who need a CF-LVAD due to advanced heart failure.
  • Functional To determine the potential indication of Wilfactin® in the field of CF-LVAD and avoid widespread use and to establish evidence-based recommendation To improve the knowledge of the role of VWF concentrate in bleeding and angiogenesis after CF-LVAD implantation and to provide some results about mechanism involved angiogenesis or hemostasis.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of patients with clinically significant bleeding within 3 months after implantation
Time Frame: 3 months
