[Successful use of recombinant factor VIIa in the control of a massive bleeding in two patients with biventricular assist device (Thoratec)]. / Utilisation bénéfique de facteur VIIa recombinant chez deux patients porteurs d'une assistance biventriculaire (Thoratec).

Massive bleeding is a dreaded complication of biventricular mechanical assistance implantation. Its origin is multifactorial. Blood products transfusion associated with correction of coagulopathy are sometimes insufficient. We report two cases of massive bleeding after a Thoratec biventricular assistance implantation. After surgical haemostasis failure and despite the correction of coagulation disorders, a major bleeding persisted, so these patients received a single injection of 90 microg/kg of rFVIIa. This allowed in both cases a significant reduction of the bleeding and the restoration of normal haemodynamic conditions. This treatment was not complicated by any thrombotic accident.
