The danger of using a sledgehammer to crack a nut: ROTEM-Guided administration of recombinant activated Factor VII in a patient with refractory bleeding post-ventricular assist device implantation

Abstract

Recombinant activated factor VII (rFVIIa) is currently approved for treating or preventing hemorrhage in patients with hemophilia, Glanzmann's thrombasthenia, or congenital FVII deficiency. Its "off-label" use for massive bleeding in the setting of trauma or surgery has been increasing because of demonstrated efficacy. However, the use of rFVIIa also carries a high thrombo-embolic risk. This is particularly true in cardiac surgery patients, especially those treated with mechanical circulatory support. We describe the case of a patient treated with a biventricular assist device in our center, in whom severe bleeding was treated in a targeted manner, using rotational thromboelastometry to guid..
