Coagulation and complications of left ventricular assist device therapy: a primer for emergency nurses.

Implantation of left ventricular assist devices (LVADs) is becoming more common with the advancement of mechanical circulatory support technology and the continued insufficient number of organ donors available for heart transplantation. Modern LVADs provide a mechanically induced, nonpulsatile, continuous blood flow that drastically alters the hemodynamic and coagulation profile of patients using these devices. In addition to the risk of bleeding and thrombotic events, LVAD support can also lead to arrhythmias and infection.
