Item 8.01. Other Events.

On December 6, 2010, World Heart Corporation announced that an investigator-initiated study that includes patients who had received the Levacor ventricular assist device (VAD) was the subject of a presentation in the Emerging New Technologies Section at the Fifth European Mechanical Circulatory Support Summit. Preliminary clinical data suggests that the Levacor VAD does not cause acquired von Willebrand Factor (vWF) deficiency, a condition that is linked to serious bleeding disorders and that has been associated with the use of current VADs.
