A, LVAD motor chamber showing clotted blood over the stator, the magnet, and cams, as well as over and under the retaining screw. The hardened blood clot effectively adheres the movable magnet and cams to the motor chamber housing and stator, thus impeding any rotation of the cams (0.5×). B, Back surface of the pusher plate showing clotted dry blood on the plate and ramps (0.5×).
