The reported event of left ventricle-setscrew stuck to the wrench was confirmed.Analysis of the device revealed that the user of the torque wrench did not align the wrench tip to go into the inset of the setscrew.The wrench was inserted with the corners of the wrench tip going into, being wedged and forced into the inset walls.This resulted in the wrench being stuck in the inset of the setscrew.The setscrew was then pulled out of the device through the septum attached to the wrench tip.This is related to the user's incorrect use of the wrench.A non-abbott torque wrench was also used which is not recommended.
