It was reported that this lead exhibited loss of capture at pre-discharge check one day post implant.X-ray showed lead dislodged into main cs.Lead was then attempted in 3 different locations within left bundle branch (lbb) region but failed to advance very far in the septum.During third attempt, helix did not retract after over 60 turns, body turns and stylet jiggling.X-ray showed helix had uncoiled and appeared more like a hook.Lead was then removed with locking stylet with helix still extended with tissue.A new lead was successfully implanted.No adverse patient effects were reported.
