Key result
Fixation stylet fracture occurred during helix extension and retraction maneuvers in two cases of active fixation leads, resulting in lead inoperability and abandonment.
Case Report (n=2)
Highlights a specific mechanical complication (fixation stylet fracture) associated with active fixation J-shaped atrial leads and describes a successful removal technique.
Raises caution for stylet fracture during active fixation lead maneuvers; leaves open incidence and design improvements.
Active fixation leads, using active grasping devices, ensure good postoperative lead fixation, long-term performance, and make possible later lead removal on demand. However, these delicate designs have not been without practical difficulties. We present two cases of fixation stylet fracture during helix extension and retraction maneuver respectively with resultant lead inoperability and abandonment. The fixed leads could be removed by torquing the entire lead counterclockwise.

Lee et al. (1997) conducted a case report in Fixation stylet fracture of active fixation leads (n=2). Active fixation J-shaped screw-in atrial electrode lead was evaluated on Fixation stylet fracture and lead inoperability. Fixation stylet fracture occurred during helix extension and retraction maneuvers in two cases of active fixation leads, resulting in lead inoperability and abandonment.
