title: Malfunction of an active fixation J-shaped screw-in atrial electrode lead: a case report.
abstract: 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.
