Repositioning and extraction of stylet-driven pacing leads with extendable helix used for left bundle branch area pacing

Conventional stylet-driven leads with extendable helix can be implanted successfully for left bundle branch area pacing (LBBAP) with a low acute complication rate. We report two cases in which lead repositioning after a first unsuccessful attempt to LBBAP was associated with fracture of the helix rotating mechanism and failure to fully extract the pacing lead.

Automated summary

For left bundle branch area pacing, conventional stylet-driven leads with extendable helix can be successfully implanted with low acute complication rate, but there is a risk of helix fracture and failure to fully extract the pacing lead during lead repositioning.
