Key result
Sliding-contact technique yields 100% complication-free LBBAP success with continuous beat-to-beat monitoring.
Why the study?
Left bundle branch pacing with lumenless leads usually requires disconnecting pacing cables during rotation, which creates an electrical blind spot during septal advancement.
Does the sliding-contact technique enable continuous real-time electrical monitoring and safe procedural success during left bundle branch area pacing with a lumenless lead?
Observational (n=42)
Does the sliding-contact technique enable continuous real-time electrical monitoring and safe procedural success during left bundle branch area pacing with a lumenless lead?
A simple, zero-cost modification to a standard alligator pacing clip allows continuous real-time electrical monitoring during lumenless lead rotation for left bundle branch area pacing without specialized equipment.
May facilitate continuous LBBAP monitoring without added cost; hypothesis-generating and requires prospective validation before adoption.
Left bundle branch pacing with lumenless leads usually requires disconnecting pacing cables during rotation, creating an electrical blind spot during septal advancement. We describe the "sliding-contact" technique, a zero-cost modification enabling continuous real-time monitoring. Retracting the rubber shroud of a standard sterile alligator pacing clip reduces jaw tension, allowing unrestricted lead pin rotation while preserving electrical continuity. In 42 consecutive cases, LBBAP was successfully performed without complications. Beat-to-beat feedback on QRS morphology, impedance, and injury current was maintained throughout rotation, improving procedural precision and safety without specialized equipment.

Leonardo Marinaccio (2026) conducted an observational in Patients undergoing left bundle branch area pacing (LBBAP) (n=42). Sliding-contact technique (retracting the rubber shroud of a standard sterile alligator pacing clip during LBBAP with a lumenless lead) was evaluated on Procedural success and complication-free LBBAP with continuous real-time monitoring. The sliding-contact technique enabled successful left bundle branch area pacing without complications and with continuous beat-to-beat monitoring in all 42 consecutive cases (100%).
