Lead Advancement Using Only a Stylet-Driven Lead and Stylet Without a Delivery Catheter: Aiming for Left Bundle Branch Area Pacing Without a Guiding Catheter

By modifying the stylet-shaping curve and technique, lead advancement into the myocardium was feasible without using a delivery catheter. Although this study did not meet the strict criteria for LBBAP, our findings suggest that catheter-free LBBAP may be achievable with refined stylet shaping and standardized techniques.
