Novel approach to left bundle branch area pacing lead implantation using a 3-dimensional stylet
Authors' conclusion
LBBAP lead implantation with the use of a manually shaped stiff 3D stylet is feasible and results in comparable outcomes to those achieved with leads implanted by dedicated preshaped delivery catheters.
