Conduction System Pacing Using Stylet-Driven Leads. What Is the Difference?

His bundle and left bundle branch pacing are regarded as physiological options for permanent ventricular pacing because they use the fast-conducting specialized tissue for depolarization. The development, more than a decade ago, of a dedicated delivery kit using a lumenless lead, revolutionized the procedures and dramatically increased the success rate. After these consistent results, the industry is focusing now on releasing more tools for conduction system pacing.

We present two cases of conduction system pacing using a new delivery system based on stylet-driven leads and share our first impressions on the advantages and disadvantages compared to the lumenless technique.
