Key result
Modified C304 SelectSite tool linked to ~92% His bundle implantation success versus alternative techniques.
Why the study?
To analyze the success rate and other intraprocedural parameters of His bundle pacing lead implantation using different approaches.
Does a modified C304 SelectSite delivery tool improve the success rate of His bundle pacing lead implantation in patients requiring pacing?
Observational (n=32)
Does a modified C304 SelectSite delivery tool improve the success rate of His bundle pacing lead implantation in patients requiring pacing?
Using a modified C304 SelectSite delivery tool significantly improves the success rate of His bundle pacing lead implantation compared to standard techniques.
Modified C304 tool was associated with higher His bundle pacing success; hypothesis-generating and requires randomized confirmation before practice change.
Aim . To analyze the success rate and other intraprocedural parameters of implantation His bundle pacing lead using different approaches. Methods . Since 2018 to 2022 we have tried His bundle lead implantation in 32 pts. During implantation 4 different approaches were used: on-stylet in 6 pts (19%), on-stylet over the delivery tool in 9 pts (28%), over the C304 SelectSite (Medtronic, USA) delivery tool in 10 pts (31%), over the modified C304 SelectSite delivery tool in 12 pts (37%). Results . Four studied implantation approaches did not differ by means of procedure duration as well as lead parameters. The success rate of implantation using modified C304 SelectSite delivery tool was higher than using other 3 techniques (91,7% vs 44%, p-0,006).Conclusion. His bundle lead implantation success depends significantly on chosen implantation technique.

Gorev et al. (2023) conducted an observational in Patients requiring His bundle pacing lead implantation (n=32). Modified C304 SelectSite delivery tool vs. Other techniques (on-stylet, on-stylet over delivery tool, standard C304 SelectSite) was evaluated on Success rate of implantation (p=0.006). His bundle lead implantation using a modified C304 SelectSite delivery tool achieved a significantly higher success rate compared to three other techniques (91.7% vs 44%, p=0.006).
