Cardiac conduction system pacing lead implantation: delivery tool is the clue to success

Abstract

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.
