Permanent His bundle pacing using a Biotronik stylet-driven Lead: feasibility and early outcomes from a single centre.

Abstract

His bundle pacing (HBP) has been shown to be a good alternative to conventional cardiac resynchronisation therapy (CRT) and may theoretically provide an additional benefit where CRT has a response deficit of at least 30%. HBP requires mapping and identification of the His bundle, and to this purpose the lead delivery is challenging. This first-reported case series from Africa shares early experience with different pacing indications (complete heart block and pre-existing right ventricular pacing; heart failure with left bundle branch block) for using a standard 5.6F, Solia S 60, IS-1, ProMRI bipolar pacing lead and an 8.7F Selectra 3D introducer guide, 32-39-cm working length with 40/55/65-mm proximal radii (Biotronik). These cases highlighted the importance of appropriate programming when implanting HBP and of assessing the conduction system to predict patients who might benefit from HBP and additional left ventricular lead implant. The Biotronik Solia lead and delivery guide were found to be feasible and reliable in these cases. The Biotronik conduction system pacing tools were used with good acute outcomes in patients with different pacing indications.
