Conclusion
In our experience, LBBP using the EIS catheter, and the stylet driven IS-1 pacing lead is safe and feasible in routine clinical practice. The learning curve involved in adopting this delivery system is gentler, as it utilizes two existing platforms: namely the Agilis steerable introducer commonly used in electrophysiology studies, and stylet driven leads. The ability to shape, as well as to vary the deflection of the catheter would allow for better success rates at LBBP, especially in patients with challenging anatomies.
