Limitations
The small number of LBBAP patients is a limitation of this single-center
study and our results need to be confirmed in larger studies. Both
implanters (JDP and FVH) have experience with both HBP and LBBAP.
Therefore, our results might not apply to implanters with less
experience in these new techniques. Follow-up in this study was limited
and longer follow-up in a larger population is needed to assess
long-term pacing characteristics. As no lead revision occurred within
our population, safety and feasibility of extraction procedures with
different types of pacing leads implanted at the left side of the septum
remains to be determined.
