4.1 Feasibility of LBBAP in HFmrEF
All studies included in this meta-analysis performed LBBAP using
lumenless pacing leads, with an average acute success rate of 91.3%. In
one case series wherein LBBAP was performed in patients with HFmrEF
using stylet driven leads, the success rate was 100%
(n=4)38 Although procedure-related complications of
septal perforation, pneumothorax, pocket infection, pocket hematoma, and
lead dislodgements occurred during the follow-up period, no major
implantation-related complications were observed.
