3.6 LBBAP success rate and associated complications
In the included studies, the highest success rate was 100%, the lowest
success rate was 66.7%, and the average success rate was 92%.
It should be noted in particular that the study conducted by author Chen
Lu was a discussion of the success rate, safety and efficacy of LBBAP
surgery.Their retrospective case study was divided into two distinct
phases, namely, the learning phase and the proficient surgery phase,and
there was a significant difference in the success rates of the two
phases, which were 55.6% and 88.9, respectively, with a mean success
rate of 66.7%.
In terms of surgery-related complications, one patient in Xiaofei Li’s
study developed a ventricular septal perforation shortly after surgery
and successfully repaired it; In
Pugazhendhi Vijayaraman’s study, three patients presented with acute
lead dislodgments within 24 hours after surgery, and these three
patients subsequently underwent surgery and were successfully repaired.
In the third patient, another ventricular septal perforation occurred
during the re-repair procedure, and the electrode was re-fixed slightly
below the previous fixation point. One patient developed a pericardial
effusion as a result of uninterrupted oral anticoagulation, which
disappeared after puncture
drainage;
In Yuqiu Li’s study, one patient who was receiving dual antiplatelet
therapy developed a pockethematoma;
In Jingfeng Wang’s study, one
patient suffered an intraoperative septal lead perforation and three
patients developed mild pocket hematoma within one month of surgery, and
all hematoma was relieved by reinforced elastic bandage compression. Two
patients experienced lead dislodgement. One was noted 2 months
post-implant, who received LBBAP again; while another occurred 4 months
post-implant with the lead relocated to RVS.
