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.
