Leadless pacemaker implantation quality: importance of the operator’s experience
Key result
Higher operator experience was associated with better leadless pacemaker implantation quality (OR 1.09; 95% CI 1.00-1.19; P=0.05) and increased procedural efficiency.
Why the study?
Recent real-world data raised concerns regarding the learning curve of new operators and implantation quality during leadless pacemaker implantation.
Does operator experience improve implantation quality and procedural efficiency in patients undergoing leadless pacemaker implantation?
Population
111 Micra TPS implantation cases across two large tertiary referral hospitals
Comparison
Implantation quality and procedural efficiency across different levels of operator experience
Design

Cite This Study
Haeberlin et al. (2020) conducted an observational in Leadless cardiac pacemaker implantation (n=111). Operator experience vs. Less operator experience was evaluated on Implantation quality (absence of complications, good electrical performance, acceptable fluoroscopy duration) (OR 1.09, 95% CI 1.00-1.19, p=0.05). Higher operator experience was associated with better leadless pacemaker implantation quality (OR 1.09; 95% CI 1.00-1.19; P=0.05) and increased procedural efficiency.
