Key result
Direct visualization achieves successful retrieval of a chronically implanted leadless pacemaker in a reanimated swine.
Why the study?
Leadless pacemakers occasionally require retrieval due to complications such as elevated pacing thresholds, need for alternate therapy, pacemaker syndrome, or prosthetic valve endocarditis.
Case Report (n=1)
Demonstrates the feasibility of retrieving a chronically implanted leadless pacemaker using direct visualization in a swine model, providing educational images for clinicians and engineers.
Feasibility shown in swine model; hypothesis-generating for human retrieval and should not yet change practice.
Key Teaching Points•On occasion leadless pacemakers need to be retrieved despite outcomes showing reduced or minimal chronic complications. Complications might include elevated pacing thresholds, need for alternate therapy, pacemaker syndrome, or prosthetic valve endocarditis.•This case report shows the successful retrieval of a chronically implanted leadless pacemaker in a reanimated swine using direct visualization.•Images presented in this case report have notable educational value for clinicians and design engineers. •On occasion leadless pacemakers need to be retrieved despite outcomes showing reduced or minimal chronic complications.
