Leadless cardiac pacemakers: Paradigm shift in cardiac pacing

Since the first permanent endocardial pacemaker was implanted, there have been significant technological advancements in device programming, lead function, and battery longevity. However, the device design for the conventional transvenous pacemaker had essentially remained unchanged —a pulse generator connected to 1 or more transvenous leads. The complications associated with these devices were either related to subcutaneous pocket, including hematomas or skin erosions increasing the risk of infection, acute complications at the time of implant such as cardiac tamponade and p neumothorax, or late complications such as lead fracture, insulation failure, skin erosions, device externalization, infection, venous obstruction, and tricuspid regurgitation—all resulting in significant morbidity.
