Key result
Radiation therapy was successfully completed with an estimated cumulative dose of 101 cGy to the leadless pacemaker, with no pacemaker dysfunction observed at 6 weeks follow-up.
Why the study?
Radiation therapy can have adverse effects on cardiac pacemaker performance, presenting distinct considerations for leadless pacemakers implanted directly in the right ventricle.

Highlights the need for specific management strategies for patients with leadless pacemakers undergoing radiation therapy.
Wang et al. (2021) conducted a case report in Left breast cancer with a cardiac pacemaker (n=1). Leadless pacemaker (Micra AV) implantation prior to radiation therapy was evaluated on Pacemaker dysfunction and cumulative radiation dose. Radiation therapy was successfully completed with an estimated cumulative dose of 101 cGy to the leadless pacemaker, with no pacemaker dysfunction observed at 6 weeks follow-up.
