CTICasesPacemaker Lead Indentation
Imaging findings
A zoomed-in view of a post-operative chest radiograph shows a focal, sharp indentation or crimp in a pacemaker lead just distal to the generator header. The lead remains functional, and the appearance is stable.
Key takeaways
A focal indentation or crimp in a pacemaker lead near the generator is often caused by an excessively tight suture placed around the protective plastic suture sleeve used to anchor the lead in the prepectoral pocket. This finding should not be mistaken for a lead fracture if the device is functioning normally.
