CTICasesPacemaker Lead Discontinuity
Imaging findings
A subtle discontinuity in an atrial pacemaker lead, visible upon close inspection of the costoclavicular space.
Key takeaways
The costoclavicular space is a high-stress area for pacemaker wires. When evaluating for suspected lead fracture, zooming in on radiographs of this region is essential. Discontinuity may be subtle even when there is clinical evidence of abnormal impedance.
