Imaging findings
Radiographic images of a pacemaker lead show an abnormal appearance in the right ventricular lead. There are clear disruptions and areas where the conducting electrodes are externalized, protruding from the insulation. This pattern is distinctly abnormal.
Key takeaways
Externalization of conducting electrodes, where the conductor coils protrude through the insulation, is a well-described complication specifically associated with the Riata pacemaker lead. This issue led to a recall of these leads and highlights the importance of careful scrutiny of pacemaker leads on imaging.
