CTICasesPacemaker Lead Displacement by Jugular Catheter
Imaging findings
Serial chest radiographs demonstrate baseline placement of a pacemaker with the atrial electrode positioned normally. Following the removal of a right arm PICC line and subsequent insertion of a right jugular central venous catheter, the atrial electrode is noted to be displaced inferiorly into a position parallel with the ventricular electrode.
Key takeaways
Direct mechanical manipulation of central venous lines can inadvertently interact with and displace pre-existing cardiac hardware such as pacemaker or defibrillator leads. Radiologists should carefully evaluate lead positions on all post-procedural radiographs to identify lead dislodgement or displacement, which can lead to device malfunction or loss of capture.
