CTICasesPacemaker Lead Dislodgement
Imaging findings
Chest radiograph and CT show a cardiac pacemaker lead, intended for the coronary sinus/cardiac resynchronization therapy, dislodged and migrated into the left ventricle (going through the coronary sinus into the inferior interventricular vein).
Key takeaways
Dislodgement or migration of cardiac pacemaker leads into the left ventricle can occur following central venous access or right heart catheterization, likely due to inadvertent wire snagging or spontaneous displacement.
