CTICasesSpontaneous Displacement of Cardiac Vein Lead
Imaging findings
Serial chest radiographs demonstrate spontaneous displacement and migration of the coronary sinus/cardiac vein lead of a cardiac resynchronization therapy defibrillator (CRT-D) device. The patient has a coexisting left ventricular assist device (LVAD).
Key takeaways
Coronary sinus lead migration or displacement can occur spontaneously without a history of trauma or surgery. Recognizing this on radiographs is important as it can lead to loss of ventricular resynchronization and pacing failure.
