CTICasesInadvertent Right Ventricular Lead Loop of a CRT-D Device
Imaging findings
Chest radiographs of a patient with a cardiac resynchronization therapy defibrillator (CRT-D) device demonstrate an unusual, highly redundant loop of the right ventricular lead that appears to course into the right ventricular outflow tract, back through the tricuspid valve, and into the coronary sinus.
Key takeaways
Pacemaker or ICD lead redundancy and malposition can sometimes occur inadvertently during placement. Recognizing abnormal lead looping on chest radiographs is essential for identifying potential lead malfunction or mechanical complications.
