CTICasesFractured Coronary Vein Lead (CRTD Device)

Imaging findings
Initial chest radiograph showed appropriately positioned CRTD leads in the right atrial appendage, right ventricle, and a coronary vein. A follow-up radiograph a couple of months later showed a new fracture of the coronary vein lead. The heart also appeared slightly larger, and the azygos vein/SVC potentially more distended.
Key takeaways
This case demonstrates a relatively unusual and spontaneous fracture of a coronary vein lead of a CRTD device, occurring not long after implantation. Such fractures lead to device malfunction and require intervention. Careful review of lead integrity on follow-up imaging is important for device surveillance.
