CTICasesCoreValve Dislodgement and Fixation with Palmaz Stent During TEVAR

Imaging findings
Intra-procedural angiography shows a Medtronic CoreValve device dislodged substantially down into the ventricle. Following snaring and repositioning, a Palmaz stent was deployed to overlap and fix the CoreValve device in the aortic position. A post-operative radiograph clearly shows both the CoreValve device and the additional Palmaz stent.
Key takeaways
Aortic valve prostheses can dislodge during TEVAR procedures. Interventional techniques can be employed to snare and reposition the device. In cases of recurrent dislodgement, an additional stent, such as a Palmaz stent, can be deployed to fix the CoreValve device in position.
