CTICasesEmbolized/Dislodged Transcatheter Tricuspid Valve Prosthesis in the Coronary Sinus
Imaging findings
Follow-up chest radiographs and CT planning scans show a transcatheter tricuspid valve prosthesis that has dislodged from its original tricuspid position and become lodged within the ostium of the coronary sinus. Retrospective review of multiple prior chest radiographs demonstrates that this migration occurred years prior and remained in a stable, unrecognized position. Gated cardiac CT shows the valve in the coronary sinus, with a transient appearance of laminar thrombus or contrast pooling that cleared on subsequent imaging.
Key takeaways
Transcatheter valve prostheses can dislodge and embolize to atypical locations, such as the coronary sinus, and may remain hemodynamically stable or clinically unrecognized for several years. This case underscores the crucial clinical practice of comparing current radiographs with the earliest baseline post-procedural films rather than only the immediate prior study, which would have erroneously documented a stable and unchanged position.
