CTICasesTAVI Leaflet Thrombus
Imaging findings
Post-TAVI study (2 months post-implantation) demonstrates thickened bioprosthetic valve leaflets with restricted mobility, particularly at the base, consistent with thrombus formation. All leaflets appear affected. Gated CT provides better visualization than echocardiography.
Key takeaways
Valve leaflet thrombi post-TAVI are more common than previously thought, even in the short term (2 months post-implantation), and can be seen on gated CT. The incidence may be associated with undersized valves. Treatment strategies for TAVI leaflet thrombus are still evolving.
