A 70-year-old man with a bioprosthetic aortic valve undergoes 4D cardiac CT to evaluate suspected prosthetic valve thrombosis. Which finding is most suggestive of haemodynamically significant bioprosthetic valve thrombosis?

Correct answer: D — Hypoattenuated leaflet thickening (HALT) with reduced leaflet motion (RLM) involving more than one leaflet

Explanation lettering: D = shown as A · C = shown as B · B = shown as C · A = shown as D

Per the 2025 ESC/EACTS VHD Guidelines, 4D CT is recommended for evaluation of suspected bioprosthetic valve thrombosis. HALT with RLM involving more than one leaflet is associated with haemodynamic significance. Minimal thickening without restricted motion (A) may be subclinical. Paravalvular leak (C) suggests a different pathology. Pannus (D) is a chronic issue. Aortic root dilatation (E) is unrelated.
