Hypoattenuated leaflet thickening (HALT), or subclinical leaflet thrombosis, is a focal area of hypoattenuating leaflet thickening seen in transcatheter aortic valve prostheses which begins at the leaflet insertion on the valve frame seen on CT.
HALT is a known complication of transcatheter aortic valve replacement (TAVR). There is concern that it may compromise valvular durability and increase the risk of thromboembolism, stroke, or transient ischemic attacks.
