Key result
Post-TAVI CT frequently detects HALT in balloon-expandable valves, though key predictors remain incompletely defined.
Why the study?
What are the incidence and predictors of hypo-attenuated leaflet thickening (HALT) in patients receiving intra-annular balloon-expandable transcatheter heart valves?

This study aims to define the incidence and predictors of hypo-attenuated leaflet thickening (HALT) in patients receiving intra-annular balloon-expandable valves.
Hypo-attenuated leaflet thickening (HALT) is frequently detected on post–transcatheter aortic valve implantation (TAVI) computed tomography (CT). Determinants of HALT in intra-annular balloon-expandable valves (BEVs) remain incompletely defined.

Liccardo et al. (2026) studied this question. Hypo-attenuated leaflet thickening is frequently detected on post-TAVI computed tomography, but its determinants in balloon-expandable valves remain incompletely defined.
