Nonuniform expansion and frame deformation of TAVR prostheses are associated with the development of hypoattenuating leaflet thickening (HALT), highlighting the importance of prosthesis design and deployment techniques.
Abstract
Nonuniform expansion of TAVR prostheses resulting in frame deformation, asymmetric leaflet, and smaller neosinus volume is related to occurrence of HALT in patients who undergo TAVR. These data may have implications for both prosthesis valve design and deployment techniques to improve clinical outcomes for these patients.
