To investigate the determinants of paravalvular leak (PVL) occurring after transcatheter aortic valve implantation (TAVI). ⋯ The procedure-related THV/annulus sizing ratio was an important determinant of the degree of PVL after TAVI, whereas the MDCT-derived anatomical measurements of the aortic root and AVC were not predictors of PVL.

To investigate whether clivus height (CH; the distance of the basion above Chamberlain's line) could be used to diagnose basilar invagination (BI) at computed tomography (CT). ⋯ Although not better than CL (the distance of the odontoid tip above Chamberlain's line), measurement of CH at CT is reproducible and can diagnose patients with BI.
