CT-Angiography–Based Evaluation of the Aortic Annulus for Prosthesis Sizing in Transcatheter Aortic Valve Implantation (TAVI)–Predictive Value and Optimal Thresholds for Major Anatomic Parameters
Table 3
Primary anatomic parameters of the aortic annulus, N(%), mean ± SD or median [interquartile range] as well as “virtual diameters” derived from the mean of long axis and short axis, from annulus circumference and annulus area.
