|Imaging Modality and Sizing Criteria||Valve Size Chosen|
|23 mm||26 mm||29 mm|
|MDCT using adjusted criteria||13||23||5|
In the top row, valve sizes were chosen according to TEE measurements and the following guidelines for implantation: 23-mm valve for annulus ≥18.0 to ≤21.0 mm; 26-mm valve for >21.0 to ≤25.0 mm; and 29-mm valve for >25.0 to ≤28.0 mm. In the middle row, valve sizes were chosen from the MDCT area-derived diameter according to the same cutoff guidelines for implantation. In the bottom row, valve sizes were chosen from the MDCT area-derived diameter but adjusted by 1.5 mm to account for the mean difference in this measurement from TEE, hence: 23-mm valve for annulus ≥19.5 to ≤22.5 mm; 26-mm valve for >22.5 to ≤26.5 mm; and 29-mm valve for >26.5 to ≤29.5 mm.
