Valve sizing in BAV and TAV.
| Parameter | BAV | TAV | p-value |
|---|---|---|---|
| Mean ± SD or n/N (%)(n = 223) | Mean ± SD or n/N (%)(n = 215) | ||
| Annulus size (mm2) | 492.5 ± 105.0 | 456.9 ± 85.8 | <0.001 |
| Valve sizinga | <0.001 | ||
| Oversized | 5/223 (2.2) | 8/215 (3.7) | |
| Within size | 138/223 (61.9) | 186/215 (86.5) | |
| Undersized | 80/223 (35.9) | 21/215 (9.8) |
Oversizing was defined as: measured annulus size < min. area declared by valve size. Undersized was defined as: measured annulus size > maximal area declared by valve size.
