Echocardiographic Characteristics of the Matched Patients
| Characteristic | Aortic Valve Morphological Feature | OR (95% CI) | P Value | |
|---|---|---|---|---|
| BAV | TAV | |||
| (n=274) | (n=274) | |||
| AVA, cm2 | 0.80 (0.60–1.00) | 0.90 (0.70–1.10) | 2.80 (1.38–5.67) | 0.004 |
| Mean AV gradient, mm Hg | 45 (33–58) | 37 (27–49) | 0.97 (0.96–0.98) | <0.001 |
| Peak AV gradient, mm Hg | 73 (55.3–92.8) | 62 (47–78) | 0.98 (0.98–0.99) | <0.001 |
| Aortic regurgitation (scale, 0–4) | 0 (0–1) | 0 (0–1.5) | 1.00 (0.98–1.01) | 0.483 |
Data are presented as median (interquartile range). AV indicates aortic valve; AVA, AV area; BAV, bicuspid AV; OR, odds ratio; and TAV, tricuspid AV.
