| Sensitivity (%) | Specificity (%) | Positive predictive value (%) | |
|---|---|---|---|
| Incomplete SAM rest | 70 | 64 | 54 |
| Aortoseptal angle ≤100° N=25 (16%) | 27 | 91 | 59 |
| Aortoseptal angle ≤100° and incomplete SAM rest N=8 (5%) | 12 | 99 | 88 |
| Aortoseptal angle ≤110° N=37 (23%) | 62 | 71 | 56 |
| Aortoseptal angle ≤110° and incomplete SAM rest N=19 (12%) | 23 | 95 | 74 |
