TABLE 5.
Myocardial cut-off sign compared to sac morphology performance for left ventricular pseudoaneurysm. Head-to-head comparison of sensitivities and specificities involving the myocardial cut-off subjective assessment and objective measurements compared to ratios involving the sex width or depth compared to the neck width.
| Sensitivity | Specificity | |
|---|---|---|
| Subjective myocardial cut-off Reader 1 | 94% | 94% |
| Subjective myocardial cut-off Reader 2 | 100% | 78% |
| Objective: Measurement at 1 cm (bilateral measurements) | 91% | 97% |
| Objective: Measurement at 2 cm (bilateral measurements) | 100% | 51% |
| Sac width to neck width ratio >1.1:1 | 100% | 80% |
| Sac depth to neck width ratio > 1:1 | 80% | 80% |
