| Cases/total (n) | ARO-cutoff (cm2) | ROC-area (95% CI) | Sensitivity/specificity (%) | |
| MRI-AR ⩾III | 26/45 | 0.28 | 0.99 (0.99 to 1.0) | 96/95 |
| CATH-AR ⩾III | 21/32 | 0.28 | 0.95 (0.85 to 1.0) | 90/91 |
| MRI-AR IV | 13/45 | 0.48 | 0.97 (0.90 to 1.0) | 83/97 |
MRI-AR and CATH-AR denote severity of aortic regurgitation by MRI and catheterisation, respectively. ARO-Cutoff, optimal cutoff for anatomic regurgitant orifice to detect the given MRI-AR and CATH-AR; ROC, receiver operator characteristic; CI, confidence interval.
