Table 2.
Measures of mitral valve regurgitation and leaflet function before and after application of cerclage tension (n=10 except for velocity-encoded MRI, n=5).
| Baseline | Tension | p | |
|---|---|---|---|
| Mitral regurgitation | |||
| Regurgitant fraction by slice-tracking velocity-encoded MRI | 22.8 ± 12.7 | 7.2 ± 4.4 | 0.04 |
| Categorical mitral regurgitation total (Grade 1–4) | 1.7 ± 0.8 | 0.7 ± 0.5 | 0.01 |
| Mitral valve coaptation | |||
| Mitral valve tenting area (cm2) | 2.1 ± 0.5 | 1.5 ± 0.5 | 0.01 |
| Posterior displacement of line of coaptation (mm) | 25.7 ± 4.0 | 21.2 ± 4.8 | 0.01 |
| Leaflet coaptation length (mm) | 3.0 ± 2.4 | 4.8 ± 1.6 | 0.12 |
