Echocardiographical risk factors for redo mitral valve (MV) surgery in the whole study cohort (Cox regression model). Parameters were collected prior to initial mitral valve repair.
| Multivariate Analysis | Entire Study Cohort (n = 215) | |||
|---|---|---|---|---|
| Variable | Redo Group | Control Group | HR | p-Value |
| Systolic PAP ≥ 50 mmHg | 16 (21%) | 13 (9%) | 2.3 | 0.02 |
| TR ≥ moderate | 13 (17%) | 14 (10%) | 1.04 | 0.87 |
| AML length (mm) | 30 ± 8 | 30 ± 7 | 0.5 | 0.29 |
| Pmean > 5 mmHg | 7 (9%) | 2 (1%) | 3.3 | 0.001 |
| LVEF ≤ 45% | 15 (19%) | 14 (10%) | 2.1 | 0.05 |
| LVEDD (mm) | 62 ± 11 | 61 ± 9 | 2.3 | 0.78 |
| MR at discharge ≥ moderate | 17 (22%) | 7 (5%) | 5.8 | 0.002 |
MV, mitral valve; PAP, pulmonary artery pressure; TR, tricuspid regurgitation; AML, anterior mitral leaflet; Pmean, mean pressure gradient; LVEF, left ventricular ejection fraction; LVEDD, left ventricular enddiastolic diameter; MR, mitral regurgitation; HR, hazard ratio.
