Multivariable analysis of predictors of time to DSS reoperation
| HR | 95% CI | p Value | |
|---|---|---|---|
| Age at DSS resection (↓1 year) | 1.24 | 1.08 to 1.43 | 0.003 |
| Preoperative gradient ≥60 mm Hg | 2.23 | 1.03 to 4.83 | 0.04 |
| Any peeling (AoV or MV) | 2.52 | 1.21 to 5.28 | 0.01 |
| DSS to AoV distance (systole) <7.0 mm | 4.03 | 1.18 to 13.8 | 0.03 |
| Aortic valve stenosis | 2.58 | 1.22 to 5.45 | 0.01 |
AoV, aortic valve; DSS, discrete subaortic stenosis; MV, mitral valve.
