Table 4 Prediction model for mitral prosthesis size
From: Mitral prosthetic size predictor in minimally invasive mitral valve replacement
Calculated diameter | Whole population | Mechanical valve group | Tissue valve group |
|---|---|---|---|
Mean TTE diameter | 17.28 + 0.23 × d (R2 = 0.493) | 17.51 + 0.23 × d (R2 = 0.464) | 16.19 + 0.27 × d (R2 = 0.554) |
Mean diameter on CT lowest plane | 15.09 + 0.36 × d (R2 = 0.461) | 16.39 + 0.32 × d (R2 = 0.396) | 12.74 + 0.44 × d (R2 = 0.572) |
Area-derived diameter on CT highest plane | 14.88 + 0.33 × d (R2 = 0.442) | 16.10 + 0.29 × d (R2 = 0.386) | 12.79 + 0.38 × d (R2 = 0.533) |
