Three Easy Steps to Avoid Prosthesis–Patient Mismatch
| Step I: Calculate the patient’s body surface (BSA) area using the formula: |
| BSA = ([Weightkg]0.425 × [heightcm]0.725) × 0.007184 |
| Step II: Determine the minimal requirement for prosthetic valve effective orifice area (EOA) to avoid prosthesis–patient mismatch. |
| Patient BSA (m2) | Minimal Valve EOA (cm2) for Indexed EOA >0.85 cm2/m2 (Ideal) | Minimal Valve EOA (cm2) for Indexed EOA >0.80 cm2/m2 | Minimal Valve EOA (cm2) for Indexed EOA >0.75 cm2/m2 |

| Step III: Choose a prosthesis using reference values for EOA of different types and sizes of prostheses (see Table 2). | |||
