Valve size assessment by comparing angiogram balloon sizing and multislice computed tomography measurements
| Patient number | Angiogram balloon sizing (narrowest diameter) (mm) | MSCT narrowest diameter (mm) | Native valve area by MSCT (mm2) | Native valve area by angiogram balloon sizing (mm2) | Valve size used (mm) | Valve area of Myval® used (internal diameter) (mm2) | Percentage increase to valve area (angiogram balloon sizing) | Percentage increase to valve area (MSCT scan) |
|---|---|---|---|---|---|---|---|---|
| #1 | 24 | 21 | 346 | 452 | 27.5 | 589 | 23 | 41 |
