Comparison of actual and virtual volumes based on CMR calculations
| EF (%) | EDV (41–81 mL/m2) | ESV (12–21 mL/m2) | SV (26–56 mL/m2) | |
|---|---|---|---|---|
| Actual volume | 24 | 161 | 122 | 39 |
| Virtual volume | 45 | 98 | 54 | 44 |
Normal reference ranges given in brackets.
Virtual volumes were calculated using a predicted resection margin to assess whether cardiac function would improve post aneurysectomy. Volumes were calculated proportional to an estimated BSA of 1.8 m2.
BSA, body surface area; EDV, end-diastolic volume; EF, ejection fraction; ESV, end-systolic volume; SV, stroke volume.
