Table 4.
Mean mitral regurgitant volume (RV), regurgitant fraction (RF) and corrected RF, as derived from the four different methods
SC at AoV | SSC at AoV | SC at STJ | SC at AAo | p | |
---|---|---|---|---|---|
# Patients | 98 | 98 | 82 | 97 | |
Mitral RV [mean (SD)], ml | 10.8 (10.1) | 4.8 (8.4) | 16.1 (10.3) | 17.9 (11.6) | < 0.001 |
Mitral RF [mean (SD)], % | 8.9 (8.5) | 3.9 (7.6) | 13.5 (7.4) | 15.3 (9.7) | < 0.001 |
Corrected mitral RF [mean (SD)] | 10.8 (10.0) | 4.7 (8.7) | 15.9 (9.2) | 17.4 (11.0) | < 0.001 |
Mitral RV was calculated using the formula LV SV − aortic forward flow. Mitral RF was calculated using the formula . Corrected mitral RF was calculated using the formula . All follow up pairwise comparisons had adjusted p-values < 0.05, except corrected mitral RF derived from SC at STJ vs SC at AAo
