Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Comparison of 2D mitral EPSS-based LVEF & 3D mitral EPSS-based LVEF with 2D LVEF measured from modified Simpson’s formula in patients with normal LV systolic function (LVEF more than 52% in men & 54% in women) & their correlation with LVEF obtained by 3DE volumetric assessment as a reference method. 2. Correlation of 3D mitral EPSS area with 2DE modified Simpson’s LVEF & 3DE LVEF in patients with good LV & deranged LV function. We also would try to derive a formula to calculate LVEF using 3D EPSS area. Timepoint: Pre CPB initiation | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Comparison of LVEF obtained by 2D & 3D mitral EPSS, modified Simpson’s formula and their correlation with LVEF obtained by 3DE volumetric assessment as a reference method. i.) in patients with deranged LV systolic function ii.) in patients without dilated LV iii.) formula in patients with dilated LV 2. Correlation of 3D mitral EPSS area with measured LVEF in patients with dilated LV and non-dilated LV. We also would try to derive a formula to calculate LVEF using 3D EPSS area. 3. To assess the correlation between 3D EPSS on postoperative outcome parameters 4. To ascertain the intraobserver variability and interobserver variability.Timepoint: Pre CPB initiation Post extubation Pre discharge from ICU | — |
