Does automated measurement of LV volumes and LVEF using the Philips EPIQ system provide accurate and more efficient assessments compared to manual tracing in patients in sinus rhythm?
Automated echocardiographic measurement of LV volumes and ejection fraction using the Philips EPIQ system is significantly faster than and highly concordant with manual tracing.
Absolute Event Rate: 116% vs 217%
p-value: p=< .0001
PURPOSE: To assess the efficiency and reproducibility of automated measurements of left ventricular (LV) volumes and LV ejection fraction (LVEF) in comparison to manually traced biplane Simpson's method. METHOD: This is a single-center prospective study. Apical four- and two-chamber views were acquired in patients in sinus rhythm. Two operators independently measured LV volumes and LVEF using biplane Simpson's method. In addition, the image analysis software a2DQ on the Philips EPIQ system was applied to automatically assess the LV volumes and LVEF. Time spent on each analysis, using both methods, was documented. Concordance of echocardiographic measures was evaluated using intraclass correlation (ICC) and Bland-Altman analysis. RESULTS: . ICC and Bland-Altman analysis showed good agreements between manual and automated methods measuring LVEF, end-systolic, and end-diastolic volumes. The average analysis time was significantly less using the automated method than manual tracing (116 vs 217 seconds/patient, P < .0001). CONCLUSION: Automated measurement using the novel image analysis software a2DQ on the Philips EPIQ system produced accurate, efficient, and reproducible assessment of LV volumes and LVEF compared with manual measurement.
Hovnanians et al. (Tue,) conducted a observational in Patients in sinus rhythm. Automated measurement using image analysis software a2DQ on the Philips EPIQ system vs. Manually traced biplane Simpson's method was evaluated on Average analysis time per patient (p=< .0001). Automated measurement of LV volumes and LVEF using the Philips EPIQ system significantly reduced average analysis time compared to manual tracing (116 vs 217 seconds/patient, P < .0001).
