Objective:The purpose of this study was to assess the left ventricle (LV) volumes and function acquired by real-time(RT) three-dimensional echocardiography (3D) in adult patients whose LV ejection fraction (LVEF) more than 45%, compared with magnetic resonance imaging (MRI) data. Methods:Unselected patients (n=37; 22 men; age, 57.78±17.23 years) with various cardiovascular disease were evaluated on the same day by MRI and RT3D. RT3D was performed with a Philips iE-33 echocardiographic system and LV volumes and function analyses with the assistance of TomTec software. The results for LV volumes and function obtained by manual tracing were compared with Signa 1.5-T MRI data.Results:The average MRI EDV was 110.48±33.50ml (60-208.76ml),ESV was 45.80±17.84 ml(19-102.4ml),EF was 59.13±7.24% (45.40-71.10%). The average RT3D EDV was 100.64±34.48ml (42.8- 211.9ml),ESV was 44.08 ±17.62ml (14.30 - 94.54ml),EF was 56.70±7.02% (35.1-73.4%). Compared with MRI values, EDV was underestimated by 3D (P＜0.01,r=0.842,y=0.867x+4.88,SEE=18.86 ml), with a mean difference of (-9.84±38.26) ml; ESV was also underestimated by 3D (P＞0.05,r=0.846,y=0.835x+5.82,SEE=9.53 ml) with a mean difference of( -1.71±19.68)ml. Ejection fraction by MRI was larger than that by 3D (P＜0.05,r=0.616,y=0.597x+21.38,SEE=5.61%), with a mean difference of (-2.42±12.5) %. There was good inter-and intra-observer correlation between RT-3D by two sonographers for volumes and ejection fraction.Conclutsions:The assessment of LV volume and ejection fraction from RT-3D data is feasible in patients . The volume and ejection fraction can be determined with high accuracy and low interobserver variability in patients with adequate echocardiographic image quality.
