Abstract Objective: To evaluate left ventricular(LV) volume and LV systolic function with real-time three-dimensional echocardiography(RT-3DE) in normal newborns. Methods: A retrospective review of 93 normal newborns with RT-3DE were performed, the LV end diastolic volume(LVEDV), LV end systolic volume(LVESV), stroke volume(SV) and LVEF were measured by 3DQ Advance analysis． At the same time, the LVEDV, LVESV, SV and LVEF from biplane Simpson’s method were measured as well. To evaluate whether they were affected by gender, gestational age, birth weight and heart rate. Results: There were significant differences between RT-3DE and biplane Simpson’s method for LVEDV, SV and LVEF(P<0.01). There was excellent correlation between RT-3DE and biplane Simpson’s method for LVEDV, LVESV, SV and LVEF(r=0.94, 0.87, 0.94, 0.75, P<0.001). Gender, gestational age and heart rate did not affect any of these parameters, while birth weight correlated positively with LVEDV, LVESV, SV. Conclusion: As a non-invasive 3D imaging technology, the RT-3DE can quantify LV volume and systolic function rapidly and accurately with clinical significance.
