Three dimensional echocardiography (3D) is being applied in assessment of left ventricular (LV) volumes however, in vivo comparisons between two different 3D methods, K3 and TomTec, and validation by biplane cineventriculography (cine) have not been performed. Sixteen patients (mean age, 56±10 yrs) had cine and within 24 hours transthoracic 3D by K3 and TomTec. Comparisons of end diastolic (EDV) and end systolic (ESV) LV volumes are shown. (Figure Prersented) There were no significant differences in assessment of LV ejection fraction between cine and 3D however, correlations for comparisons were low due to a narrow range of measurements. LV volumes obtained by two different 3D methods correlated well and measurements by each 3D technique correlated highly with biplane cineventriculography.
