Abstract
Quantitative assessment of left ventricular ejection fraction is an essenti al component of cardiac evaluation. We performed real-time 3-dimensional ec hocardiography In 56 consecutive patients who underwent multigated radionuc lide angiography. Thirteen patients were excluded for the following reasons : 5 for large size of left ventricle required for image acquisition, 5 for suboptimal image quality in realtime 3-dimensional echocardiography, and 3 for atrial fibrillation. Finally, we compared left ventricular ejection fra ction assessed by real-time 3-dimensional echocardiography and conventional 2-dimensional echocardiography with that obtained by multigated radionucli de angiography in 43 patients. Left ventricular ejection fraction was deter mined by real-time 3-dimensional echocardiography with the use of parallel plane-disks and sector plane-disks summation methods. A good correlation wa s obtained between both real-time 3-dimensional echocardiography methods an d multigated radionuclide angiography (r = 0.87 and 0.90, standard error of estimate = 3.7% and 4.2%), whereas the relation between the 2-dimensional echocardiography method and radionuclide angiography demonstrated a signifi cant departure from the line of identity (P <.001). In addition, interobser ver variability was significantly lower (P <.05) for the real-time 3-dimens ional echocardiography methods than that by the 2-dimensional echocardiogra phy method. Real-time 3-dimensional echocardiography may be used for quanti fication of left ventricular function as an alternative to conventional met hods in patients with adequate image quality.
