[Evaluation of left ventricular volume and ejection fraction using three-dimensional transesophageal echocardiography].
Left ventricular (LV) volume and ejection fraction (EF) derived from three-dimensional echocardiography using a multiplane transesophageal probe (3D-TEE) were compared with LV volume and EF obtained from left ventriculography (LVG) in 14 patients (mean age: 61 years). Left ventricular volumes were calculated using a summation of disks algorithm based on multiple reconstructed short-axis cross-sections from 3D data. Left ventricular volume (end-diastole and end-systole) and EF from 3D-TEE were compared with those from LVG using linear regression analysis. Three-dimensional TEE demonstrated excellent correlations with LVG for measuring LV volume (r = 0.97, SEE = 11 ml) and EF (r = 0.95, SEE-4%), respectively. Three-dimensional TEE is useful for the measurement of LV volume and EF in the clinical setting.
