Real-time three-dimensional echocardiographic left ventricular systolic assessment: Side-by-side comparison with 64-slice multi-detector cardiac computed tomography

Abstract

Aims: To investigate by real-time 3D echocardiography (RT3DE) and cardiac computed tomography (CCT) the analysis of left ventricle ejection fraction (LVEF) and volumes. Methods and Results: A total of 67 patients (37 males, 55 ± 11 years) were studied prospectively by RT3DE and by 64-slice CCT. RT3DE data: LVEF ranged from 30 to 78.6 (63.1 ± 7.33); left ventricular end-diastolic volume (LVEDV) from 44.1 to 210 (104.9 ± 29.7) mL; left ventricular end-systolic volume (LVESV) from 11.4 to 149 (38.9 ± 19.3) mL. CCT data: LVEF ranged from 28 to 86 (66 ± 8.4); LVEDV from 51 to 212 (110.3 ± 31.2) mL; LVESV from 7 to 152 (38.2 ± 19.2) mL. Correlations relative to RT3DE and CCT were: LVEF (r: 0.79, P < 0.0001); LVEDV (r: 0.82, P < 0.0001); and LVESV (r: 0.91, P < 0.0001). Conclusion :It was observed adequate correlation between RT3DE and CCT ventricular systolic function and geometry assessment. © The Author 2009.
