Abstract
BACKGROUND:: METHODS:: RESULTS:: LV end-systolic and end-diastolic volumes were underestimated by 2D and 3D unenhanced echocardiography compared with cardiac magnetic resonance. Contrast enhancement resulted in similar significant increases in LV volumes on 2D and 3D echocardiography. The mean percentage of interreader variability for LV EF was reduced from 14.3% (95% confidence interval [CI], 11.7%–16.8%) for unenhanced 2D echocardiography and 14.3% (95% CI, 9.7%–18.9%) for unenhanced 3D echocardiography to 8.0% (95% CI, 6.3%–9.7%; P < .001) for contrast-enhanced 2D echocardiography and 7.4% (95% CI, 5.7%–9.1%; P < .01) for contrast-enhanced 3D echocardiography and thus to a similar level as for cardiac magnetic resonance (7.9%; 95% CI, 5.4%–10.5%). A similar effect was observed for interreader variability for LV volumes. CONCLUSIONS
