Abstract Background Clinical treatment strategies are often based on measurement of left ventricular ejection fraction (LVEF). There is limited evidence about variations in LVEF when measured by different imaging modalities. Purpose To investigate the intermodality variability of LVEF measured by two-dimensional echocardiography (2DE), three-dimensional echocardiography (3DE), cardiac magnetic resonance (CMR), and single photon emission computed tomography (SPECT) in patients with chronic coronary artery disease (CAD). Methods Patients from a multicenter study (DOPPLER-CIP – Determining optimal noninvasive parameters for the prediction of left ventricular remodeling in chronic ischemic patients) with chronic CAD were included. LVEF was measured by CMR and at least one additional modality. In each modality, LVEF was measured by a core laboratory independently of the other modalities. Measurements of LVEF by CMR were compared to 2DE, 3DE and SPECT using correlation and Bland-Altman plots. Results A total of 343 patients were included. Mean age was 63.9±8.3 years and 253 (74%) were males. Mean LVEF by CMR was 61.8±11.6%. Correlations between CMR LVEF and other modalities were moderate for 2DE and 3DE, and good for SPECT (Figure A-C). CMR had significantly greater correlation to SPECT, compared to 2DE and 3DE. Bland-Altman plots indicated relatively wide limits of agreement between all modalities, ranging from 31% to 42% (Figure, D-F). Mean absolute difference of LVEF between CMR and other modalities were 8.5% for 2DE, 9.0% for 3DE, and 8.3% for SPECT. The percentage of measurements that fell within a range of 5% difference compared to CMR LVEF was 41% for 2DE, 34% for 3DE and 37% for SPECT (all p>0.05). Conclusions In a multicenter study with chronic CAD patients, LVEF assessed by CMR had better correlation to SPECT, compared to 2DE and 3DE. However, there was considerable variability among all three modalities that were compared to CMR. Awareness of these variations are important in clinical management.

Objectives: Left ventricular ejection fraction can be measured by a variety of invasive and non-invasive cardiac techniques. This study assesses the relation of three diagnostic modalities to each other in the measurement of left ventricular ejection fraction: invasive contrast left ventriculography, two-dimensional echocardiography, and quantitative gated single-photon emission computed tomography. Methods: Retrospective chart review was conducted on 58 patients hospitalized with chest pain, who underwent left ventricular ejection fraction evaluation using each of the aforementioned modalities within a 3-month period not interrupted by myocardial infarction or revascularization. Results: The mean left ventricular ejection fraction values were as follows: invasive contrast left ventriculography (0.44±0.15), two-dimensional echocardiography (0.46±0.13), and gated single-photon emission computed tomography (0.37±0.10). Correlations coefficients and associated p values were as follows: invasive contrast left ventriculography versus two-dimensional echocardiography (r=0.69, p<0.001), invasive contrast left ventriculography versus gated single-photon emission computed tomography (r=0.80, p<0.0001), and gated single-photon emission computed tomography versus two-dimensional echocardiography (r=0.69, p<0.001). Conclusion: Our results indicate that strong positive correlations exist among the three techniques studied.
