Comparison of left ventricular ejection fraction values obtained using invasive contrast left ventriculography, two-dimensional echocardiography, and gated single-photon emission computed tomography

Abstract: 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 v… Show more

“…Multiple trials have compared ECHO and SPECT to each other (Table 3) [10][11][12][13][14][15] and, at the same time, ECHO with CMR 5,17 and SPECT with CMR. 5,18 In three studies, patients underwent all imaging techniques, including SPECT, ECHO without contrast, and CMR.…”

“…This study informs the practitioner of the possible discrepancies between LVEF measured by ECHO and SPECT, especially when the discrepancy of LVEF by the two techniques may be as much as 10%. [10][11][12][13][14][15] Rijnierse et al 23 reported that 29 of 149 (19%) patients had an LVEF by CMR of <35% but an LVEF by ECHO of >35%, and thus these 29 patients would not have been eligible for ICD therapy by ECHO criteria. However, appropriate device therapy discharges occurred at a rate of 2.1% per year in this group who would not have received an ICD had only the ECHO criteria been used.…”

“…LV function will be measured with echocardiography at baseline (visit 1) as well as 6 (visit 5), 12 (visit 6), 18 (visit 7) and 24 (visit 8) months after infusion, using standardized imaging protocols to calculate ejection fraction using the Simpson’s rule. Although a discrete positive correlation has been described among LV angiography and echocardiography estimates [39], LVEF measurements by various techniques are generally not interchangeable [40]. However, LVEF changes trends measured with LV angiography will be compared with those obtained using echocardiography, and the intra-subject correlation among both LVEF estimates will be analyzed in order to stablish a correlation that may help explain the long and short-term effects of BMMNC.…”

“…To estimate the comparability of data between methods, an approach is to measure LVEF in the same subject by the two methods. This has been done when comparing values using two techniques such as Echo and MPS [8][9][10][11][12][13] ; or when comparing either method with a more invasive procedure such as ventriculography. 9,13,14 Comparability is generally gauged by calculating the significance of a correlation coefficient when data pairs are plotted as a function of each other.…”
