Effects of Trypanocidal Treatment on Echocardiographic Parameters in Chagas Cardiomyopathy and Prognostic Value of Wall Motion Score Index: A BENEFIT Trial Echocardiographic Substudy
2019, Journal of the American Society of EchocardiographyCitation Excerpt :LV wall motion was analyzed using a 16-segment polar map, and segmental scores were assigned for normal wall motion (1), hypokinesia (2), akinesia (3), and dyskinesia (4). Segmental scores were added and divided by 16, providing an individual wall motion score index (WMSI), with an LV WMSI of 1 being normal and an LV WMSI of 4 ideally reflecting dyskinesia of all segments.14 Binary categorizations for the presence or absence of RV wall motion abnormalities and for mural thrombus were made (yes or no).
Quantifying "normalized" regional left ventricular contractile function in ischemic coronary artery disease
2015, Journal of Thoracic and Cardiovascular SurgeryValidation of a novel modified wall motion score for estimation of left ventricular ejection fraction in ischemic and non-ischemic cardiomyopathy
2012, European Journal of RadiologyCitation Excerpt :However, these methods continue to require proprietary software, and are based heavily upon geometric assumptions that are not met in all patients [13], and do not take into account regional wall motion abnormalities sub-optimally represented within these views. The use of segmental wall motion scoring for the estimation of LVEF has been previously explored by several echocardiography studies [13–19]. These studies, all employing the scoring system currently endorsed by the ASE [4], were modest in size with the largest being performed in 243 consecutive patients undergoing both transthoracic echocardiography and radionuclide angiography (RNA) [13].
Reliability of Visual Assessment of Global and Segmental Left Ventricular Function: A Multicenter Study by the Israeli Echocardiography Research Group
2010, Journal of the American Society of EchocardiographyCitation Excerpt :Vermes et al13 also showed large interobserver variability (the left ventricle divided into 7 segments, 15 subjects, 2 readers, and 2 categories). An intraobserver difference of 7% was reported by Badano et al14 (the left ventricle divided into 16 segments, 105 subjects, only 2 readers, and 5 categories), similar to the 5.6 ± 2.9% of segments in our study that were assigned different scores by the same reader in duplicate readings. Hoffmann et al15 addressed the issue of variability in the detection of WM as a byproduct of a multicenter study on dobutamine stress echocardiography (which requires the ability to identify new WM abnormalities) and reported a κ coefficient of only 0.37 for interobserver variability (150 subjects, 5 readers, and 4 categories), although with better imaging, a κ coefficient of 0.55 was achieved.16
