Name of journal: The international journal of cardiovascular imagingAbstract: CONCLUSION: With current HHUD, an averagely experienced operator can accurately bedside visual estimate the LVEF. This may facilitate the incorporation of this technology in daily clinical practice improving the management of patients. Copyright © 2023.

However, this technology has not been rigorously evaluated. The aim of this study was to explore the correlation and the agreement between the LVEF (Left Ventricular Ejection Fraction) visually assessed by a moderately experienced sonographer using an HHUD compared to the routine LVEF assessment performed at the Echocardiography Laboratory.RESULTS: The mean age of the patients was 69.9 +/- 12.5 years. There were 47 females (39.2%). The R-squared was r 0.94 (p < 0.0001) and the ICC was 0.93 (IC 95% 0.91-0.95, p <= 0.0001). The Bland-Altman plot showed limits of agreement (LOA): Upper LOA 10.61 and Lower LOA - 8.95. The overall agreement on the LVEF assessment when it was stratified as "normal" or "reduced" was 89.1%, with a kappa of 0.77 (p < 0.0001). When the LVEF was classified as "normal", "mildly reduced", "moderately reduced", or "severely reduced," the kappa was 0.77 (p < 0.0001). The kappa between the HHUD EC and the comprehensive EC for the detection of RWMAs in the territories supplied by the LAD, LCX and RCA was 0.85, 0.73 and 0.85, respectively.All authors: Teira Calderon A, Levine M, Ruisanchez C, Serrano D, Catoya S, Llano M, Lerena P, Cuesta JM, Fernandez-Valls M, Gonzalez Vilchez F, de la Torre Hernandez JM, Garcia-Garcia HM, Vazquez de Prada JAFiscal year: FY2024 Digital Object Identifier:
