- W2128305667 abstract "The aim of this study was to evaluate image quality and accuracy of a new hand-carried ultrasound device, OptiGo (Agilent Technologies) when compared to standard echocardiography in the setting of a focused examination in the assessment of cardiac anatomy and function.One-hundred and twenty-one patients were prospectively enrolled. Image quality and accuracy in assessment of chamber sizes, left ventricular (LV) wall thickness and contractility, right ventricular (RV) function, mitral and aortic leaflet thickening, mitral annular calcification, pericardial effusion and valvular regurgitation were assessed. Two-dimensional (2D) findings were graded on a four-point scale, except for LV function (six-point) and valvular leaflet opening (two-point). Colour Doppler assessment of valvular regurgitation was graded on a seven-point scale. A one-point difference was considered minor; a two or more point difference was considered major. There was no statistically significant difference in image quality between the two devices. For 2D data, the number of total (minor and major) differences between the hand-carried and standard echocardiograph examinations was significantly greater than the inter-observer variability (14.3% vs 10.7%, P< 0.05), however, major differences alone were not statistically different. For the colour Doppler assessment of regurgitation there was a significant difference between the devices for total (minor and major) differences, (40.0% vs 31.8%,P < 0.007) however, the number of major differences is explained by inter-observer variability.Image quality and diagnostic accuracy of the hand-carried device, OptiGo, was adequate for the purpose of performing a focused assessment of a limited number of 2D and Doppler parameters for the evaluation of cardiac anatomy and function." @default.
