Abstract

AIMS: The availability of a true 3D dataset provides an opportunity for automation of left ventricular (LV) and left atrial (LA) measurements. Although manual and automated measurements of 3D volumes are known to correlate, the variance is an important parameter for the individual patient. The reasons for discrepancies remain unexplained. We hence aim to explain the disagreement between automated and manual LV and LA volumes. METHODS AND RESULTS: A total of 355 patients underwent standard clinical echo, with offline analysis in both fully- (Heart Model, Philips) and semiautomated (3DQ-Adv, Philips) assessment of routine indices of LV and LA function and shape. Each image was classified accor..
