Fig. 3From: Impact of left ventricular outflow tract ellipticity on the grading of aortic stenosis in patients with normal ejection fractionBland-Atman plots comparing 2D-echo and CMR measurements of indexed stroke volume (panel a) and of indexed AVA (panel b). On average, 2D-echo underestimated the indexed stroke volume and AVA by 29% compared with CMR Back to article page
