Fig. 2From: Impact of left ventricular outflow tract ellipticity on the grading of aortic stenosis in patients with normal ejection fractionBland-Altman plots comparing 2D-echo and CMR measurements of the left ventricular outflow tract (LVOT) anterior-posterior diameters and cross-sectional area. On average, 2D-echo underestimated the LVOT area by 29% compared with CMR Back to article page
