2013, American Journal of CardiologyCitation Excerpt :A net reclassification index was calculated for comparison of measurements.26 The sample size calculation was based on the assumption that the r value of the correlation for LV mass between CMR and 3DE should have a minimum value of 0.82, according to previous studies.8–20 The minimum sample size in each group was calculated to be 18 (power 0.90).
Assessment of left ventricular mass in hypertrophic cardiomyopathy by real-time three-dimensional echocardiography using single-beat capture image
2013, Journal of the American Society of EchocardiographyCitation Excerpt :Furthermore, the CMR method for LV mass assessment is based on the summation of 2D image stacks, but there are gaps between imaging planes, and thus 3D echocardiography may be more accurate in vivo than CMR for determining LV myocardial mass. Multiple-beat RT3DE imaging has already been shown to significantly improve accuracy in LV mass quantification in comparison with 2D approaches, with CMR as a reference, irrespective of geometric assumptions or using manual adjustment for accurate delineation of endocardial and epicardial borders.14-19 These studies included about 20 patients and acquired RT3DE images with four wedged subvolumes and analyzed them offline.
