Key result
Novel 2D echo method matches 3D accuracy for LV mass and improves reproducibility over 1D.
Why the study?
Increased left ventricular mass predicts adverse cardiovascular events, but conventional echocardiographic methods are limited by poor reproducibility and accuracy.
Does a novel 2D echocardiography method improve the reproducibility and accuracy of left ventricular mass quantification compared to conventional methods?
Population
85 participants with various left ventricular geometries

Absolute Event Rate: 2% vs 2%
A novel 2D echocardiographic method for quantifying left ventricular mass provides better reproducibility and accuracy than conventional 1D methods, with accuracy comparable to 3D echocardiography.
Kristensen et al. (2022) conducted a cohort in Patients scheduled for echocardiography with various left ventricular geometries (n=85). Novel 2D echocardiography method for left ventricular mass quantification vs. 3D echocardiography and 1D echocardiography (CMR as reference) was evaluated on Accuracy of left ventricular mass quantification compared to cardiac magnetic resonance (mean difference in grams). A novel 2D echocardiographic method for quantifying left ventricular mass showed similar accuracy to 3D echocardiography (mean difference 2 ± 50 g) and better reproducibility than 1D methods.
