Supports radial strain for detecting regional LV dysfunction on echo; leaves open incremental value over visual assessment in practice.
Does myocardial strain and strain rate calculated from 2D echocardiography by automatic frame-by-frame tracking accurately detect regional left ventricular function abnormalities compared to cMRI in patients?
Frame-by-frame tracking of acoustic markers in 2D echocardiography provides accurate, reproducible quantitative assessment of regional systolic LV function comparable to cMRI.
