From: A review of current trends in three-dimensional analysis of left ventricular myocardial strain
2D/3D strain analysis in a patient with cardiac amyloidosis. Upper panels show three 2D apical views, a bull’s eye plot of regional longitudinal strain (LS) and corresponding LS curves. Note the preservation of apical LS (apical sparing) with an apical sparing ratio of 3.4. Apical sparing ratio is defined as the average apical LS divided by (the average basal LS + the average middle LS). Lower panels show three 2D apical views extracted from the 3D dataset, a bull’s eye plot of regional LS, and corresponding curves in the same patient. Note the relative preservation of apical LS with an apical sparing ratio of 0.8
