Article Title: Prognostic Value of Right Ventricular Strains Using Novel Three-Dimensional Analytical Software in Patients With Cardiac Disease
doi: 10.3389/fcvm.2022.837584
Figure Lengend Snippet: Two representative cases of three-dimensional (3D) right ventricular (RV) analysis using ReVISION software: One case of normal RV function (3D RVEF: 49%, A–C ) and another case of severe RV dysfunction (3D RVEF: 28%, D–F ). Transparent light-yellow and light-green represents the end-diastolic endocardial boundary, and darker yellow and darker green represents the end-systolic endocardial boundary. Gray lines indicate contours used for 3D RV global circumferential strain (RVGCS) (A,D) , and 3D RV global longitudinal strain (RVGLS) (B,E) assessment, respectively. Light-blue segmental areas and their change from end-diastole to end-systole represent the rationale behind area strain calculations [3D RV global area strain (RVGAS) is calculated using entire RV endocardial areas, C,F ].
Article Snippet: For RV analysis, we used commercially available 3D speckle tracking software (4D RV function 3, TomTec Imaging system, Unterschleissheim, Germany) and ReVISION software (Argus Cognitive, Inc., Lebanon, New Hampshire, USA, www.revisionmethod.com ).
