Feature-Tracking in TAVR patients. Feature-Tracking of AS patients before and after TAVR. Myocardial contours were traced in end-diastole (ED) as well as end-systole (ES) of long axis 2- and 4-chamber views (CV) and short axis orientations. T1 mapping and scar analyses using late-gadolinium-enhancement (LGE) sequences were performed in short axis images as well. Graphs of global ventricular strain parameters (longitudinal [GLS] and circumferential [GCS]) over a whole cardiac cycle are depicted. Dotted lines indicate strain performance before intervention, solid lines represent strain characteristics 1 year after TAVR
