Fig. 7From: Cardiac fluid dynamics meets deformation imagingChanges from PRE- and POST-CRT or the ratio between systolic flow force components during systole, measure by root mean square (RMS). Responder patients (1–3) present an evident improvement of force alignment with therapy as indicated by the increase longitudinal-to-transversal ratio. Non-responder patients (4–6) display no or minor improvement in force alignmentBack to article page
