- (1) L : the normalized distance of the vortex ring center from the RV/LV apex (normalized by the RV long axis length which defined as the line from the mid of the annulus (i.e.TV or MV) to the apex of the ventricle) (2) Orientation: the angle between the vortex's fitting plane and the RV/LV long axis (3) CI: the ratio between the short axis to the long axis diameter of the ring (s): The parameter was significantly different (p < 0.05) in ventricle's A-filling vortex rings compared to E-filling vortex rings.
