Table 1 Correlation of source to destination distribution of thromboemboli with hemodynamic descriptors for extent of vorticity (ratio of Q-criteria between LVAD driven flow and baseline flow without LVAD), extent of wall shear stress (ratio of TAWSS between LVAD driven flow and baseline flow without LVAD), extent of positive helicity and negative helicity (ratio of +ve/-ve local normalized helicity between LVAD driven flow and baseline flow without LVAD). Thromboembolus distribution is represented here combined across all embolus sizes considered. All correlation estimated using Pearson’s linear correlation coefficients.
