Table 3 Parameters calculated by SD, SH and Echo respectively in both subgroups. The bold showed that for the subgroup with rESV >17mL, the LVEF and ESV values were not significantly different between the SH reconstruction protocol and Echo, whereas the SD reconstruction protocol and Echo had a statistically significant difference
