Differences in the impact of the LI drop and lesion size between MiFi and STABLEPOINT
Comparing the 2 different catheters, the % LI rise in the STABLEPOINT was significantly higher than that in the MiFi under all CFs and all contact angles (Supplemental Figures A, B, and C). The values of % LI drop in the STABLEPOINT were significantly higher than those in the MiFi except for under 30 g of CF at 90° and 45° (Supplemental Figures D, E, and F).
Figure 7 shows the correlations between the %LI drop and lesion size for the 2 catheters. The approximate curves were well fitted with a natural logarithm equation on %LI drop vs. maximum lesion width (Figure 7A) and lesion depth (Figure 7B) for both catheters. The absolute values of the LI parameters were different, but the association between the percent changes and lesion sizes were similar between the 2 catheters.
