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.
