LI rise and LI drop at different catheter contact angles
Figures 4A and 4C show the correlation between the catheter contact angle and the LI rise under each CF. The LI values increased as CF increased for both catheters. Regarding the difference in the catheter contact angles, there was no angular dependence for the LI rise under all CFs in the MiFi (Figure 4A). On the other hand, the LI rise at 90° was lower than that at 30° under 5 and 10 g of CF in STABLEPOINT (Figure 4C).
Figures 4B and 4D show the correlation between the catheter contact angle and the LI drop by the RF application under each CF. The LI drop values also increased as the CF increased for both catheters. Regarding the difference in the catheter contact angles, the LI drop at 90° was significantly lower than that at 30° under 10, 20, and 30 g of CF in the MiFi (Figure 4B). Likewise, the LI drop at 90° was significantly lower than that at 30° under 5, 10, 20, and 30 g of CF in STABLEPOINT (Figure 4D).
