Figure 3. RF lesion size measurement.
Figure 3 shows the representative lesion images for each catheter angle
RF application (30 watts, 30 sec, CF = 30 g). MWs, SWs, and LDs were
evaluated for each lesion.
MW = maximum lesion width, SW = surface width, LD = lesion depth, RFCA =
radiofrequency ablation.
Figure 4. Relationship between the catheter contact
angle and the LI rise and LI drop
Figure 4 shows the correlation between the catheter contact angle and LI
rise (4A and 4C) and the LI drop (4B and 4D) under each CF in the MiFi
(upper panel) and the STABLEPOINT (lower panel).
LI = local impedance, CF = contact force.
