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.
