Figure 2. Pre-Defined Catheter-Tissue Contact Cohorts: A. NTC
Example: ICE image of the LAF catheter (outlined in white) in close
proximity to the tissue surface (dotted yellow). No color change in LI
GUI as impedance change is ≤∆10Ω threshold. B. LTC Example: ICE
image of catheter touching the tissue surface and light green GUI tip
graphic corresponding to light contact. C. HTC Example: ICE
shows some deformation of the spheroid tip while pushing into tissue and
dark green GUI tip graphic corresponding to heavy contact. All lesions
were assigned to one of the three CTC cohorts prior to energy delivery.
