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.
