Lesion components listed for the CTI as a whole and stratified according
to anatomical site. Significant p values (<0.05) are
highlighted in bold.
Across all procedures, a total of 682 ablation lesions were delivered
(IVC: 206, Mid CTI: 242, V: 234) and 6,187,716 data points extracted.
The number of ablation lesions per procedure ranged from 5 to 44. For
the whole CTI, there was a strong correlation between peak AI and mean
impedance drop (figure 1 - R2=0.89,
p<0.0001). However, analysis by anatomical site demonstrated
significant variation in this relationship (figure 2).
