Discussion
To the best of our knowledge, the present study is the first to
investigate the performance of both the baseline and injection tool in
assessing PV occlusion with the latest version of KODEX-EPD system. The
major findings of the present study are: i) both tools were able to
accurately assess the degree of PV occlusion in CBA procedure; ii) both
tools could predict the acute cryoablation effect; iii) baseline tool
showed a higher sensitivity, while injection tool showed a higher
specificity.
