Conclusions
Even in the context of an LSI guided ablation strategy, use of lower or
higher powers might lead to different lesion sizes. Use of higher powers
might be preferrable in case of catheter instability or in case of
difficulty to increase CF. Different LSI targets might be needed,
depending on power and mean CFV used, to prevent unnecessary ablation
and reduce the risk of collateral damage. Incorporating indicators of
catheter stability, like CFV, in the LSI formula could improve the
predictive value of LSI for lesion size. Larger studies with clinical
outcomes are required to confirm the clinical relevance of these
findings.
