Conclusions
From our results, lesion distance and impedance drop determined the
acute PVR in the SAE and the segments other than SAE, respectively, in
USM-guided HPSD-PVI. This strategy could be improved with the guidance
of impedance drop and lesion distance, allowing for reduction in total
amount of RF time and energy as compared with existing HPSD strategy
while maintaining an acceptable late outcome.
