RF ablation
SE
The detailed procedure has been described elsewhere.RF ablation will be performed with an open irrigated tip catheter (Thermocool SmartTouch SF, Thermocool SmartTouch; Biosense Webster; TactiCath SE, Flexibility, Abbott). The RF ablation settings will be a power of 30‐50 W, targeting an ablation index of 450–550 for CARTO and a lesion index of 4.0–5.0 for NavX. The power and duration will usually be reduced to 20–25 W for 20 s on the LA posterior wall near the esophagus. Contact force data will be continuously monitored throughout the procedure to achieve at least 10 g (mean) with a vector perpendicular to the tissue and with an upper limit of 50 g.
