Relationship between ER and PV Reconnection
Among 157 patients with ER, 74 patients underwent repeat RFCA for LR (Non-CF: 32 [59.3%]; FTI: 34 [44.2%]; AI: 8 [28.6%]). Patients without ER were excluded from the analysis. Reconnection of any PV was observed in 93.8%, 70.6%, and 25% of patients in the Non-CF, FTI, and AI group, respectively (Figure 5). Patients who underwent AI-guided ablation were less likely to have PV reconnection than those who underwent FTI-guided ablation.
