Results of Ablation
Acute PVI, verified by entrance and exit blocks, was achieved in all patients. In the Non-CF group, additional SVC or PLA isolation were performed in 24 patients (24.7%), while, in the CF group, additional SVC or PLA isolation were performed in 102 patients (34.2%).
Parameters associated with ablation are shown in Table 2. The CF group had a shorter total RF delivery time and smaller amount of RF energy delivered than the Non-CF group. Regarding the post-ablation inflammatory response, the ratio of pre- to post-ablation WBC and the elevation of CRP levels were significantly lower in the CF group than in the Non-CF group.
