Ablation procedure
PVI was successfully completed in all patients, using Carto 3 in 479
(94%), Rhythmia in 20 (4%) and Ensite NavX in 11 (2%). The majority
of cases underwent radiofrequency catheter ablation. Cryoballoon
ablation was performed in 23 cases (5%).
Details of the initial and additional procedures are listed in Table 2.
In the initial procedure, BOX isolation and LVA ablation were more
frequently performed in group B and C. With the additional treatments, a
higher percentage of PVI was completed in group C and there was more LVA
ablation in groups B and C. In group A, SVC isolation was performed more
frequently. There was no difference in the number of times ABL was
performed among the three groups.
