Comparison of baseline characteristics
Complete bidirectional conduction block of all four PVs was achieved in
all patients. Among the 190 patients enrolled, 21 (11%) experienced AF
recurrence during the follow-up period. The clinical characteristics of
the enrolled patients are shown in Table 1. There were no significant
differences between the two groups in echocardiographic parameters,
including LA dimension; 12-lead electrocardiographic parameters;
underlying diseases; medications; CHADS2 score; and CA
procedure performed.
