Imaging characteristics
The mean LA diameter for the total cohort was 4.4 ± 0.7 cm, while the mean LVEF was 55.7 ± 10.1 % (Table 2). Patients undergoing RF ablation had higher LA diameter (4.5 vs. 4.1 cm, p=<0.01) as compared to the CB cohort. There was no significant difference in LVEF between the RF vs. CB cohorts.
