Change in LA volume index after CA
The changes in the LA volume index before and 6 months after CA or
the last cardioversion in both groups are shown in Figure 2.
Only 2 patients in the short-term continuation group were in AF rhythm
at follow-up. The others were in sinus rhythm. In comparison to
baseline, the LA volume index was significantly decreased at follow up
in both groups (both p<0.01). There were no significant
differences in the LA volume index between the two groups at the
follow-up. Based on the cutoff value (≥ 15% reduction in LA
volume index), the percentage of patients who achieved LA reverse
remodeling was comparable between patients in the short-term
continuation group (46/63, 73%) and long-term continuation group
(19/32, 59%) (p=0.24).
