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).
