Analysis of the patients with non-ipsilateral matching
27 patients with contralateral IA underwent further analysis (Figure
6A). Ablation attempts were effective in 19/27 (70.4%) patients (Figure
6B). But IA success rate was only 10/27 (37.0%). By measuring the
distances from EVA sites to PVVJ, 5.7mm was the maximum for
contralateral IA to be effective, indicating the largest heating area of
ablation attempts. Using the distance of 5.7mm, excluding 1 patient with
PA origin, effective ablation was estimated 54/60(90.0%) by the
supravalvular strategy and 52/60(86.7%) by the subvalvular strategy in
the total patients. (Figure 6C).
