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.
