Figure 6. Distribution of the EVA sites in patients who
had non-ipsilateral-matching IA. (A) The circles denoted the EVA sites
with IA success and failure. (B) The circles denoted the EVA sites with
ineffective and effective ablation during IA. The black arrow marked the
farthest EVA site to PVVJ (-5.7mm) with effective ablation. (C) The
circles denoted the EVA sites in total patients. The EVA site (black
arrow) in PA was excluded. The dashed box denoted the EVA sites located
from -5.7mm to 10.0mm, estimating that 54/60(90.0%) patients could have
effective ablation by supravalvular strategy. The dotted box denoted the
EVA sites from RVOT to +5.7mm above PVVJ, estimating that the
subvalvular strategy could have effective ablation in 52/60(86.7%)
patients.
Abbreviations: EVA=earliest ventricular activating, IA=initial
ablation, PA=pulmonary artery, PVVJ=pulmonary valve-ventricle junction.
