Figure 4. Distances from the EVA sites to the PVVJ. The RVOT
was arbitrarily divided by STJ, PVVJ, and longitudinal extensions of PSC
commissures. The dotted line denoted PVVJ. The markers that coincided
with the PVVJ located at the base of PSCs. Y-axis represented the
distance from each EVA site to PVVJ. (A) Circles denoted the EVA sites
in total patients. (B) The triangles denoted the EVA sites in the
patients who had IA success. (C) The crosses denoted the EVA sites in
the patients who had IA failure. The black arrow marked the EVA site in
PA.
Abbreviations: AC=anterior cusp, EVA=earliest ventricular
activating, LC=left cusp, PA=pulmonary artery, PSC=pulmonary sinus cusp,
PVVJ=pulmonary valve-ventricle junction, RC=right cusp, RV=right
ventricle, RVOT=right ventricular outflow tract, STJ=sinotubular
junction.
