A: Electroanatomical voltage map of the right ventricle (RV) showing an inferobasal scar with abnormal potentials inside the scar. B: Swan-Ganz catheter positioned on the outflow tract (left) and on the basal portion of the RV (right) showing atrial pressure on that position, confirming that the scar on electroanatomical mapping was related to the atrialized portion of the RV. Ablation was performed in the border of the scar, leading to isolation of the scar confirmed by an entrance block (C, top) and exit block (C, bottom) after pacing maneuvers.
