Figure Lengend Snippet: Accessory pathway ablation within 2 seconds of pulsed field ablation (PFA). A: Intracardiac electrogram that demonstrates loss of retrograde activation of the right atrium following the application of PFA. B: Three-dimensional electroanatomic map of the right atrium after ablation in the left anterior oblique view. The PFA catheter position is depicted ( orange arrowhead ). The purple area depicts normal voltage/healthy myocardial tissue, and the red area depicts the ablated region ( red arrowhead ).
Article Snippet: With 3-dimensional electroanatomic mapping (Carto 3, Biosense Webster, Irvine, CA), a concealed right free wall accessory pathway localized at the 11- to 12-o’clock position on the tricuspid valve annulus was demonstrated.
Techniques: Activation Assay
