Session 4.4 - Case & Discussion: Seeing the Source: Advanced Mapping and ICE in PVC Ablation
This session, led by Fermin Garcia (Philadelphia, US), presents a challenging case in Seeing the Source Advanced Mapping and ICE in PVC Ablation, showing how advanced intracardiac echo and mapping uncovered a basal lateral left ventricular epicardial scar that explained failed endocardial RF and PFA attempts and ultimately guided successful epicardial ablation, while also defining an “inaccessible” fat-covered lateral LV region that may underlie some VT ablation failures. In discussion, Usha Tedrow (Boston, US) highlights persistent barriers in PVC ablation, including limited mapping access, epicardial fat and inadequate lesion depth, while Andre d’Avila (Boston, US) stresses the variability of epicardial fat, the importance of pre-imaging and alternative strategies such as vein or alcohol ablation; Fermin Garcia (Philadelphia, US) and moderator Devi Nair (Jonesboro, US) conclude that improving ICE image quality is essential and that future AI tools will only be useful if built on high-fidelity imaging integrated with 12-lead ECG interpretation.
