LVS PVC eliminated with bipolar ablation between the GCV and left coronary cusp after failed standard ablation using CARTO (Biosense Webster, Diamond Bar, CA). A: Clinical PVC morphology. B: Activation map with an ablation catheter at the point of earliest activation. C: Pacemapping from the point of earliest activation with a 98.2% match in the PASO^TM module. D: Earliest activation time (44 ms) with the sensing catheter located in the left coronary cusp. E: Fluoroscopic view of the location of the ablation catheters during bipolar ablation. F: Electroanatomic map showing the location of the ablation catheters during bipolar ablation. G: Suppression of PVCs during bipolar ablation delivery Abbreviations as in Figure 2.
