Ventricular Tachycardia Originating from Moderator Band: New Perspective on Catheter Ablation

Figure 3

(a) Ablation catheter at the earliest activation site on the MB using fluoroscopy. (b) Electroanatomic mapping showed that the ablation zone (red points) was placed at the site of earliest activation at the middle RV of lower septum. (c) Ablation at the earliest activation site on the MB (red arrow) guiding by TTE; the ablation catheter (yellow arrow) was placed at the septum insertion of MB.
