Figure 6 Example of a successful ablation of idiopathic ventricular tachycardia from the epicardium through a percutaneous pericardial access. (A) Shown are both unipolar (Abl uni) and bipolar (Abl bi) electrograms from the ablation catheter positioned at the LVOT. (B and C) Epicardial electroanatomic activation maps during frequent premature ventricular complexes are shown. Red color indicates the earliest activation time. The dark red dots represent the successful ablation site (ABL). (D and E) Radiograms show the successful ablation site in relation to the left coronary arteries. Other abbreviations as in Figures 2 and 3.
