a A 12-lead ECG of clinical VT. b Left panel: intracardiac EGM at the ablation site within the proximal of MCV. Right panel: ablation catheter positioning during the ablation within the proximal of MCV (small white arrows show the microcatheter positioned in MCV). c Left panel: intracardiac EGM at the successful ablation site showed the earliest ventricular activity of 38 ms preQRS. Right panel: ablation catheter positioning and electro-anatomical mapping showed the successful ablation site (white arrow) at the basal inferior ventricular septum. MCV indicates middle cardiac vein
