12-lead ECG – Wide complex QRS tachycardia, 180/min; RBBB morphology, right-axis deviation suggestive for anterolateral LV exit-site

Figure 2A
Coronary angiogram and FFR measurements – subocclusion of OM 1 (middle segment); 50 % middle LAD stenosis (FFR – 0.73); 50-60 % proximal LCx stenosis (FFR – 0.76)

Figure 2B
Coronary angiogram after implantation of 3 drug-elluting stents (middle LAD, proximal LCx and middle OM1)

Figure 3
Cardiac MRI – Mild LV dilation; LVEF – 43 %; Multiple areas of LGE along the middle third of antero-lateral and lateral wall

Multimodal image integration. Right: Fusion between MDCT and LGE-CMR PSI Map (ADAS 3D Software). Left: Integration with EAM (Biosense – Webster Carto 3 Navigation System)

Figure 5
Substrate-based RF ablation targeting conduction channels (CC) identified on fusion imaging concordant with fractionated and late potentials on EAM

Figure 6
EGMs before and after RF ablation showing fragmented potential abolition at the conducting channel entry
