Figure 1. (A) Coronary angiography before ablation. (B) Activation map of the clinical ventricular tachycardia (VT 1). Tags on the map denote ablation sites. (C) Coronary angiography after ablation demonstrating an occluded left anterior descending artery (LAD) (arrow). (D) Three-dimensional cardiac computed tomography. Coronary arteries are shown in red. Tags on the map denote ablation sites, which are the same as in panel B. Note the proximity of ablation sites to the LAD.
