Figure 1 : 

(A) Ventricular tachycardia electrocardiogram showing right bundle branch block and left axial deviation aspect. (B) Rest electrocardiogram after ventricular tachycardia showing negative T waves in the lateral leads. (C) Initial magnetic resonance imaging (MRI) short-axis view: first-pass perfusion imaging demonstrated an important perfusion defect in the radiofrequency ablation area. (D, E) Initial MRI short- and long-axis view late gadolinium enhancement (LGE) sequences: no-reflow core was found, surrounded by a ring of LGE next to the posterior papillary muscle. (F) Three months later, MRI first-pass perfusion imaging short-axis view: defect had decreased but not disappeared. (G, H) Three months later, MRI short- and long-axis view LGE sequences: decreased but still present central no-reflow area surrounded by a ring of LGE.
