2. Figure 1
Delayed enhanced magnetic resonance imaging. Short axis view of the basal left ventricle of a patient with nonischemic cardiomyopathy. There is intramural delayed enhancement in the basal septum (arrows). This patient had pleomorphic premature ventricular complexes, and ablation was ineffective in this patient.

3. Figure 2
A, left: Delayed enhanced magnetic resonance imaging in a patient with apical transmural scar. Long-axis view demonstrating apical scar (arrows). The site of origin of the targeted premature ventricular complex (PVC) is a transmural scar located in the left ventricular apex. The patient’s PVC was successfully ablated in the apical scar. A, right: Short-axis view close to the apex showing transmural delayed enhancement (arrows). B, left: Ultrasound image, long-axis view showing the left ventricular apex. Arrow indicates site of origin of the targeted PVC. B, middle: Activation map of the left ventricle during PVCs. The earliest site was in the left ventricular apex (arrow indicates site of origin of the mapped PVC). B, right: Left ventricular voltage map indicating an apical scar. The site of origin of the PVC is indicated by the arrow and is within the low-voltage area of the scar. The location of the mitral valve annulus (MVA) and the left ventricular apex is indicated. C: Twelve-lead ECG of the patient with couplets at the site of origin in the left ventricular apex. Activation time at the site of origin was –22 ms.
