Figure 5 (A) Posteroanterior view showing color-coded preablation electroanatomical voltage map of the left atrium and pulmonary veins using a CARTO RMT integration system. (B) Post-ablation electroanatomical map with encircled lesions around all targeted pulmonary veins and the mitral isthmus line. Note atrial electrograms before (A, arrow) and after ablation (B). No potentials were recorded inside encircled lesions (arrow). The mitral isthmus ablation line is evident. (C) A mesh anatomical map is shown. (D) Red points depicted on fluoroscopic views indicate ablation points sent from the CARTO RMT integration system. Blue line shown on both fluoroscopic images represents the base for target control navigation on Navigant.
