Role of three-dimensional imaging integration in atrial fibrillation ablation

Figure 4 The two surfaces have been superimposed based on the guide provided by the two landmarks. The match of the two surfaces has been further improved with the so-called “surface registration” option, obtaining optimal integration. The accuracy of this process is then checked by verifying the distance between each electroanatomic point and the corresponding site on the computed tomography surface. In this case, all sites in the electroanatomic maps are marked by a green dot, which identifies the distance between the two surfaces as < 5 mm.
