Figure 1 Intended line designs: anteroposterior of a mesh graph of the electroanatomic reconstruction of the right and the left atrium. Multiple dark red dots represent ablation lines. The following lesions were performed in the right atrium: (A) the isthmus line between the tricuspid annulus and the inferior vena cava. (B) The posterior intercaval line. (C) The septal line that begins from the superior vena cava, proceeds to the fossa ovalis, and to the coronary sinus ostium where a circumferential line was performed, and terminates in the inferior vena cava. In the left atrium, a circumferential lesion was placed around the left and right pulmonary veins. In addition, a linear lesion connecting the left circular lesion with the mitral annulus was placed (D). LAO = left anterior oblique.
