Figure 3 A: Ultra-high-density 3-dimensional activation map of the tachycardia shows figure-of-eight intra-atrial reentrant tachycardia with the slow conduction zone at the anastomosis line between the left atrial appendage and the left pulmonary veins. Radiofrequency catheter ablation was performed along the ridge between the left atrial appendage and the left pulmonary veins. The red-filled circles indicate ablation lesions. B: Ultra-high-density 3-dimensional voltage map during tachycardia shows the low and borderline voltage along the anastomosis lines (dotted lines).
