Figure 4

Discontinuous linear lesion. A: Endocardial view of isolated right atrial preparation with important structures labelled. Red dashed line indicates ablation line. Yellow outline indicates optical field of view. Black square pulse represents pacing location. B: Endocardial view of right atrial preparation post TTC staining. White arrow indicates unabalated myocardium. C: Activation map before ablation. D: Activation map post ablation. Lesion line is not continuous. Small gap allows excitation to proceed through ablation line.
