Figure 4 Bipolar Voltage Map of Both Atria in an Anteroposterior Projection and a Posteroanterior Projection in a Patient Who Underwent Randomized Ablation Strategy
In the right atrium, there is no scar and 8% of low-voltage area. In contrast, scar is present around the pulmonary veins at the posterior and inferior left atrium, accounting for 44% of the left atrium surface area and low-voltage area is present at the roof, anterior left atrium, septum, and inferior left atrium, accounting for 39% of the left atrium surface area (A and B). Note that bipolar voltages in the left atrial appendage are  0.5 mV. This patient showed late diastolic mitral flow of 30 cm/s at 3 months after catheter ablation.
