Representative bipolar voltage amplitude maps for the Orion catheter (top row), the Lasso catheter (middle row), and Mifi catheter (bottom row) for the three established cutoffs 0.1–1.5 mV, 0.2–1.5 mV, and 0.5–1.5 mV. The scar area in red decreases from the Orion over the Lasso to the Mifi catheter for every scar cutoff (0.1 mV, 0.2 mV, 0.5 mV).
