Schematic profile of a radiofrequency lesion. (A) Lesion depth was measured from the endocardial surface to the deepest point of the radiofrequency lesion. (B) Maximum lesion diameter was measured at the widest point of the lesion. (C) Depth to maximum lesion diameter was measured from the endocardial surface to the widest point of the lesion. (D) Surface diameter of the radiofrequency lesion.
