From: In vitro characterization of radiofrequency ablation lesions in equine and swine myocardial tissue

Measurements to analyse lesion dimensions and calculate the volume are shown on a schematic representation (left) and on a tissue sample of an ablation lesion in equine ventricular myocardium (right). The maximum depth (A), maximum diameter (B), depth at maximum diameter (C) and surface diameter (D) were measured.
