Guidewire Ablation within the Coronary Venous System for Epicardial or Intramural Ventricular Arrhythmia: A Preclinical Study of Biophysical Characterization

Figure 4

Example of the gross lesion in ex vivo ablation of 10 mm-tip guidewires at a power setting of 15 w with infusion speed of 2 ml/min for 10, 30, 50, 60, and 90 seconds, respectively (a–e). Ablation of 20 mm-tip guidewire at the similar ablation duration of 10, 30, 50, 60, and 90 seconds (f–j).
