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

Figure 6

An example of a guidewire ablation lesion. (a) Gross lesion located at the distal segment of GCV 10 days postablation. (b) Histology examination showed a well-demarcated lesion around the ablation vessel via Masson’s trichrome staining (MT, 1×). (c) Junction of ablation lesion and normal myocardium (note: necrosis tissue was partly replaced by fibrosis (MT, 5×)).
