Why the study?
Does Cryothermal or Laser ablation compared to RF ablation result in different left atrial scar burden in patients with atrial fibrillation?
Does Cryothermal or Laser ablation compared to RF ablation result in different left atrial scar burden in patients with atrial fibrillation?
Radiofrequency, cryothermal, and laser ablation for atrial fibrillation produce similar extents of left atrial fibrosis as measured by LGE-MRI at 3 months.

Similar scar burden across modalities; supports equivalence in fibrosis induction while leaving clinical outcome differences open.
Khurram et al. (2015) studied this question.
