Key result
Robot-assisted minimally invasive left atrial isolation using microwave energy achieved electrical isolation in all 6 canines, but histologic transmurality was inconsistent.
No takes yet. Share an insight, caveat, or question.
Inconsistent transmurality despite electrical success in canines warrants caution for translation; leaves open optimization of robotic microwave ablation.
Smith et al. (2006) studied Atrial fibrillation (ablation feasibility) (n=6). Robot-assisted left atrial isolation using flexible microwave probe was evaluated on Feasibility of left atrial isolation and reliability of exit block pacing to confirm transmurality. Robot-assisted minimally invasive left atrial isolation using microwave energy achieved electrical isolation in all 6 canines, but histologic transmurality was inconsistent.
