Key result
Direct visualization using a novel endoscopic balloon-based laser ablation system successfully isolated 91% of pulmonary veins, achieving a 60% 12-month drug-free freedom from atrial fibrillation.

Hypothesis-generating for visually guided laser balloon PVI; leaves open comparative efficacy versus standard ablation in paroxysmal AF.
Reddy et al. (2009) conducted a cohort in paroxysmal atrial fibrillation (n=30). Endoscopic balloon-based laser ablation system was evaluated on 12-month drug-free rate of freedom from atrial fibrillation. Direct visualization using a novel endoscopic balloon-based laser ablation system successfully isolated 91% of pulmonary veins, achieving a 60% 12-month drug-free freedom from atrial fibrillation.
