Key result
Visually guided laser ablation for drug-refractory atrial fibrillation resulted in 82.3% of paroxysmal AF patients remaining free of AF at 1 year, and 75% at 48 months.
Observational (n=194)
No
Visually guided laser ablation is safe and effective for achieving durable pulmonary vein isolation with good long-term freedom from atrial fibrillation in both paroxysmal and persistent AF patients.

Supports durable PVI with VGLA in PAF; hypothesis-generating for long-term efficacy, needs randomized confirmation.
ediva et al. (2014) conducted an observational in Paroxysmal or persistent atrial fibrillation (n=194). Visually guided laser ablation was evaluated on Freedom from atrial fibrillation at 1 year (paroxysmal AF group). Visually guided laser ablation for drug-refractory atrial fibrillation resulted in 82.3% of paroxysmal AF patients remaining free of AF at 1 year, and 75% at 48 months.
