Long-term follow-up of patients treated with laser balloon for atrial fibrillation: A high volume center experience with the first- and second-generation laser balloon.

LB showed a high efficacy and acceptable safety, with numerically lower complication rates with the second-generation LB. Procedure and fluoroscopy times were shorter with LB2. Overall, 73.7% of patients were free from AF at 1-year, with comparable results among both generations.
