The acute effects and follow-up after the visually guided laser balloon ablation for atrial fibrillation treatment

We read with great interest, the article by Ucer et al. about the effects of intravenous adenosine after pulmonary vein (PV) isolation for atrial fibrillation (AF) using the visually guided laser balloon ablation (VGLA).1 We are thankful to them for taking the initiative to consolidate the available evidence, sharing their experience and valuable insights. It was worthwhile noticing that a fixed (??) dose of 18 mg of adenosine was used, at least 20 min after the ablation of PVs for all 25 patients to achieve dormant conduction. Among total 102 PVs, 99 (97% of the ablated PVs) were successfully …
