In this work, authors evaluated the effectiveness and safety of pulmonary vein isolation (PVI) using high-power short duration ablation. The study was conducted in the period from 2021 to 2022 at the City Clinical Hospital No.1 The study included 30 patients. All operations were performed using the navigation system CARTO® 3 version 6. Ablative electrode THERMOCOOL SMARTTOUCH® SF. RFA was performed with AI 400-450 in posterior wall and 500-550 in the anterior wall with power of 50 watts. Results: Efficacy of the procedure was 100% in all patients. Within 6 months, AF recurred in 5 patients (16.67%), first round isolation 29/30 (97%). There were no significant intraoperative complications. The total procedure time was 89±13 min. Conclusions: High-power short duration RFA in patients with atrial fibrillation significantly reduces the operating time, does not increase the incidence of intraoperative complications and is effective in the short term.

Keywords:Atrial fibrillation, ablation index, high power
