This retrospective study included participants with paroxysmal AF who received pulmonary vein isolation ablation in a single centre in Germany [1]. The analysis included 410 participants who received either pulsed-field ablation (n=201) or high-power short-duration radiofrequency (n=209; using the ablation index and CLOSE protocol). Outcomes were assessed over a 12-month follow-up period and included 5-day Holter-ECG assessments at 3, 6 and 12 months after ablation. Prof. Nico Reinsch (Alfried-Krupp-Hospital Rüttenscheid, Germany) presented the 1-year results.
Pulsed-field ablation versus high-power short-duration radiofrequency ablation led to significantly shorter procedural time (median 61 vs 125 min; P<0.001), left atrium dwell time (median 46 vs 110 min; P<0.001) but longer fluoroscopy time (median 16 vs 4 min; P<0.001). The incidence of procedural complications was similar between the two groups (2.9% vs 6.2%; P=0.159). After 12 months of follow-up, 85% of participants with pulsed-field ablation and 79% of participants with high-power short-duration radiofrequency ablation were free from any atrial tachyarrhythmia (P=0.160).
In this single-centre experience, pulmonary vein isolation using pulsed-field ablation showed “significantly shorter procedure times; however, fluoroscopy time and dosage were higher,” said Prof. Reinsch. Furthermore, “there was no significant difference in safety profiles between groups, and arrhythmia-free survival was similar after 1 year of follow-up”.
