Ablation index (AI) is the novel tool which helps to achieve transmural lesions during catheter ablation. However, benefit of this protocol in the reduction of myocardial injury is still not known.<\/jats:p><\/jats:sec><jats:sec><jats:title>Purpose<\/jats:title><jats:p>The aim of the study was to compare myocardial injury during catheter ablation using standard and AI protocol.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>To the analysis we included 24 patients with paroxysmal atrial fibrillation, who underwent radiofrequency catheter PVI using CARTO system (Biosense Webster, Inc). In all patients cardiac troponin I (cTnI) levels were assessed before and 24\u00a0hours after the procedure. In 12 patients PVI was performed using continuous applications (dragging technique) and in 12 patients during PVI ablation AI protocol was implemented. To unify analyzed groups, we excluded patients with additional ablation lines (including line separating ipsilateral pulmonary veins).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In analyzed group mean age was 59.3\u00a0\u00b1\u00a07.7\u00a0years and 18 (75%) patients were male.

Trend in shorter total x\u2010ray time was observed in AI group compared with dragging group (8.6\u00a0\u00b1\u00a05.4 vs. 5.3\u00a0\u00b1\u00a03.2\u00a0min.; <jats:italic>P<\/jats:italic>\u00a0=\u00a0.093) with no differences in total procedure time (146.3\u00a0\u00b1\u00a028.9 vs. 153.2\u00a0\u00b1\u00a037.1\u00a0min.; <jats:italic>P<\/jats:italic>\u00a0=\u00a0.616). Twenty\u2010four hours after the PVI procedure cTnI levels were significantly lower in AI group than in dragging group (1.984\u00a0\u00b1\u00a00.644 vs. 3.369\u00a0\u00b1\u00a01.818\u00a0ng\/mL; <jats:italic>P<\/jats:italic>\u00a0=\u00a0.026), with no difference in mean baseline cTnI levels (0.004\u00a0\u00b1\u00a00.006 vs. 0.015\u00a0\u00b1\u00a00.032\u00a0ng\/mL; <jats:italic>P<\/jats:italic>\u00a0=\u00a0.304).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Presented study revealed that compared with standard, continuous applications, AI protocol implementation results in reduction of myocardial injury during catheter PVI in patients with paroxysmal atrial fibrillation.<\/jats:p><\/jats:sec>","DOI":"10.1002\/joa3.12424","type":"journal-article","created":{"date-parts":[[2020,9,2]],"date-time":"2020-09-02T13:48:03Z","timestamp":1599054483000},"page":"1039-1044","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Reduction of myocardial necrosis using \u201cCLOSE\u201d protocol during pulmonary vein isolation\u2014Preliminary results from ACTIVE\u2010AF trial"],"prefix":"10.1002","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8519-3707","authenticated-orcid":false,"given":"Micha\u0142","family":"Peller","sequence":"first","affiliation":[{"name":"1st.
