Radiofrequency (RF) catheter ablation stands as the favored therapeutic modality for managing recurring CTI-dependent AFL. Intracardiac echocardiography (ICE) has been proposed as a method to reduce radiation exposure during CTI ablation. This study aims to comprehensively compare procedural parameters between ICE-guided CTI ablation and fluoroscopy-only procedures. A total of 370 consecutive patients were enrolled in our single-center retrospective study. In 151 patients, procedures were performed using fluoroscopy guidance only, while 219 patients underwent ICE-guided CTI ablation. ICE guidance significantly reduced fluoroscopy time (73 (36; 175) s vs. 900 (566; 1179) s; p &lt; 0.001), fluoroscopy dose (2.45 (0.6; 5.1) mGy vs. 40.5 (25.7; 62.9) mGy; p &lt; 0.001), and total procedure time (70 (52; 90) min vs. 87.5 (60; 102.5) min; p &lt; 0.001). Total ablation time (657 (412; 981) s vs. 910 (616; 1367) s; p &lt; 0.001) and the time from the first to last ablation (20 (11; 36) min vs. 40 (25; 55) min; p &lt; 0.01) were also significantly shorter in the ICE-guided group. Acute success rate was 100% in both groups, and no major complications occurred in either group. ICE-guided CTI ablation in patients with AFL resulted in shorter procedure times, reduced fluoroscopy exposure, and decreased ablation times, compared to the standard fluoroscopy-only approach.<\/jats:p>","DOI":"10.3390\/jcm12196277","type":"journal-article","created":{"date-parts":[[2023,9,29]],"date-time":"2023-09-29T05:48:13Z","timestamp":1695966493000},"page":"6277","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Intracardiac Echocardiography Guidance Improves Procedural Outcomes in Patients Undergoing Cavotricuspidal Isthmus Ablation for Typical Atrial Flutter"],"prefix":"10.3390","volume":"12","author":[{"given":"Marton","family":"Turcsan","sequence":"first","affiliation":[{"name":"Heart Institute, Medical School, University of Pecs, Ifjusag utja 13, H-7624 Pecs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristof-Ferenc","family":"Janosi","sequence":"additional","affiliation":[{"name":"Heart Institute, Medical School, University of Pecs, Ifjusag utja 13, H-7624 Pecs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dorottya","family":"Debreceni","sequence":"additional","affiliation":[{"name":"Heart Institute, Medical School, University of Pecs, Ifjusag utja 13, H-7624 Pecs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Toth","sequence":"additional","affiliation":[{"name":"Heart Institute, Medical School, University of Pecs, Ifjusag utja 13, H-7624 Pecs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-7716-1281","authenticated-orcid":false,"given":"Botond","family":"Bocz","sequence":"additional","affiliation":[{"name":"Heart Institute, Medical School, University of Pecs, Ifjusag utja 13, H-7624 Pecs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tamas","family":"Simor","sequence":"additional","affiliation":[{"name":"Heart Institute, Medical School, University of Pecs, Ifjusag utja 13, H-7624 Pecs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Kupo","sequence":"additional","affiliation":[{"name":"Heart Institute, Medical School, University of Pecs, Ifjusag utja 13, H-7624 Pecs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2242","DOI":"10.1016\/S0735-1097(00)00982-7","article-title":"Incidence and predictors of atrial flutter in the general population","volume":"36","author":"Granada","year":"2000","journal-title":"J.
