The aim of the study was to evaluate the prevalence of supraventricular tachycardia (SVT) inducibility in patients referred for AF ablation and to evaluate the effects of SVT ablation on AF recurrences.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and results<\/jats:title><jats:p>249 patients (mean age: 54\u2009\u00b1\u200914 years) referred for paroxysmal AF ablation were studied. In all patients, only AF relapses had been documented in the clinical history. 47 patients (19%; mean age: 42\u2009\u00b1\u200911 years) had inducible SVT during the electrophysiological study and underwent an ablation targeted only at SVT suppression. Ablation was successful in all 47 patients. The ablative procedures were: 11 slow-pathway ablations for atrioventricular nodal re-entrant tachycardia; 6 concealed accessory pathway ablations for atrioventricular re-entrant tachycardia; 17 focal ectopic atrial tachycardia ablations; 13 with only one arrhythmogenic pulmonary vein. No recurrences of SVT were observed during the follow-up (32\u2009\u00b1\u200918 months). 4 patients (8.5%) showed recurrence of at least one episode of AF. Patients with inducible SVT had less structural heart disease and were younger than those without inducible SVT.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>A significant proportion of candidates for AF ablation are inducible for an SVT. SVT ablation showed a preventive effect on AF recurrences. Those patients should be selected for simpler ablation procedures tailored only to the triggering arrhythmia suppression.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fcvm.2023.1115328","type":"journal-article","created":{"date-parts":[[2023,7,14]],"date-time":"2023-07-14T01:47:08Z","timestamp":1689299228000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":13,"title":["Long-Term Follow-Up In Paroxysmal Atrial Fibrillation Patients With Documented Isolated Trigger"],"prefix":"10.3389","volume":"10","author":[{"given":"Zefferino","family":"Palam\u00e0","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio Gianluca","family":"Robles","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matteo","family":"Paoletti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martina","family":"Nesti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ermenegildo","family":"De\u00a0Ruvo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"Scar\u00e0","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessio","family":"Borrelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriele","family":"De\u00a0Masi\u00a0De\u00a0Luca","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariano","family":"Rillo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leonardo","family":"Cal\u00f2","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"Cavarretta","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvio","family":"Romano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luigi","family":"Sciarra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,7,13]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"373","DOI":"10.1093\/eurheartj\/ehaa612","article-title":"ESC Scientific Document Group. 2020 ESC Guidelines for the diagnosis and management of atrial fibrillation developed in collaboration with the European Association for Cardio-Thoracic Surgery (EACTS): The task force for the diagnosis and management of atrial fibrillation of the European Society of Cardiology (ESC) Developed with the special contribution of the European Heart Rhythm Association (EHRA) of the ESC","volume":"42","author":"Hindricks","year":"2021","journal-title":"Eur Heart J"},{"key":"B2","doi-asserted-by":"publisher","first-page":"659","DOI":"10.1056\/NEJM199809033391003","article-title":"Initiation of atrial fibrillation by ectopic beats originating in the pulmonary veins","volume":"339","author":"Ha\u00efssaguerre","year":"1998","journal-title":"N Engl J Med"},{"key":"B3","doi-asserted-by":"publisher","first-page":"310","DOI":"10.2174\/157340312803760721","article-title":"Triggers and anatomical substrates in the genesis and perpetuation of atrial fibrillation","volume":"8","author":"S\u00e1nchez-Quintana","year":"2012","journal-title":"Curr Cardiol Rev"},{"key":"B4","doi-asserted-by":"publisher","first-page":"753","DOI":"10.1016\/0002-8703(93)90167-8","article-title":"Initiation of atrial fibrillation in the wolff-parkinson-white syndrome: the importance of the accessory pathway","volume":"125","author":"Wathen","year":"1993","journal-title":"Am Heart J"},{"key":"B5","doi-asserted-by":"publisher","first-page":"681","DOI":"10.1016\/S0002-9149(96)00842-9","article-title":"Atrial fibrillation induced by atrioventricular nodal reentrant tachycardia","volume":"79","author":"Brugada","year":"1997","journal-title":"Am J Cardiol"},{"key":"B6","doi-asserted-by":"publisher","first-page":"9295326","DOI":"10.1155\/2022\/9295326","article-title":"Tailoring the ablative strategy for atrial fibrillation: a state-of-the-art review","volume":"2022","author":"Palam\u00e0","year":"2022","journal-title":"Cardiol Res Pract"},{"key":"B7","doi-asserted-by":"publisher","first-page":"1707","DOI":"10.1093\/europace\/euq327","article-title":"How many atrial fibrillation ablation candidates have an underlying supraventricular tachycardia previously unknown?
