Arrhythmia mechanisms included AVNRT (14%), manifest WPW (21%), high\u2010risk WPW without SVT (5%), concealed pathway AVRT (26%), AFL (12%), AT (14%), and VT (7%). Two patients had both AVNRT and AVRT. Acute success was achieved in all cases without fluoroscopy or acute complications. Over a median 48\u2010month follow\u2010up, three patients had recurrences: one with WPW and Ebstein anomaly, one with ASD\/PLSVC and concealed pathway, and one with dual arrhythmia substrates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Zero\u2010fluoroscopy ablation of arrhythmias in select patients with mild moderate or great complexity CHD is feasible, safe, and effective, offering high acute success and low recurrence while eliminating radiation exposure.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/joa3.70225","type":"journal-article","created":{"date-parts":[[2025,11,18]],"date-time":"2025-11-18T04:30:23Z","timestamp":1763440223000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Zero Fluoroscopy Ablation of Arrhythmias in Patients With Congenital Heart Disease"],"prefix":"10.1002","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5785-2429","authenticated-orcid":false,"given":"Shailendra","family":"Upadhyay","sequence":"first","affiliation":[{"name":"School of Medicine University of Connecticut  Farmington Connecticut USA"},{"name":"Connecticut Children's  Hartford Connecticut USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-0136-1852","authenticated-orcid":false,"given":"Jenna","family":"Schermerhorn","sequence":"additional","affiliation":[{"name":"Children's Mercy Hospital  Kansas City Missouri USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Whitney","family":"Fairchild","sequence":"additional","affiliation":[{"name":"Connecticut Children's  Hartford Connecticut USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jamie","family":"Bopp","sequence":"additional","affiliation":[{"name":"Connecticut Children's  Hartford Connecticut USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irfan","family":"Warsy","sequence":"additional","affiliation":[{"name":"School of Medicine University of Connecticut  Farmington Connecticut USA"},{"name":"Connecticut Children's  Hartford Connecticut USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,11,17]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/eut082"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cjca.2013.02.016"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacadv.2024.100863"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10840\u2010022\u201001173\u20105"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2016.08.014"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10840\u2010018\u20100467\u20103"},{"issue":"3","key":"e_1_2_10_8_1","first-page":"290","article-title":"Catheter Ablation to Treat Supraventricular Arrhythmia in Children and Adults With Congenital Heart Disease: What we Know and Where we Are Going","volume":"16","author":"Thomas P.
