The extent of the localization of arrhythmogenic foci has been described.<\/jats:p>\n <\/jats:sec>\n \n Methods and Results<\/jats:title>\n A 25\u2010year\u2010old male with RAA\u2010AT experienced recurrence after CA and subsequently underwent right atrial appendectomy. Analysis of the excised specimen, including immunostaining, identified a region enriched with hyperpolarization\u2010activated cyclic nucleotide\u2010gated channel 4 but lacking connexin 43. The findings suggest that the presence of sinoatrial\u2010like cells at the site of origin contributed to atrial tachycardia recurrence.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Our case provided the arrhythmogenic entity of RAA\u2010ATs, which elucidated the difficulty of CA.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/jce.16762","type":"journal-article","created":{"date-parts":[[2025,6,12]],"date-time":"2025-06-12T01:43:40Z","timestamp":1749692620000},"page":"2078-2081","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Insight of Focal Atrial Tachycardia From Right Atrial Appendage in a Case of Resistant to Catheter Ablation: Immunohistological Assessment of the Excised Specimen"],"prefix":"10.1111","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-0756-0883","authenticated-orcid":false,"given":"Shintaro","family":"Inaba","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Biology and Medicine Juntendo University Graduate School of Medicine Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7547-891X","authenticated-orcid":false,"given":"Shunsuke","family":"Kuroda","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Biology and Medicine Juntendo University Graduate School of Medicine Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Norihito","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Biology and Medicine Juntendo University Graduate School of Medicine Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minoru","family":"Tabata","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery Juntendo University School of Medicine Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tohru","family":"Minamino","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Biology and Medicine Juntendo University Graduate School of Medicine Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,6,11]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2006.03.058"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/eum264"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2013.10.017"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.1994.tb01170.x"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jjcc.2022.02.008"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.119.007387"}],"container-title":["Journal of Cardiovascular Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jce.16762","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/jce.16762","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jce.16762","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,8]],"date-time":"2026-03-08T14:23:56Z","timestamp":1772979836000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/jce.16762"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,6,11]]},"references-count":6,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2025,8]]}},"alternative-id":["10.1111\/jce.16762"],"URL":"https:\/\/doi.org\/10.1111\/jce.16762","archive":["Portico"],"relation":{},"ISSN":["1045-3873","1540-8167"],"issn-type":[{"value":"1045-3873","type":"print"},{"value":"1540-8167","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,6,11]]},"assertion":[{"value":"2025-02-25","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-05-29","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-06-11","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
