Consequently, he underwent epicardial mapping with adjuvant AI\u2010enabled CT images with the creation of a three\u2010dimensional model, which demonstrated a midmyocardial scar. Fractionated potentials were noted during mapping in this region, and entrainment suggested an inner loop. Interestingly, pacing showed two different QRS morphologies identical to his previously ablated VTs with a long stim\u2010QRS at this region. Epicardial ablation carried on during the VT successfully terminated it, but the VT remained inducible and required endocardial ablation to make it noninducible.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This case emphasizes the importance of recognizing possible three\u2010dimensional VT circuits in some patients and the need to understand and target mid\u2010myocardial substrate from both the endocardium and epicardium to achieve the elimination of the VT circuits.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jce.16370","type":"journal-article","created":{"date-parts":[[2024,7,16]],"date-time":"2024-07-16T11:24:03Z","timestamp":1721129043000},"page":"1888-1892","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Recurrent monomorphic ventricular tachycardia in a patient with myocarditis\u2014Importance of understanding and targeting midmyocardial anatomic substrate"],"prefix":"10.1111","volume":"35","author":[{"given":"Usha B.","family":"Tedrow","sequence":"first","affiliation":[{"name":"Cardiac Arrhythmia Center, Division of Cardiovascular Medicine, Department of Medicine Harvard Medical School, Brigham and Women's Hospital Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Uyanga","family":"Batnyam","sequence":"additional","affiliation":[{"name":"Cardiac Arrhythmia Center, Division of Cardiovascular Medicine, Department of Medicine Harvard Medical School, Brigham and Women's Hospital Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolina","family":"Hoyos","sequence":"additional","affiliation":[{"name":"Cardiac Arrhythmia Center, Division of Cardiovascular Medicine, Department of Medicine Harvard Medical School, Brigham and Women's Hospital Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6420-8669","authenticated-orcid":false,"given":"Jorge E.","family":"Romero","sequence":"additional","affiliation":[{"name":"Cardiac Arrhythmia Center, Division of Cardiovascular Medicine, Department of Medicine Harvard Medical School, Brigham and Women's Hospital Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,7,16]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2018.11.024"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2020.01.036"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/jce.12565"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.113.000089"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2014.02.012"}],"container-title":["Journal of Cardiovascular Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jce.16370","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,11,19]],"date-time":"2024-11-19T11:51:53Z","timestamp":1732017113000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/jce.16370"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,7,16]]},"references-count":5,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2024,9]]}},"alternative-id":["10.1111\/jce.16370"],"URL":"https:\/\/doi.org\/10.1111\/jce.16370","archive":["Portico"],"relation":{},"ISSN":["1045-3873","1540-8167"],"issn-type":[{"value":"1045-3873","type":"print"},{"value":"1540-8167","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,7,16]]},"assertion":[{"value":"2024-04-18","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-07-01","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-07-16","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
