To the best of our knowledge, no cases have been reported in infants. We present the case of a 2\u2010month\u2010old male who developed RVPM\u2010VT and subsequently underwent successful catheter ablation while on extracorporeal membrane oxygenation (ECMO). Due to the risk of air entry through the sheath from ECMO suction, catheter exchange was performed in a water\u2010filled tray. Pace mapping was utilized to accurately localize the VT origin, followed by ablation using an irrigated catheter, which effectively delivered the necessary power to ablate the RVPM. The VT was successfully terminated post\u2010ablation, with no recurrence observed.<\/jats:p>","DOI":"10.1111\/pace.70057","type":"journal-article","created":{"date-parts":[[2025,9,17]],"date-time":"2025-09-17T16:01:52Z","timestamp":1758124912000},"page":"1285-1290","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Successful Catheter Ablation Under ECMO for Fatal Ventricular Tachycardia from RV Papillary Muscle in an Infant"],"prefix":"10.1111","volume":"48","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-3330-569X","authenticated-orcid":false,"given":"Shigehito","family":"Baba","sequence":"first","affiliation":[{"name":"Department of Pediatrics Niigata University Medical and Dental Hospital  Niigata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aya","family":"Miyazaki","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiology and Department of Adult Congenital Heart Disease Seirei Hamamatsu General Hospital  Shizuoka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sou","family":"Otsuki","sequence":"additional","affiliation":[{"name":"Department of Cardiology Niigata University Medical and Dental Hospital  Niigata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuichi","family":"Shiraishi","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery Niigata University Medical and Dental Hospital  Niigata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kei","family":"Nishiyama","sequence":"additional","affiliation":[{"name":"Advanced Emergency and Critical Care Center Niigata University Medical and Dental Hospital  Niigata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2404-1128","authenticated-orcid":false,"given":"Akihiko","family":"Saitoh","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Niigata University Medical and Dental Hospital  Niigata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,9,17]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2010.01.040"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/jce.13505"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/jce.12478"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.3389\/fped.2022.740230"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.113.000973"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/euu365"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(99)00105-9"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2014.05.010"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2019.04.002"}],"container-title":["Pacing and Clinical Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pace.70057","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/pace.70057","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pace.70057","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,16]],"date-time":"2026-03-16T07:08:30Z","timestamp":1773644910000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/pace.70057"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,9,17]]},"references-count":9,"journal-issue":{"issue":"11","published-print":{"date-parts":[[2025,11]]}},"alternative-id":["10.1111\/pace.70057"],"URL":"https:\/\/doi.org\/10.1111\/pace.70057","archive":["Portico"],"relation":{},"ISSN":["0147-8389","1540-8159"],"issn-type":[{"value":"0147-8389","type":"print"},{"value":"1540-8159","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,9,17]]},"assertion":[{"value":"2025-04-12","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-09-12","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-09-17","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
