The electrocardiogram showed narrow QRS tachycardia with a heart rate of 170 bpm. Despite boluses of adenosine and amiodarone perfusion, the patient experienced recurrent supraventricular tachycardia (SVT), leading to cardiogenic shock. Extracorporeal membrane oxygenation was initiated for hemodynamic support. An electrophysiologic study identified an accessory pathway in a coronary sinus diverticulum. Successful radiofrequency ablation was performed, resulting in clinical and left ventricular ejection fraction improvement. This case highlights the challenges in managing incessant SVT with cardiogenic shock and complex ablation procedures.<\/jats:p>","DOI":"10.4081\/monaldi.2025.3385","type":"journal-article","created":{"date-parts":[[2025,6,10]],"date-time":"2025-06-10T07:27:44Z","timestamp":1749540464000},"source":"Crossref","is-referenced-by-count":1,"title":["Refractory supraventricular tachycardia from a coronary sinus diverticulum leading to cardiogenic shock: a challenging ablation case"],"prefix":"10.4081","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-8753-4615","authenticated-orcid":true,"given":"Marta Catarina","family":"Bernardo","sequence":"first","affiliation":[{"name":"Department of Cardiology, Tr\u00e1s-os-Montes and Alto Douro Local Health Unit, Vila Real"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabel","family":"Moreira","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Tr\u00e1s-os-Montes and Alto Douro Local Health Unit, Vila Real"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catarina","family":"Ribeiro Carvalho","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Tr\u00e1s-os-Montes and Alto Douro Local Health Unit, Vila Real"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Pedro","family":"Guimar\u00e3es","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Tr\u00e1s-os-Montes and Alto Douro Local Health Unit, Vila Real"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu\u00eds","family":"Ad\u00e3o","sequence":"additional","affiliation":[{"name":"Department of Cardiology, S\u00e3o Jo\u00e3o Local Health Unit"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00edlvia","family":"Le\u00e3o","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Tr\u00e1s-os-Montes and Alto Douro Local Health Unit, Vila Real"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sofia","family":"Silva Carvalho","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Tr\u00e1s-os-Montes and Alto Douro Local Health Unit, Vila Real"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Il\u00eddio","family":"Moreira","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Tr\u00e1s-os-Montes and Alto Douro Local Health Unit, Vila Real"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2549","published-online":{"date-parts":[[2025,6,10]]},"reference":[{"key":"57667","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(96)00592-X"},{"key":"57668","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2024.03.416"},{"key":"57669","doi-asserted-by":"publisher","DOI":"10.1016\/j.hroo.2022.10.006"},{"key":"57670","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehz467"},{"key":"57671","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrcr.2018.11.008"},{"key":"57672","doi-asserted-by":"publisher","DOI":"10.1007\/s00392-018-1367-3"},{"key":"57673","doi-asserted-by":"publisher","DOI":"10.1111\/anec.13100"}],"container-title":["Monaldi Archives for Chest Disease"],"original-title":[],"link":[{"URL":"https:\/\/www.monaldi-archives.org\/macd\/article\/download\/3385\/2086","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.monaldi-archives.org\/macd\/article\/download\/3385\/2086","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T00:02:06Z","timestamp":1791417726000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.monaldi-archives.org\/macd\/article\/view\/3385"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,6,10]]},"references-count":7,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2026,9,7]]}},"URL":"https:\/\/doi.org\/10.4081\/monaldi.2025.3385","relation":{},"ISSN":["2532-5264","1122-0643"],"issn-type":[{"value":"2532-5264","type":"electronic"},{"value":"1122-0643","type":"print"}],"subject":[],"published":{"date-parts":[[2025,6,10]]}}}
