Although AF ablation has become an established treatment for patients with HF, it is usually an elective procedure. Here, we present a case of acute decompensated heart failure (ADHF) exacerbated by refractory AF, which was successfully treated with emergent AF ablation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>A 53-year-old, obese man with a history of myocardial infarction presented to our hospital. Heart function deteriorated with an ejection fraction of 9.8%, and he was repeatedly hospitalized due to worsening HF. This time, the patient was emergently admitted due to ADHF associated with persistent AF. Atrial fibrillation was refractory to electrical cardioversion. Despite optimized medical support, the patient developed haemodynamic collapse and multiple organ failure. Intra-aortic balloon pump (IABP) and mechanical ventilation were initiated in addition to intravenous catecholamines. Emergent AF ablation was performed. Following pulmonary vein isolation, sinus rhythm was restored and the patient's haemodynamic status dramatically improved. The IABP and mechanical ventilation were withdrawn within a few days, and the catecholamine dose was reduced. After cardiac rehabilitation, the patient was discharged.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>Our case suggests that an emergent AF ablation is feasible and effective even in a patient with severe ADHF. An emergent AF ablation could be a therapeutic option to treat a critically unwell patient who has deteriorated due to a vicious cycle of AF and HF.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytab350","type":"journal-article","created":{"date-parts":[[2021,9,4]],"date-time":"2021-09-04T14:15:32Z","timestamp":1630764932000},"source":"Crossref","is-referenced-by-count":5,"title":["Emergent catheter ablation for atrial fibrillation in a patient with acute decompensated heart failure on a mechanical haemodynamic support: a case report"],"prefix":"10.1093","volume":"5","author":[{"given":"Tomoyuki","family":"Tobushi","sequence":"first","affiliation":[{"name":"Division of Cardiology, Japanese Red-Cross Fukuoka Hospital, 3-1-1, Okusu, Minami-ku, Fukuoka, 815-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4683-0328","authenticated-orcid":false,"given":"Takuya","family":"Sakemi","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Japanese Red-Cross Fukuoka Hospital, 3-1-1, Okusu, Minami-ku, Fukuoka, 815-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7900-5784","authenticated-orcid":false,"given":"Nobuhiro","family":"Honda","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Japanese Red-Cross Fukuoka Hospital, 3-1-1, Okusu, Minami-ku, Fukuoka, 815-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0275-7280","authenticated-orcid":false,"given":"Yasushi","family":"Mukai","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Japanese Red-Cross Fukuoka Hospital, 3-1-1, Okusu, Minami-ku, Fukuoka, 815-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2021,9,4]]},"reference":[{"key":"2021120110525302700_ytab350-B1","doi-asserted-by":"crossref","first-page":"417","DOI":"10.1056\/NEJMoa1707855","article-title":"Catheter ablation for atrial fibrillation with heart failure","volume":"378","author":"Marrouche","year":"2018","journal-title":"N Engl J Med"},{"key":"2021120110525302700_ytab350-B2","doi-asserted-by":"crossref","first-page":"373","DOI":"10.1093\/eurheartj\/ehaa612","article-title":"2020 ESC Guidelines for the diagnosis and management of atrial fibrillation developed in collaboration with the European Association for Cardio-Thoracic Surgery (EACTS)","volume":"42","author":"Hindricks","year":"2021","journal-title":"Eur Heart J"},{"key":"2021120110525302700_ytab350-B3","doi-asserted-by":"crossref","first-page":"685","DOI":"10.1016\/j.hrcr.2020.06.017","article-title":"Bailout cryoballoon ablation for hemodynamically unstable atrial fibrillation in patients with decompensated heart failure","volume":"6","author":"Matsuda","year":"2020","journal-title":"HeartRhythm Case Rep"},{"key":"2021120110525302700_ytab350-B4","first-page":"348","article-title":"Atrial fibrillation in acute heart failure: a position statement from the Acute Cardiovascular Care Association and European Heart Rhythm Association of the European Society of Cardiology","volume":"9","author":"Gorenek","year":"2020","journal-title":"Eur Heart J"},{"key":"2021120110525302700_ytab350-B5","doi-asserted-by":"crossref","first-page":"1812","DOI":"10.1056\/NEJMoa1408288","article-title":"Approaches to catheter ablation for persistent atrial fibrillation","volume":"372","author":"Verma","year":"2015","journal-title":"N Engl J Med"},{"key":"2021120110525302700_ytab350-B6","doi-asserted-by":"crossref","first-page":"e50","DOI":"10.1093\/eurheartj\/suaa059","article-title":"Atrial fibrillation ablation in heart failure","volume":"22","author":"Balla","year":"2020","journal-title":"Eur Heart J Suppl"},{"key":"2021120110525302700_ytab350-B7","doi-asserted-by":"crossref","first-page":"49","DOI":"10.1093\/europace\/euaa236","article-title":"Impact of centre volume on atrial fibrillation ablation outcomes in Europe: a report from the ESC EHRA EORP Atrial Fibrillation Ablation Long-Term (AFA LT) Registry","volume":"23","author":"Vassilikos","year":"2021","journal-title":"Europace"},{"key":"2021120110525302700_ytab350-B8","doi-asserted-by":"crossref","first-page":"1070","DOI":"10.1093\/europace\/eut206","article-title":"2013 ESC guidelines on cardiac pacing and cardiac resynchronization therapy: the task force on cardiac pacing and resynchronization therapy of the European Society of Cardiology (ESC).
