It is therefore hypothesized that in an end-stage heart failure population, atrial fibrillation is of great relevance and that interventional therapy is crucial to preventing further progression, especially with the aim of avoiding a heart transplant. In this paper, we describe the clinical presentation of atrial fibrillation and its management in a real end-stage heart failure cohort of patients actively waiting on a heart transplant through EUROTRANSPLANT. Methods: A total of 577 patients have been actively listed for heart transplant in our clinic. Of these, we examined all patients who were actively listed by the key date of 31 December 2024. Patients already treated by assist devices such as the left-ventricular assist device and high-urgency listed patients were excluded, as were minors and patients in need of simultaneous transplantation of other organs in addition to the heart. Results: Thirty-one patients were included in our analysis. In this cohort, 18 patients (58%) had no diagnosis of atrial fibrillation or atrial flutter. A total of 13 patients (42%) presented with atrial fibrillation or flutter: 3\/13 (23%) paroxysmal, 8\/13 (62%) persistent, 1\/13 (8%) permanent atrial fibrillation, and 1\/13 (8%) atrial flutter. Moreover, 9\/13 (69%) patients with atrial fibrillation had been diagnosed during evaluation and before the active listing period for heart transplant. Only three patients developed atrial fibrillation during the active listing period (two with atypical atrial flutter, one with atrial fibrillation). In those three patients, rhythm control could be achieved: the patient with new-onset atrial fibrillation was treated by pulmonary vein ablation, and in the two patients with newly diagnosed atypical atrial flutter, electrical cardioversion was performed. Conclusions: In our real end-stage heart failure cohort, more than half of the patients do not have atrial fibrillation. Patients diagnosed with atrial fibrillation often receive their diagnosis before they are listed for heart transplant. However, atrial fibrillation is not a common cause of clinical worsening while actively waiting on a heart transplant.<\/jats:p>","DOI":"10.3390\/jcdd13050194","type":"journal-article","created":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T06:50:01Z","timestamp":1777618201000},"page":"194","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Clinical Relevance of Atrial Fibrillation in End-Stage Heart Failure Patients Actively Waiting on Heart Transplant"],"prefix":"10.3390","volume":"13","author":[{"given":"Magda","family":"Haum","sequence":"first","affiliation":[{"name":"Department of Medicine I, LMU University Hospital, 81377 Munich, Germany"},{"name":"DZHK (German Center for Cardiovascular Research), Partner Site Munich Heart Alliance, 80636 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ulrich","family":"Grabmaier","sequence":"additional","affiliation":[{"name":"Department of Medicine I, LMU University Hospital, 81377 Munich, Germany"},{"name":"DZHK (German Center for Cardiovascular Research), Partner Site Munich Heart Alliance, 80636 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonia","family":"Kellnar","sequence":"additional","affiliation":[{"name":"Department of Medicine I, LMU University Hospital, 81377 Munich, Germany"},{"name":"DZHK (German Center for Cardiovascular Research), Partner Site Munich Heart Alliance, 80636 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7212-9191","authenticated-orcid":false,"given":"Christoph","family":"M\u00fcller","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, LMU University Hospital, 81377 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Korbinian","family":"Lackermair","sequence":"additional","affiliation":[{"name":"Department of Medicine I, LMU University Hospital, 81377 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heidi","family":"Estner","sequence":"additional","affiliation":[{"name":"Department of Medicine I, LMU University Hospital, 81377 Munich, Germany"},{"name":"DZHK (German Center for Cardiovascular Research), Partner Site Munich Heart Alliance, 80636 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3599","DOI":"10.1093\/eurheartj\/ehab368","article-title":"2021 ESC Guidelines for the diagnosis and treatment of acute and chronic heart failure","volume":"42","author":"McDonagh","year":"2021","journal-title":"Eur.
