We present the case of a 46\u2010year\u2010old woman with fatigue, shortness of breath, and edema, who was found to have thrombocytopenia, elevated cardiac biomarkers, and hypereosinophilia (2.96\u2009k\/uL). Cardiac MRI revealed hypertrophic cardiomyopathy, right ventricular hypertrophy, and a restrictive filling pattern, raising suspicion for L\u00f6ffler endocarditis. Despite initial corticosteroid and diuretic treatment, she was readmitted with persistent symptoms. This case highlights the diagnostic imaging and treatment challenges with corticosteroid therapy, to control eosinophilic infiltration and prevent irreversible cardiac damage. L\u00f6ffler endocarditis should be considered in the imaging differential diagnosis of unexplained heart failure.<\/jats:p>","DOI":"10.1155\/cric\/5307648","type":"journal-article","created":{"date-parts":[[2026,8,17]],"date-time":"2026-08-17T07:29:11Z","timestamp":1786951751000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Rare Cause of Restrictive Cardiomyopathy: A Case Report of L\u00f6ffler Endocarditis"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-4967-3781","authenticated-orcid":false,"given":"Jose L.","family":"Diz Ferre","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1231-8329","authenticated-orcid":false,"given":"Edward G.","family":"Soltesz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8565-2811","authenticated-orcid":false,"given":"Agostina","family":"Fava","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,17]]},"reference":[{"key":"e_1_2_14_1_2","doi-asserted-by":"publisher","DOI":"10.3389\/fcvm.2022.970446"},{"key":"e_1_2_14_2_2","doi-asserted-by":"publisher","DOI":"10.2147\/JIR.S458692"},{"key":"e_1_2_14_3_2","volume-title":"Diseases of the Myocardium and Endocardium - ClinicalKey","author":"ClinicalKey","year":"2025"},{"key":"e_1_2_14_4_2","volume-title":"Eosinophilic Syndromes - ClinicalKey","author":"ClinicalKey","year":"2024"},{"key":"e_1_2_14_5_2","volume-title":"StatPearls","author":"Mubarik A.","year":"2025"},{"key":"e_1_2_14_6_2","volume-title":"Hypereosinophilic Syndromes: Treatment - UpToDate","author":"UpToDate","year":"2026"},{"key":"e_1_2_14_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.case.2019.10.008"},{"key":"e_1_2_14_8_2","doi-asserted-by":"publisher","DOI":"10.33963\/kp.15084"}],"container-title":["Case Reports in Cardiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/cric\/5307648","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1155\/cric\/5307648","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/cric\/5307648","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T11:56:53Z","timestamp":1789646213000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/cric\/5307648"}},"subtitle":[],"editor":[{"given":"Satabdi","family":"Datta Choudhury","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"editor"}]}],"short-title":[],"issued":{"date-parts":[[2026,1]]},"references-count":8,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026,1]]}},"alternative-id":["10.1155\/cric\/5307648"],"URL":"https:\/\/doi.org\/10.1155\/cric\/5307648","archive":["Portico"],"relation":{},"ISSN":["2090-6404","2090-6412"],"issn-type":[{"value":"2090-6404","type":"print"},{"value":"2090-6412","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1]]},"assertion":[{"value":"2025-09-25","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-13","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-08-17","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"5307648"}}
