A 78-year-old woman with estrogen receptor\/progesterone receptor-positive, HER2-negative breast cancer who developed acute dyspnea and paroxysmal nocturnal dyspnea after her ninth weekly paclitaxel infusion. Cardiac evaluation revealed new-onset atrial fibrillation, elevated N-terminal pro-B-type natriuretic peptide, and multimodal imaging findings consistent with restrictive cardiomyopathy, including bi-atrial enlargement, severe valvular regurgitation, and myocardial fibrosis on cardiac magnetic resonance imaging. She had no prior cardiac history, and alternative etiologies were excluded. The temporal association with paclitaxel strongly implicated drug-induced cardiotoxicity. Proposed mechanisms include microtubule disruption, mitochondrial injury, calcium dysregulation, and potential toxicity from the solvent Cremophor EL. Prompt cessation of paclitaxel and initiation of heart failure therapy led to clinical improvement. This case highlights the need for vigilance for cardiac toxicities in chemotherapy patients with cardio-oncology collaboration.<\/jats:p>","DOI":"10.4103\/ijp.ijp_764_25","type":"journal-article","created":{"date-parts":[[2026,3,2]],"date-time":"2026-03-02T07:00:15Z","timestamp":1772434815000},"page":"150-152","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":2,"title":["Rare manifestation of paclitaxel-induced cardiotoxicity: A case of restrictive cardiomyopathy in an elderly breast cancer patient"],"prefix":"10.4103","volume":"58","author":[{"given":"Kumar","family":"Masum","sequence":"first","affiliation":[{"name":"Department of Pharmacy Practice, Karnataka College of Pharmacy, Bengaluru, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandeep","family":"Srinivas","sequence":"additional","affiliation":[{"name":"Department of Pharmacy Practice, Karnataka College of Pharmacy, Bengaluru, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Balakeshwa","family":"Ramaiah","sequence":"additional","affiliation":[{"name":"Department of Pharmacy Practice, Karnataka College of Pharmacy, Bengaluru, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,3,2]]},"reference":[{"key":"R1-20260302","doi-asserted-by":"crossref","first-page":"1004","DOI":"10.1056\/NEJM199504133321507","article-title":"Paclitaxel (taxol)","volume":"332","author":"Rowinsky","year":"1995","journal-title":"N Engl J Med"},{"key":"R2-20260302","doi-asserted-by":"crossref","first-page":"2231","DOI":"10.1016\/j.jacc.2009.02.050","article-title":"Cardiovascular complications of cancer therapy: Incidence, pathogenesis, diagnosis, and management","volume":"53","author":"Yeh","year":"2009","journal-title":"J Am Coll Cardiol"},{"key":"R3-20260302","doi-asserted-by":"crossref","first-page":"665","DOI":"10.2165\/00003088-200342070-00005","article-title":"Pharmacological effects of formulation vehicles: Implications for cancer chemotherapy","volume":"42","author":"Ten","year":"2003","journal-title":"Clin Pharmacokinet"},{"key":"R4-20260302","doi-asserted-by":"crossref","first-page":"488","DOI":"10.1016\/j.jcmg.2012.11.013","article-title":"Noncontrast T1 mapping for the diagnosis of cardiac amyloidosis","volume":"6","author":"Karamitsos","year":"2013","journal-title":"JACC Cardiovasc Imaging"},{"key":"R5-20260302","first-page":"1173","article-title":"Multi-modality imaging in the assessment of cardiovascular toxicity in the cancer patient","volume":"11","author":"Plana","year":"2018","journal-title":"J Am Coll CardiolImg"}],"container-title":["Indian Journal of Pharmacology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/ijp.ijp_764_25","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,26]],"date-time":"2026-08-26T19:43:14Z","timestamp":1787773394000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/ijp.ijp_764_25"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3]]},"references-count":5,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.4103\/ijp.ijp_764_25","relation":{},"ISSN":["0253-7613","1998-3751"],"issn-type":[{"value":"0253-7613","type":"print"},{"value":"1998-3751","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,3]]},"assertion":[{"value":"2025-07-28","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-12-10","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
