Workup showed newly reduced left ventricular ejection fraction with global hypokinesis (20%) and restrictive physiology. Positive technetium pyrophosphate scan was suspicious for TTR amyloid while serological workup revealed a monoclonal gammopathy. Cardiac MRI was contraindicated given remote brain aneurysm clip. Given clinical suspicion for cardiac sarcoidosis and divergent non-invasive workup, endomyocardial biopsy was performed which showed non-necrotising granulomas consistent with cardiac sarcoidosis. She was started on steroids with clinical improvement. Cardiac sarcoidosis is a challenging clinical diagnosis, particularly in patients without extracardiac manifestations. This case highlights the importance of a detailed and thorough workup of non-ischaemic cardiomyopathy and being cognizant of infiltrative disease as it can change patient management and outcomes.<\/jats:p>","DOI":"10.1136\/bcr-2020-237530","type":"journal-article","created":{"date-parts":[[2021,2,9]],"date-time":"2021-02-09T15:16:08Z","timestamp":1612883768000},"page":"e237530","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Cardiac sarcoidosis masquerading as ventricular tachycardia storm: a challenging diagnosis"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9377-881X","authenticated-orcid":false,"given":"William","family":"Aitken","sequence":"first","affiliation":[{"name":"Department of Cardiology, Jackson Memorial Hospital\/University of Miami Miller School of Medicine, Miami, Florida, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6409-7070","authenticated-orcid":false,"given":"Darren","family":"Tsang","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Jackson Memorial Hospital\/University of Miami Miller School of Medicine, Miami, Florida, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandra","family":"Chaparro","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Jackson Memorial Hospital\/University of Miami Miller School of Medicine, Miami, Florida, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7134-7325","authenticated-orcid":false,"given":"Devika","family":"Kir","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Jackson Memorial Hospital\/University of Miami Miller School of Medicine, Miami, Florida, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2021,2,9]]},"reference":[{"key":"2025082802391416000_14.2.e237530.1","doi-asserted-by":"crossref","first-page":"1041","DOI":"10.1002\/ehf2.12511","article-title":"Diagnostic performance of imaging investigations in detecting and differentiating cardiac amyloidosis: a systematic review and meta-analysis","volume":"6","author":"Brownrigg","year":"2019","journal-title":"ESC Heart Fail"},{"key":"2025082802391416000_14.2.e237530.2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCIMAGING.112.000132"},{"key":"2025082802391416000_14.2.e237530.3","doi-asserted-by":"publisher","DOI":"10.1093\/ehjci\/jew082"},{"key":"2025082802391416000_14.2.e237530.4","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.116.021612"},{"key":"2025082802391416000_14.2.e237530.5","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.114.011522"},{"key":"2025082802391416000_14.2.e237530.6","doi-asserted-by":"crossref","first-page":"1136","DOI":"10.1007\/s12350-016-0658-1","article-title":"Isolated cardiac sarcoidosis: a focused review of an under-recognized entity","volume":"25","author":"Okada","year":"2018","journal-title":"J Nucl Cardiol"},{"key":"2025082802391416000_14.2.e237530.7","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCIMAGING.113.000867"},{"key":"2025082802391416000_14.2.e237530.8","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2005.01.047"},{"key":"2025082802391416000_14.2.e237530.9","doi-asserted-by":"publisher","DOI":"10.2967\/jnumed.111.090662"},{"key":"2025082802391416000_14.2.e237530.10","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2014.03.043"},{"key":"2025082802391416000_14.2.e237530.11","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.1988.00380030168027"},{"key":"2025082802391416000_14.2.e237530.12","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9343(82)90564-2"},{"key":"2025082802391416000_14.2.e237530.13","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2020.04.022"},{"key":"2025082802391416000_14.2.e237530.14","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCRESAHA.117.310982"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2020-237530","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T09:39:25Z","timestamp":1756373965000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2020-237530"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,2]]},"references-count":14,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2021,2,9]]},"published-print":{"date-parts":[[2021,2]]}},"alternative-id":["10.1136\/bcr-2020-237530"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2020-237530","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,2]]}}}
