In the emergency department, the patient had several runs of ventricular fibrillation treated with defibrillation and amiodarone infusion. Echocardiography revealed reduced ejection fraction with multiple mobile structures attached to the tricuspid valve leaflets. Due to concern for possible endocarditis, the patient was started on broad-spectrum antibiotics. On the following day, a renal ultrasound was performed for acute kidney injury followed by a non-contrast CT scan that revealed an obstructing 21\u2009mm left-sided ureteral stone with pyohydronephrosis. He underwent emergent nephrostomy tube placement. Blood and urine cultures subsequently demonstrated the growth of<jats:italic>Klebsiella oxytoca<\/jats:italic>. A follow-up transoesophageal echocardiogram confirmed multiple mobile, hyperechoic masses consistent with vegetations. The suspected source for the endocarditis was from the pyelonephritis. The patient\u2019s clinical condition improved after a course of intravenous antibiotics and was discharged on oral antibiotics.<\/jats:p>","DOI":"10.1136\/bcr-2018-225352","type":"journal-article","created":{"date-parts":[[2018,9,1]],"date-time":"2018-09-01T12:35:13Z","timestamp":1535805313000},"page":"bcr-2018-225352","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["<i>Klebsiella oxytoca<\/i>tricuspid valve endocarditis in an elderly patient without known predisposing factors"],"prefix":"10.1136","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7489-6968","authenticated-orcid":false,"given":"Waqas","family":"Memon","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melinda","family":"Miller","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zonaira","family":"Shabbir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2018,9,1]]},"reference":[{"key":"2025042706075361000_2018.sep01_1.bcr-2018-225352.1","doi-asserted-by":"publisher","DOI":"10.1128\/CMR.00134-14"},{"key":"2025042706075361000_2018.sep01_1.bcr-2018-225352.2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.293.24.3012"},{"key":"2025042706075361000_2018.sep01_1.bcr-2018-225352.3","doi-asserted-by":"crossref","first-page":"398","DOI":"10.3904\/kjim.2014.29.3.398","article-title":"Native valve endocarditis due to extended spectrum \u03b2-lactamase producing Klebsiella pneumoniae","volume":"29","author":"Jung","year":"2014","journal-title":"Korean J Intern Med"},{"key":"2025042706075361000_2018.sep01_1.bcr-2018-225352.4","doi-asserted-by":"publisher","DOI":"10.1172\/JCI108216"},{"key":"2025042706075361000_2018.sep01_1.bcr-2018-225352.5","doi-asserted-by":"publisher","DOI":"10.1016\/j.gheart.2014.01.002"},{"key":"2025042706075361000_2018.sep01_1.bcr-2018-225352.6","first-page":"1","article-title":"Tricuspid valve endocarditis due to streptococcus bovis in a patient with ventricular septal defect: a rare manifestation\u2014case report and review of the literature","volume":"2017","author":"Pushpakumara","year":"2017","journal-title":"Case Rep Infect Dis"},{"key":"2025042706075361000_2018.sep01_1.bcr-2018-225352.7","first-page":"181","article-title":"Infective endocarditis caused by Klebsiella oxytoca in an intravenous drug user with cancer","volume":"29","author":"Mohamed","year":"2016","journal-title":"Proc"},{"key":"2025042706075361000_2018.sep01_1.bcr-2018-225352.8","doi-asserted-by":"publisher","DOI":"10.1016\/j.jinf.2005.08.015"},{"key":"2025042706075361000_2018.sep01_1.bcr-2018-225352.9","first-page":"1","article-title":"Tricuspid valve endocarditis due to Klebsiella species in a non-intravenous drug user \u2013 a case report and review of current literature","volume":"3","author":"Shidali","year":"2016","journal-title":"Journal of Clinical & Medical Case Reports"},{"key":"2025042706075361000_2018.sep01_1.bcr-2018-225352.10","doi-asserted-by":"crossref","first-page":"776","DOI":"10.3346\/jkms.2014.29.6.776","article-title":"Clinical features of right-sided infective endocarditis occurring in non-drug users","volume":"29","author":"Lee","year":"2014","journal-title":"J Korean Med Sci"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2018-225352","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T13:08:00Z","timestamp":1745759280000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2018-225352"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,9,1]]},"references-count":10,"alternative-id":["10.1136\/bcr-2018-225352"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2018-225352","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,9,1]]}}}
