In this case, we present a patient with severe mitral valve regurgitation due to a perforation in the anterior mitral leaflet detected 4\u2005months after an operation for relief of subaortic stenosis. A 10-year-old male patient who was operated for subvalvular aortic stenosis in another clinic was admitted to our hospital, and transthoracic echocardiography revealed severe mitral valve regurgitation due to a defect that was demonstrated at the anterior valve leaflet. The perforated area at the mitral valve zone A1 was repaired with a PTFE patch. The patient was successfully operated for the mitral valve perforation and the postoperative course was uneventful. In our case, the perforation in the anterior mitral leaflet implies a possible implementation of inappropriate surgical technique which necessitated a second surgical intervention after the initial operation.<\/jats:p>","DOI":"10.1136\/bcr-2014-204463","type":"journal-article","created":{"date-parts":[[2014,5,23]],"date-time":"2014-05-23T06:32:29Z","timestamp":1400826749000},"page":"bcr2014204463","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Severe mitral regurgitation due to anterior mitral leaflet perforation after surgical treatment of discrete subaortic stenosis"],"prefix":"10.1136","volume":"2014","author":[{"given":"Arda","family":"Ozyuksel","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Surgery, Medipol University, Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ozgur","family":"Yildirim","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Medicana International Hospital, Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ibrahim","family":"Onsel","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Medicana International Hospital, Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mehmet Salih","family":"Bilal","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Medicana International Hospital, Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2014,5,23]]},"reference":[{"key":"2025082802364306000_2014.may23_1.bcr2014204463.1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5223(99)70286-2"},{"key":"2025082802364306000_2014.may23_1.bcr2014204463.2","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(02)05027-0"},{"key":"2025082802364306000_2014.may23_1.bcr2014204463.3","doi-asserted-by":"publisher","DOI":"10.1017\/S104795110200029X"},{"key":"2025082802364306000_2014.may23_1.bcr2014204463.4","first-page":"785","article-title":"Intraoperative transesophageal echocardiographic demonstration of mitral leaflet tear following resection of a subaortic membrane","volume":"8","author":"Rattes","year":"1992","journal-title":"Can J Cardiol"},{"key":"2025082802364306000_2014.may23_1.bcr2014204463.5","doi-asserted-by":"publisher","DOI":"10.1177\/0218492310361528"},{"key":"2025082802364306000_2014.may23_1.bcr2014204463.6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8191.2006.00230.x"},{"key":"2025082802364306000_2014.may23_1.bcr2014204463.7","first-page":"79","article-title":"The pathology of mitral papillary muscles in mitral regurgitation associated with discrete subaortic stenosis","volume":"2","author":"Allwork","year":"1988","journal-title":"Am J Cardiovasc Pathol"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2014-204463","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T09:36:48Z","timestamp":1756373808000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2014-204463"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,5,23]]},"references-count":7,"alternative-id":["10.1136\/bcr-2014-204463"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2014-204463","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,5,23]]}}}
