Echocardiogram identified a 156\u2009mm\u2009Hg left ventricular outflow tract gradient with provocation, indicating hypertrophic cardiomyopathy with left ventricular outflow obstruction\u2014confirmed with MRI and angiogram. An alcohol septal ablation was planned but due to communication of the second septal perforator with the right ventricle and a wire-induced mid-left anterior descending artery dissection, alcohol septal ablation was not performed. Instead, a covered stent was placed in the mid-left anterior descending artery covering the origins of the third and fourth septal perforators. The left ventricular outflow tract gradient decreased from 90 to 30\u2009mm\u2009Hg with provocation and her symptoms improved. Follow-up showed a left ventricular outflow tract gradient of 35\u2009mm\u2009Hg with provocation and decreased symptoms.<\/jats:p>","DOI":"10.1136\/bcr-2022-250929","type":"journal-article","created":{"date-parts":[[2022,12,19]],"date-time":"2022-12-19T11:16:04Z","timestamp":1671448564000},"page":"e250929","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Effective treatment of hypertrophic cardiomyopathy with left ventricular outflow tract obstruction using a covered stent"],"prefix":"10.1136","volume":"15","author":[{"given":"Devon","family":"Pekas","sequence":"first","affiliation":[{"name":"School of Medicine and Health Sciences, University of North Dakota, Grand Forks, North Dakota, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adya","family":"Chawda","sequence":"additional","affiliation":[{"name":"Interventional Cardiology, Sanford Health Bismarck, Bismarck, North Dakota, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nayan","family":"Desai","sequence":"additional","affiliation":[{"name":"Interventional Cardiology, Sanford Health Bismarck, Bismarck, North Dakota, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,12,19]]},"reference":[{"key":"2025082708022736000_15.12.e250929.1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.287.10.1308"},{"key":"2025082708022736000_15.12.e250929.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jchf.2017.09.011"},{"key":"2025082708022736000_15.12.e250929.3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcmg.2016.05.003"},{"key":"2025082708022736000_15.12.e250929.4","doi-asserted-by":"crossref","first-page":"655","DOI":"10.1056\/NEJMra1710575","article-title":"Clinical course and management of hypertrophic cardiomyopathy","volume":"379","author":"Maron","year":"2018","journal-title":"N Engl J Med Overseas Ed"},{"key":"2025082708022736000_15.12.e250929.5","doi-asserted-by":"crossref","DOI":"10.3390\/jcm9103062","article-title":"Alcohol septal ablation versus septal myectomy treatment of obstructive hypertrophic cardiomyopathy: a systematic review and meta-analysis","volume":"9","author":"Byty\u00e7i","year":"2020","journal-title":"J Clin Med"},{"key":"2025082708022736000_15.12.e250929.6","doi-asserted-by":"crossref","first-page":"190","DOI":"10.1002\/clc.23113","article-title":"Alcohol septal ablation vs myectomy for symptomatic hypertrophic obstructive cardiomyopathy: systematic review and meta-analysis","volume":"42","author":"Osman","year":"2019","journal-title":"Clin Cardiol"},{"key":"2025082708022736000_15.12.e250929.7","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000068035.52761.71"},{"key":"2025082708022736000_15.12.e250929.8","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000111127.49988.79"},{"key":"2025082708022736000_15.12.e250929.9","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.106.631689"},{"key":"2025082708022736000_15.12.e250929.10","first-page":"73","article-title":"Pericardium-covered stent for septal myocardial ablation in hypertrophic obstructive cardiomyopathy","volume":"47","author":"Gaspar","year":"1999","journal-title":"Catheter Cardiovasc Interv"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2022-250929","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T15:02:31Z","timestamp":1756306951000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2022-250929"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,12]]},"references-count":10,"journal-issue":{"issue":"12","published-online":{"date-parts":[[2022,12,19]]},"published-print":{"date-parts":[[2022,12]]}},"alternative-id":["10.1136\/bcr-2022-250929"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2022-250929","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2022,12]]}}}
