TMVR can trigger acute left ventricular outflow tract (LVOT) obstruction from permanent displacement of the native anterior mitral leaflet toward the left ventricular septum, more often among patients undergoing valve\u2010in\u2010ring and valve\u2010in\u2010MAC procedures. Although acute LVOT obstruction is well described in the literature, there are important additional complications of TMVR related to the length and\/or redundancy of the anterior mitral valve that have been recognized after mitral valve surgery and have not been previously reported in the setting of TMVR. These additional complications include acute mitral regurgitation secondary to prolapsing native leaflet through the TMVR, frozen TMVR leaflet secondary to overhanging native leaflet and late LVOT obstruction in the neo\u2010LVOT secondary to long native leaflet. Preprocedural planning with imaging (echocardiography and computed tomography) and measurement of anterior mitral leaflet length is critical important in understanding the risk for these complications. As transcatheter mitral valve technology proliferates, interactions with the anterior mitral leaflet after TMVR may be more frequent than initially anticipated. We believe that there is no advantage to an intact anterior leaflet and advocate removal or reduction of the leaflet prior to TMVR. \u00a9 2017 Wiley Periodicals, Inc.<\/jats:p>","DOI":"10.1002\/ccd.27054","type":"journal-article","created":{"date-parts":[[2017,5,4]],"date-time":"2017-05-04T11:42:59Z","timestamp":1493898179000},"page":"627-632","source":"Crossref","is-referenced-by-count":30,"title":["Long or redundant leaflet complicating transcatheter mitral valve replacement: Case vignettes that advocate for removal or reduction of the anterior mitral leaflet"],"prefix":"10.1002","volume":"92","author":[{"given":"Adam B.","family":"Greenbaum","sequence":"first","affiliation":[{"name":"Division of Cardiology Center for Structural Heart Disease, Henry Ford Hospital Detroit Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5157-9978","authenticated-orcid":false,"given":"Jose F.","family":"Condado","sequence":"additional","affiliation":[{"name":"Division of Cardiology Emory University School of Medicine, Structural Heart and Valve Center Atlanta Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marvin","family":"Eng","sequence":"additional","affiliation":[{"name":"Division of Cardiology Center for Structural Heart Disease, Henry Ford Hospital Detroit Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stamatios","family":"Lerakis","sequence":"additional","affiliation":[{"name":"Division of Cardiology Emory University School of Medicine, Structural Heart and Valve Center Atlanta Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dee Dee","family":"Wang","sequence":"additional","affiliation":[{"name":"Division of Cardiology Center for Structural Heart Disease, Henry Ford Hospital Detroit Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dennis W.","family":"Kim","sequence":"additional","affiliation":[{"name":"Division of Pediatric Cardiology Emory University School of Medicine, Structural Heart and Valve Center Atlanta Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert J.","family":"Lederman","sequence":"additional","affiliation":[{"name":"Cardiovascular and Pulmonary Branch, Division of Intramural Research National Heart Lung and Blood Institute, National Institutes of Health Bethesda Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaetano","family":"Paone","sequence":"additional","affiliation":[{"name":"Division of Cardiac Surgery Center for Structural Heart Disease, Henry Ford Hospital Detroit Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William W.
