LVOTO is a known complication of mitral valve surgery. A 38-year-old female patient with increasing dyspnoea after mitral valve replacement was referred to our centre. Echocardiography showed a strut of the bioprosthetic heart valve protruding into the left ventricular outflow tract. However, the diagnosis of a LVOTO was difficult based on echocardiography alone. Therefore, we fabricated a physical model of the left ventricular outflow tract, the mitral valve, the aortic valve and the left ventricle. With this physical model in hand, we were able to visualize the LVOTO and to discuss potential therapeutic options. Moreover, we were able to plan the subsequent redo surgery in detail using the model. This case shows the benefit of 3D printing technologies for surgeons and patients, not only for analysis, but also during the decision-making and pre-operative planning process.<\/jats:p>","DOI":"10.1093\/icvts\/ivaa319","type":"journal-article","created":{"date-parts":[[2021,1,22]],"date-time":"2021-01-22T04:28:57Z","timestamp":1611289737000},"page":"724-726","source":"Crossref","is-referenced-by-count":2,"title":["3-dimensional printing for the diagnosis of left ventricular outflow tract obstruction after mitral valve replacement"],"prefix":"10.1093","volume":"32","author":[{"given":"Ralf","family":"Sodian","sequence":"first","affiliation":[{"name":"Department of Thoracic and Cardiac Surgery, Heart Center, Lahr, Germany"},{"name":"Department of Cardiac Surgery, Ludwig-Maximilians-University, Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9614-687X","authenticated-orcid":false,"given":"Michael","family":"Kruttschnitt","sequence":"additional","affiliation":[{"name":"Institute of Micro Technology and Medical Device Technology, Technical University of Munich, Garching, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niklas","family":"Hitschrich","sequence":"additional","affiliation":[{"name":"TOMTEC Imaging Systems GmbH, Unterschlei\u00dfheim, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernhard","family":"Mumm","sequence":"additional","affiliation":[{"name":"TOMTEC Imaging Systems GmbH, Unterschlei\u00dfheim, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Schnell","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Angiology, Heart Center, Lahr, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Hagl","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Ludwig-Maximilians-University, Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1103-3775","authenticated-orcid":false,"given":"Nikolaus","family":"Thierfelder","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Ludwig-Maximilians-University, Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2345-8543","authenticated-orcid":false,"given":"Fabian","family":"K\u00f6nig","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Ludwig-Maximilians-University, Munich, Germany"},{"name":"Institute of Medical Materials and Implants, Technical University of Munich, Garching, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2021,2,27]]},"reference":[{"key":"2022011420073807500_ivaa319-B1","doi-asserted-by":"crossref","first-page":"1165","DOI":"10.1111\/echo.14370","article-title":"Mechanisms, pathophysiology, and diagnostic imaging of left ventricular outflow tract obstruction following mitral valve surgery and transcatheter mitral valve replacement","volume":"36","author":"Silbiger","year":"2019","journal-title":"Echocardiography"},{"key":"2022011420073807500_ivaa319-B2","doi-asserted-by":"crossref","first-page":"2521","DOI":"10.1016\/j.jacc.2019.02.076","article-title":"Anterior leaflet laceration to prevent ventricular outflow tract obstruction during transcatheter mitral valve replacement","volume":"73","author":"Khan","year":"2019","journal-title":"J Am Coll Cardiol"},{"key":"2022011420073807500_ivaa319-B3","doi-asserted-by":"crossref","first-page":"602","DOI":"10.1111\/echo.14255","article-title":"Malaligned bioprosthetic valve causing left ventricular outflow tract obstruction","volume":"36","author":"Christia","year":"2019","journal-title":"Echocardiography"},{"key":"2022011420073807500_ivaa319-B4","first-page":"I78","article-title":"Left ventricular outflow obstruction after mitral valve repair (carpentier's technique).
